HTML To Markdown for PHP
|
||||
========================
|
||||
|
||||
A helper class that converts HTML to [Markdown](http://daringfireball.net/projects/markdown/) for your sanity and convenience.
|
||||
|
||||
[](https://travis-ci.org/nickcernis/html-to-markdown)
|
||||
|
||||
**Version**: 2.2.1
|
||||
**Requires**: PHP 5.3+
|
||||
**Author**: [@nickcernis](http://twitter.com/nickcernis)
|
||||
**License**: [MIT](http://www.opensource.org/licenses/mit-license.php)
|
||||
|
||||
### Why convert HTML to Markdown?
|
||||
|
||||
*"What alchemy is this?"* you mutter. *"I can see why you'd convert [Markdown to HTML](http://michelf.com/projects/php-markdown/),"* 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
|
||||
|
||||
Either include HTML_To_Markdown.php directly:
|
||||
|
||||
require_once( dirname( __FILE__) . '/HTML_To_Markdown.php' );
|
||||
|
||||
Or, require the library in your composer.json:
|
||||
|
||||
{
|
||||
"require": {
|
||||
"nickcernis/html-to-markdown": "dev-master"
|
||||
}
|
||||
}
|
||||
|
||||
Then `composer install` and add `require 'vendor/autoload.php';` to the top of your script.
|
||||
|
||||
Next, create a new HTML_To_Markdown instance, passing in your valid HTML code:
|
||||
|
||||
$html = "<h3>Quick, to the Batpoles!</h3>";
|
||||
$markdown = new HTML_To_Markdown($html);
|
||||
|
||||
The `$markdown` object now contains the Markdown version of your HTML. Use it like a string:
|
||||
|
||||
echo $markdown; // ==> ### Quick, to the Batpoles!
|
||||
|
||||
Or access the Markdown output directly:
|
||||
|
||||
$string = $markdown->output();
|
||||
|
||||
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:
|
||||
|
||||
$html = '<span>Turnips!</span>';
|
||||
$markdown = new HTML_To_Markdown($html, array('strip_tags' => true)); // $markdown now contains "Turnips!"
|
||||
|
||||
Or more explicitly, like this:
|
||||
|
||||
$html = '<span>Turnips!</span>';
|
||||
$markdown = new HTML_To_Markdown();
|
||||
$markdown->set_option('strip_tags', true);
|
||||
$markdown->convert($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:
|
||||
|
||||
$html = '<span>Turnips!</span><div>Monkeys!</div>';
|
||||
$markdown = new HTML_To_Markdown($html, array('remove_nodes' => 'span div')); // $markdown now contains ""
|
||||
|
||||
### Style options
|
||||
|
||||
Bold and italic tags are converted using the asterisk syntax by default. Change this to the underlined syntax using the `bold_style` and `italic_style` options.
|
||||
|
||||
$html = '<em>Italic</em> and a <strong>bold</strong>';
|
||||
$markdown = new HTML_To_Markdown();
|
||||
$markdown->set_option('italic_style', '_');
|
||||
$markdown->set_option('bold_style', '__');
|
||||
$markdown->convert($html); // $markdown now contains "_Italic_ and a __bold__"
|
||||
|
||||
### Limitations
|
||||
|
||||
- Markdown Extra, MultiMarkdown and other variants aren't supported – just Markdown.
|
||||
|
||||
### Known issues
|
||||
|
||||
- Nested lists and lists containing multiple paragraphs aren't converted correctly.
|
||||
- Lists inside blockquotes aren't converted correctly.
|
||||
- Any reported [open issues here](https://github.com/nickcernis/html-to-markdown/issues?state=open).
|
||||
|
||||
[Report your issue or request a feature here.](https://github.com/nickcernis/html2markdown/issues/new) Issues with patches or failing tests are especially welcome.
|
||||
|
||||
### Style notes
|
||||
|
||||
- Setext (underlined) headers are the default for H1 and H2. If you prefer the ATX style for H1 and H2 (# Header 1 and ## Header 2), set `header_style` to 'atx' in the options array when you instantiate the object:
|
||||
|
||||
`$markdown = new HTML_To_Markdown( $html, 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.
|
||||
|
||||
### Architecture notes
|
||||
|
||||
HTML To Markdown is a single file that uses native DOM manipulation libraries (DOMDocument), not regex voodoo, to convert code.
|
||||
|
||||
### Contributors
|
||||
|
||||
Many thanks to all [contributors](https://github.com/nickcernis/html2markdown/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 [PHP Markdown](http://michelf.com/projects/php-markdown/) from Michel Fortin. No guarantees about the Elvish, though.

Library which converts HTML to [Markdown](http://daringfireball.net/projects/markdown/) for your sanity and convenience.
|
||||
|
||||
|
||||
**Requires**: PHP 5.3+
|
||||
|
||||
**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 ""
|
||||
```
|
||||
|
||||
### Style options
|
||||
|
||||
Bold and italic tags are converted using the asterisk syntax by default. Change this to the underlined syntax 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"
|
||||
```
|
||||
|
||||
### 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); // $markdown now contains "### Header" and "<img src="" />"
|
||||
```
|
||||
|
||||
### Limitations
|
||||
|
||||
- Markdown Extra, MultiMarkdown and other variants aren't supported – just Markdown.
|
||||
|
||||
### Known issues
|
||||
|
||||
- Nested lists and lists containing multiple paragraphs aren't converted correctly.
|
||||
- Lists inside blockquotes aren't converted correctly.
|
||||
- Any reported [open issues here](https://github.com/thephpleague/html-to-markdown/issues?state=open).
|
||||
|
||||
[Report your issue or request a feature here.](https://github.com/thephpleague/html-to-markdown/issues/new) Issues with patches or failing tests are especially welcome.
|
||||
|
||||
### Style notes
|
||||
|
||||
- Setext (underlined) headers are the default for H1 and H2. If you prefer the ATX style for H1 and H2 (# Header 1 and ## Header 2), set `header_style` to 'atx' in the options array when you instantiate the object:
|
||||
|
||||
`$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.
