CHANGELOG
------------------------------------
3.8 (2017-09-25)
- New site config directive: strip_attr: XPath attribute selector (e.g. //img/@srcset) - remove attribute from element
- New site config directive: insert_detected_image: yes/no (default yes) - places image in og:image in the body if no other images extracted
- Bug fix: Better handling of Internationalized Domain Names (IDNs)
- Bug fix: Relative base URLs (<base>) now resolved against page URL
- Bug fix: Wrong site config file chosen in certain cases (when wildcard and exact subdomain files available and cached in APCu)
- Bug fix: &apos; HTML entities not converted correctly when parsing with Gumbo PHP
- Remove srcset (+ sizes) attributes on img elements if it looks like they only contain relative URLs (browser will use src attribute value instead)
- https:// URLs now re-written to sec:// before being submitted to avoid overzealous security software blocking request on some servers - no redirect, only affects newly submitted URLs on index.php
- HTML5-PHP library updated
- Language Detect library updated
- Site config files updated for better extraction
- Minimum PHP version is now 5.4. If you must use PHP 5.3, please stick with Full-Text RSS 3.7
- Tested with PHP 7.2
- Other fixes/improvements
3.7 (2017-02-12)
- Request HTML5 output using HTML5-PHP - new config option $options->html5_output and new request parameter &content=html5
- Improve support for lazy-loading images

// HTML5 output
// ----------------------
// By default, Full-Text RSS uses libxml to convert the parsed DOM tree back into HTML.
// If this is enabled, we'll use HTML5-PHP to produce the HTML. This will be a little
// slower, but might produce better results, adhering to the HTML5 spec.
//
// Note: in a future release we might make HTML5 output the default.
// Full-Text RSS used to rely on libxml to output HTML extracted from
// a web page. Since version 3.8 we use HTML5-PHP by default.
// If you prefer the old output, either set this to false or pass &content=1
// in the querystring.

<h3>Further info</h3>
<h4>IDN support</h4>
<p>When treating an <a href="https://en.wikipedia.org/wiki/Internationalized_domain_name">internationalized domain name (IDN)</a> Full-Text RSS will try to make use of PHP's <code>idn_to_ascii</code> function to convert the domain to ASCII. If this function does not exist, you might have trouble retrieving article content from internationalized domains.</p>
<p class="highlight"><strong>idn_to_ascii</strong> is <?php if (!$idn_ok) echo '<strong>not</strong>'; ?> available on this server.</p>
<h4>HTTP module</h4>
<p>Full-Text RSS can make use of PHP's HTTP extension or <code>curl_multi</code> to make parallel HTTP requests when processing feeds. If neither are available, it will make sequential requests using <code>file_get_contents</code>.</p>

# HTML5-PHP
The need for an HTML5 parser in PHP is clear. This project initially
began with the seemingly abandoned `html5lib` project [original source](https://code.google.com/p/html5lib/source/checkout).
But after some initial refactoring work, we began a new parser.
HTML5 is a standards-compliant HTML5 parser and writer written entirely in PHP.
It is stable and used in many production websites, and has
well over [one million downloads](https://packagist.org/packages/masterminds/html5).
HTML5 provides the following features.
- An HTML5 serializer
- Support for PHP namespaces
- Composer support
- Event-based (SAX-like) parser
- DOM tree builder
- A DOM tree builder
- Interoperability with [QueryPath](https://github.com/technosophos/querypath)
- Runs on **PHP** 5.3.0 or newer and **HHVM** 3.2 or newer
