The HTML language module uses jsoup for parsing.

XPath rules are supported, but the DOM is not always a typical XML/XPath DOM. In the Designer, text nodes appear as nodes with name “#text”, but they can be selected as usual using text().

XML Namespaces are not supported. The local name of attributes includes the prefix, so that you have to select attributes by e.g. //*[@*[local-name() = 'if:true']].
