+ *
+ *     // register classes with namespaces
+ *     $loader->add('Symfony\Component', __DIR__.'/component');
+ *     $loader->add('Symfony',           __DIR__.'/framework');

+ *
+ * In this example, if you try to use a class in the Symfony\Component
+ * namespace or one of its children (Symfony\Component\Console for instance),
+ * the autoloader will first look for the class under the component/
+ * directory, and it will then fallback to the framework/ directory if not
+ * found before giving up.
+ *
+ * This class is loosely based on the Symfony UniversalClassLoader.

+
+Library which converts HTML to [Markdown](http://daringfireball.net/projects/markdown/) for your sanity and convenience.
+
+
+**Requires**: PHP 7.2+
+
+**Lead Developer**: [@colinodell](http://twitter.com/colinodell)
+
+**Original Author**: [@nickcernis](http://twitter.com/nickcernis)
+
+
+### Why convert HTML to Markdown?
+
+*"What alchemy is this?"* you mutter. *"I can see why you'd convert [Markdown to HTML](https://github.com/thephpleague/commonmark),"* you continue, already labouring the question somewhat, *"but why go the other way?"*
+
+Typically you would convert HTML to Markdown if:
+
+1. You have an existing HTML document that needs to be edited by people with good taste.
+2. You want to store new content in HTML format but edit it as Markdown.
+3. You want to convert HTML email to plain text email.
+4. You know a guy who's been converting HTML to Markdown for years, and now he can speak Elvish. You'd quite like to be able to speak Elvish.
+5. You just really like Markdown.
+
+### How to use it
+
+Require the library by issuing this command:
+
+```bash
+composer require league/html-to-markdown
+```
+
+Add `require 'vendor/autoload.php';` to the top of your script.
+
+Next, create a new HtmlConverter instance, passing in your valid HTML code to its `convert()` function:
+
+```php
+use League\HTMLToMarkdown\HtmlConverter;
+
+$converter = new HtmlConverter();
+
+$html = "<h3>Quick, to the Batpoles!</h3>";
+$markdown = $converter->convert($html);
+```
+
+The `$markdown` variable now contains the Markdown version of your HTML as a string:
+
+```php
+echo $markdown; // ==> ### Quick, to the Batpoles!
+```
+
+The included `demo` directory contains an HTML->Markdown conversion form to try out.
+
+### Conversion options
+
+By default, HTML To Markdown preserves HTML tags without Markdown equivalents, like `<span>` and `<div>`.
+
+To strip HTML tags that don't have a Markdown equivalent while preserving the content inside them, set `strip_tags` to true, like this:
+
+```php
+$converter = new HtmlConverter(array('strip_tags' => true));
+
+$html = '<span>Turnips!</span>';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!"
+```
+
+Or more explicitly, like this:
+
+```php
+$converter = new HtmlConverter();
+$converter->getConfig()->setOption('strip_tags', true);
+
+$html = '<span>Turnips!</span>';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!"
+```
+
+Note that only the tags themselves are stripped, not the content they hold.
+
+To strip tags and their content, pass a space-separated list of tags in `remove_nodes`, like this:
+
+```php
+$converter = new HtmlConverter(array('remove_nodes' => 'span div'));
+
+$html = '<span>Turnips!</span><div>Monkeys!</div>';
+$markdown = $converter->convert($html); // $markdown now contains ""
+```
+
+By default, all comments are stripped from the content. To preserve them, use the `preserve_comments` option, like this:
+
+```php
+$converter = new HtmlConverter(array('preserve_comments' => true));
+
+$html = '<span>Turnips!</span><!-- Monkeys! -->';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!<!-- Monkeys! -->"
+```
+
+To preserve only specific comments, set `preserve_comments` with an array of strings, like this:
+
+```php
+$converter = new HtmlConverter(array('preserve_comments' => array('Eggs!')));
+
+$html = '<span>Turnips!</span><!-- Monkeys! --><!-- Eggs! -->';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!<!-- Eggs! -->"
+```
+
+By default, placeholder links are preserved. To strip the placeholder links, use the `strip_placeholder_links` option, like this:
+
+```php
+$converter = new HtmlConverter(array('strip_placeholder_links' => true));
+
+$html = '<a>Github</a>';
+$markdown = $converter->convert($html); // $markdown now contains "Github"
+```
+
+### Style options
+
+By default bold tags are converted using the asterisk syntax, and italic tags are converted using the underlined syntax. Change these by using the `bold_style` and `italic_style` options.
