27 * This class is a collection of static functions that serve two purposes:
29 * 1) Implement any algorithms specified by HTML5, or other HTML
30 * specifications, in a convenient and self-contained way.
32 * 2) Allow HTML elements to be conveniently and safely generated, like the
33 * current Xml class but a) less confused (Xml supports HTML-specific things,
34 * but only sometimes!) and b) not necessarily confined to XML-compatible
37 * There are two important configuration options this class uses:
39 * $wgHtml5: If this is set to false, then all output should be valid XHTML 1.0
41 * $wgWellFormedXml: If this is set to true, then all output should be
42 * well-formed XML (quotes on attributes, self-closing tags, etc.).
44 * This class is meant to be confined to utility functions that are called from
45 * trusted code paths. It does not do enforcement of policy like not allowing

118 * Returns an HTML element in a string. The major advantage here over
119 * manually typing out the HTML is that it will escape all attribute
120 * values. If you're hardcoding all the attributes, or there are none, you
121 * should probably just type out the html element yourself.
123 * This is quite similar to Xml::tags(), but it implements some useful
124 * HTML-specific logic. For instance, there is no $allowShortTag
125 * parameter: the closing tag is magically omitted if $element has an empty
126 * content model. If $wgWellFormedXml is false, then a few bytes will be
127 * shaved off the HTML output as well.

419 * Attributes that should contain space-separated lists (such as 'class') array
420 * values are allowed as well, which will automagically be normalized

441 * @param $attribs array Associative array of attributes, e.g., array(
442 * 'href' => 'http://www.mediawiki.org/' ). Values will be HTML-escaped.
443 * A value of false means to omit the attribute. For boolean attributes,
444 * you can omit the key, e.g., array( 'checked' ) instead of
445 * array( 'checked' => 'checked' ) or such.
446 * @return string HTML fragment that goes between element name and '>'
447 * (starting with a space if at least one attribute is output)
