HTML Pretty-Min
===============

HTML Pretty-Min is a PHP library for minifying and prettyprinting (indenting) HTML documents
that works directly on the DOM tree of an HTML document.
Currently it has the following features:
- **Prettyprint**:
- Indent Block-level elements, do not indent inline elements
- **Minify**:
- Remove whitespace and newlines
- Compress embedded Javascript using [mrclay/jsmin-php](https://packagist.org/packages/mrclay/jsmin-php)
- Compress embedded CSS using [tubalmartin/cssmin](https://packagist.org/packages/tubalmartin/cssmin)
- Remove some attributes when their value is empty (by default "style" and "class" attributes)
- Remove comments, except those matching some given regular expressions (by default, IE conditional comments are kept)
Installation
------------
HTML Pretty-Min is listed on [Packagist](https://packagist.org/packages/wa72/html-pretty-min).
`composer require wa72/html-pretty-min`
Usage
-----
```php
load($html) // $html may be a \DOMDocument, a string containing an HTML code,
// or an \SplFileInfo pointing to an HTML document
->minify()
->saveHtml();
```
For prettyprinting, call the `indent()` method instead of `minify()`.
**Attention**: Because the formatting is done directly on the DOM tree, a DOMDocument object given to the `load()` method
will be modified:
```php
$dom_document = new \DOMDocument('1.0', 'UTF-8');
$dom_document->loadHTML('...some html code...');
$pm->load($dom_document)->minify();
echo $dom_document->saveHTML(); // Will output the minified, not the original, document
```