+
+```php
+$converter = new HtmlConverter();
+$converter->getConfig()->setOption('italic_style', '*');
+$converter->getConfig()->setOption('bold_style', '__');
+
+$html = '<em>Italic</em> and a <strong>bold</strong>';
+$markdown = $converter->convert($html); // $markdown now contains "*Italic* and a __bold__"
+```
+
+### Line break options
+
+By default, `br` tags are converted to two spaces followed by a newline character as per [traditional Markdown](https://daringfireball.net/projects/markdown/syntax#p). Set `hard_break` to `true` to omit the two spaces, as per GitHub Flavored Markdown (GFM).
+
+```php
+$converter = new HtmlConverter();
+$html = '<p>test<br>line break</p>';
+
+$converter->getConfig()->setOption('hard_break', true);
+$markdown = $converter->convert($html); // $markdown now contains "test\nline break"
+
+$converter->getConfig()->setOption('hard_break', false); // default
+$markdown = $converter->convert($html); // $markdown now contains "test  \nline break"
+```
+
+### Autolinking options
+
+By default, `a` tags are converted to the easiest possible link syntax, i.e. if no text or title is available, then the `<url>` syntax will be used rather than the full `[url](url)` syntax. Set `use_autolinks` to `false` to change this behavior to always use the full link syntax.
+
+```php
+$converter = new HtmlConverter();
+$html = '<p><a href="https://thephpleague.com">https://thephpleague.com</a></p>';
+
+$converter->getConfig()->setOption('use_autolinks', true);
+$markdown = $converter->convert($html); // $markdown now contains "<https://thephpleague.com>"
+
+$converter->getConfig()->setOption('use_autolinks', false); // default
+$markdown = $converter->convert($html); // $markdown now contains "[https://google.com](https://google.com)"
+```
+
+### Passing custom Environment object
+
+You can pass current `Environment` object to customize i.e. which converters should be used.
+
+```php
+$environment = new Environment(array(
+    // your configuration here
+));
+$environment->addConverter(new HeaderConverter()); // optionally - add converter manually
+
+$converter = new HtmlConverter($environment);
+
+$html = '<h3>Header</h3>
+<img src="" />
+';
+$markdown = $converter->convert($html); // $markdown now contains "### Header" and "<img src="" />"
+```
+
+### Table support
+
+Support for Markdown tables is not enabled by default because it is not part of the original Markdown syntax. To use tables add the converter explicitly:
+
+```php
+use League\HTMLToMarkdown\HtmlConverter;
+use League\HTMLToMarkdown\Converter\TableConverter;
+
+$converter = new HtmlConverter();
+$converter->getEnvironment()->addConverter(new TableConverter());
+
+$html = "<table><tr><th>A</th></tr><tr><td>a</td></tr></table>";
+$markdown = $converter->convert($html);
+```
+
+### Limitations
+
+- Markdown Extra, MultiMarkdown and other variants aren't supported – just Markdown.
+
+### Style notes
+
+- Setext (underlined) headers are the default for H1 and H2. If you prefer the ATX style for H1 and H2 (# Header 1 and ## Header 2), set `header_style` to 'atx' in the options array when you instantiate the object:
+
+    `$converter = new HtmlConverter(array('header_style'=>'atx'));`
+
+     Headers of H3 priority and lower always use atx style.
+
+- Links and images are referenced inline. Footnote references (where image src and anchor href attributes are listed in the footnotes) are not used.
+- Blockquotes aren't line wrapped – it makes the converted Markdown easier to edit.
+
+### Dependencies
+
+HTML To Markdown requires PHP's [xml](http://www.php.net/manual/en/xml.installation.php), [lib-xml](http://www.php.net/manual/en/libxml.installation.php), and [dom](http://www.php.net/manual/en/dom.installation.php) extensions, all of which are enabled by default on most distributions.
+
+Errors such as "Fatal error: Class 'DOMDocument' not found" on distributions such as CentOS that disable PHP's xml extension can be resolved by installing php-xml.
+
+### Contributors
+
+Many thanks to all [contributors](https://github.com/thephpleague/html-to-markdown/graphs/contributors) so far. Further improvements and feature suggestions are very welcome.
+
+### How it works
+
+HTML To Markdown creates a DOMDocument from the supplied HTML, walks through the tree, and converts each node to a text node containing the equivalent markdown, starting from the most deeply nested node and working inwards towards the root node.
+
+### To-do
+
+- Support for nested lists and lists inside blockquotes.
+- Offer an option to preserve tags as HTML if they contain attributes that can't be represented with Markdown (e.g. `style`).
+
+### Trying to convert Markdown to HTML?
+
+Use one of these great libraries:
+
+ - [league/commonmark](https://github.com/thephpleague/commonmark) (recommended)
+ - [cebe/markdown](https://github.com/cebe/markdown)
+ - [PHP Markdown](https://michelf.ca/projects/php-markdown/)
+ - [Parsedown](https://github.com/erusev/parsedown)
+
+No guarantees about the Elvish, though.

+
+Library which converts HTML to [Markdown](http://daringfireball.net/projects/markdown/) for your sanity and convenience.
+
+
+**Requires**: PHP 7.2+
+
+**Lead Developer**: [@colinodell](http://twitter.com/colinodell)
+
+**Original Author**: [@nickcernis](http://twitter.com/nickcernis)
+
+
+### Why convert HTML to Markdown?
+
+*"What alchemy is this?"* you mutter. *"I can see why you'd convert [Markdown to HTML](https://github.com/thephpleague/commonmark),"* you continue, already labouring the question somewhat, *"but why go the other way?"*
+
+Typically you would convert HTML to Markdown if:
+
+1. You have an existing HTML document that needs to be edited by people with good taste.
+2. You want to store new content in HTML format but edit it as Markdown.
+3. You want to convert HTML email to plain text email.
+4. You know a guy who's been converting HTML to Markdown for years, and now he can speak Elvish. You'd quite like to be able to speak Elvish.
+5. You just really like Markdown.
+
+### How to use it
+
+Require the library by issuing this command:
+
+```bash
+composer require league/html-to-markdown
+```
+
+Add `require 'vendor/autoload.php';` to the top of your script.
+
+Next, create a new HtmlConverter instance, passing in your valid HTML code to its `convert()` function:
+
+```php
+use League\HTMLToMarkdown\HtmlConverter;
+
+$converter = new HtmlConverter();
+
+$html = "<h3>Quick, to the Batpoles!</h3>";
+$markdown = $converter->convert($html);
+```
+
+The `$markdown` variable now contains the Markdown version of your HTML as a string:
+
+```php
+echo $markdown; // ==> ### Quick, to the Batpoles!
+```
+
+The included `demo` directory contains an HTML->Markdown conversion form to try out.
+
+### Conversion options
+
+By default, HTML To Markdown preserves HTML tags without Markdown equivalents, like `<span>` and `<div>`.
+
+To strip HTML tags that don't have a Markdown equivalent while preserving the content inside them, set `strip_tags` to true, like this:
+
+```php
+$converter = new HtmlConverter(array('strip_tags' => true));
+
+$html = '<span>Turnips!</span>';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!"
+```
+
+Or more explicitly, like this:
+
+```php
+$converter = new HtmlConverter();
+$converter->getConfig()->setOption('strip_tags', true);
+
+$html = '<span>Turnips!</span>';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!"
+```
+
+Note that only the tags themselves are stripped, not the content they hold.
+
+To strip tags and their content, pass a space-separated list of tags in `remove_nodes`, like this:
+
+```php
+$converter = new HtmlConverter(array('remove_nodes' => 'span div'));
+
+$html = '<span>Turnips!</span><div>Monkeys!</div>';
+$markdown = $converter->convert($html); // $markdown now contains ""
+```
+
+By default, all comments are stripped from the content. To preserve them, use the `preserve_comments` option, like this:
+
+```php
+$converter = new HtmlConverter(array('preserve_comments' => true));
+
+$html = '<span>Turnips!</span><!-- Monkeys! -->';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!<!-- Monkeys! -->"
+```
+
+To preserve only specific comments, set `preserve_comments` with an array of strings, like this:
+
+```php
+$converter = new HtmlConverter(array('preserve_comments' => array('Eggs!')));
+
+$html = '<span>Turnips!</span><!-- Monkeys! --><!-- Eggs! -->';
+$markdown = $converter->convert($html); // $markdown now contains "Turnips!<!-- Eggs! -->"
+```
+
+By default, placeholder links are preserved. To strip the placeholder links, use the `strip_placeholder_links` option, like this:
+
+```php
+$converter = new HtmlConverter(array('strip_placeholder_links' => true));
+
+$html = '<a>Github</a>';
+$markdown = $converter->convert($html); // $markdown now contains "Github"
+```
+
+### Style options
+
+By default bold tags are converted using the asterisk syntax, and italic tags are converted using the underlined syntax. Change these by using the `bold_style` and `italic_style` options.
+
+```php
+$converter = new HtmlConverter();
+$converter->getConfig()->setOption('italic_style', '*');
+$converter->getConfig()->setOption('bold_style', '__');
+
+$html = '<em>Italic</em> and a <strong>bold</strong>';
+$markdown = $converter->convert($html); // $markdown now contains "*Italic* and a __bold__"
+```
+
+### Line break options
+
+By default, `br` tags are converted to two spaces followed by a newline character as per [traditional Markdown](https://daringfireball.net/projects/markdown/syntax#p). Set `hard_break` to `true` to omit the two spaces, as per GitHub Flavored Markdown (GFM).
+
+```php
+$converter = new HtmlConverter();
+$html = '<p>test<br>line break</p>';
+
+$converter->getConfig()->setOption('hard_break', true);
+$markdown = $converter->convert($html); // $markdown now contains "test\nline break"
+
+$converter->getConfig()->setOption('hard_break', false); // default
+$markdown = $converter->convert($html); // $markdown now contains "test  \nline break"
+```
+
+### Autolinking options
+
+By default, `a` tags are converted to the easiest possible link syntax, i.e. if no text or title is available, then the `<url>` syntax will be used rather than the full `[url](url)` syntax. Set `use_autolinks` to `false` to change this behavior to always use the full link syntax.
+
+```php
+$converter = new HtmlConverter();
+$html = '<p><a href="https://thephpleague.com">https://thephpleague.com</a></p>';
+
+$converter->getConfig()->setOption('use_autolinks', true);
+$markdown = $converter->convert($html); // $markdown now contains "<https://thephpleague.com>"
+
+$converter->getConfig()->setOption('use_autolinks', false); // default
+$markdown = $converter->convert($html); // $markdown now contains "[https://google.com](https://google.com)"
+```
+
+### Passing custom Environment object
+
+You can pass current `Environment` object to customize i.e. which converters should be used.
+
+```php
+$environment = new Environment(array(
+    // your configuration here
+));
+$environment->addConverter(new HeaderConverter()); // optionally - add converter manually
+
+$converter = new HtmlConverter($environment);
+
+$html = '<h3>Header</h3>
+<img src="" />
+';
+$markdown = $converter->convert($html); // $markdown now contains "### Header" and "<img src="" />"
+```
+
+### Table support
+
+Support for Markdown tables is not enabled by default because it is not part of the original Markdown syntax. To use tables add the converter explicitly:
+
+```php
+use League\HTMLToMarkdown\HtmlConverter;
+use League\HTMLToMarkdown\Converter\TableConverter;
+
+$converter = new HtmlConverter();
+$converter->getEnvironment()->addConverter(new TableConverter());
+
+$html = "<table><tr><th>A</th></tr><tr><td>a</td></tr></table>";
+$markdown = $converter->convert($html);
+```
+
+### Limitations
+
+- Markdown Extra, MultiMarkdown and other variants aren't supported – just Markdown.
+
+### Style notes
+
+- Setext (underlined) headers are the default for H1 and H2. If you prefer the ATX style for H1 and H2 (# Header 1 and ## Header 2), set `header_style` to 'atx' in the options array when you instantiate the object:
+
+    `$converter = new HtmlConverter(array('header_style'=>'atx'));`
+
+     Headers of H3 priority and lower always use atx style.
+
+- Links and images are referenced inline. Footnote references (where image src and anchor href attributes are listed in the footnotes) are not used.
+- Blockquotes aren't line wrapped – it makes the converted Markdown easier to edit.
+
+### Dependencies
+
+HTML To Markdown requires PHP's [xml](http://www.php.net/manual/en/xml.installation.php), [lib-xml](http://www.php.net/manual/en/libxml.installation.php), and [dom](http://www.php.net/manual/en/dom.installation.php) extensions, all of which are enabled by default on most distributions.
+
+Errors such as "Fatal error: Class 'DOMDocument' not found" on distributions such as CentOS that disable PHP's xml extension can be resolved by installing php-xml.
+
+### Contributors
+
+Many thanks to all [contributors](https://github.com/thephpleague/html-to-markdown/graphs/contributors) so far. Further improvements and feature suggestions are very welcome.
+
+### How it works
+
+HTML To Markdown creates a DOMDocument from the supplied HTML, walks through the tree, and converts each node to a text node containing the equivalent markdown, starting from the most deeply nested node and working inwards towards the root node.
+
+### To-do
+
+- Support for nested lists and lists inside blockquotes.
+- Offer an option to preserve tags as HTML if they contain attributes that can't be represented with Markdown (e.g. `style`).
+
+### Trying to convert Markdown to HTML?
+
+Use one of these great libraries:
+
+ - [league/commonmark](https://github.com/thephpleague/commonmark) (recommended)
+ - [cebe/markdown](https://github.com/cebe/markdown)
+ - [PHP Markdown](https://michelf.ca/projects/php-markdown/)
+ - [Parsedown](https://github.com/erusev/parsedown)
+
+No guarantees about the Elvish, though.
