From: spam02 at pornel dot net Operating system: * PHP version: 6CVS-2006-08-21 (snap) PHP Bug Type: DOM XML related Bug description: loadHTML doesn't use XHTML namespace
Description: ------------ >From W3C: XHTML/1.0 is a reformulation of HTML 4 in XML. The semantics of HTML and XHTML elements are identical. loadHTML() should put loaded elements in XHTML namespace to preserve their semantics. These aren't just any random elements - these are HTML elements, and HTML elements in XML (therefore DOM) are in "http://www.w3.org/1999/xhtml"; namespace. This isn't purely academic problem. It's difficult to handle both HTML and XHTML uniformly using DOM in PHP - difference in namespaces causes xpath/XSLT to behave differently. AFAIK there's no trivial method of changing namespace of all document elements, so namespace returned by loadHTML() is quite important. SUGGESTED CHANGE Simply putting elements in a namespace will break backwards-compatibility a little (xpath queries for example). Therefore I suggest adding optional boolean argument to loadHTML() and loadHTMLFile() that enables new behavior. Reproduce code: --------------- <?php $html = new DOMDocument(); $html->loadHTML('<html><body>hello'); $xhtml = new DOMDocument(); $xhtml->loadXML('<html xmlns="http://www.w3.org/1999/xhtml";><body>hello</body></html>'); function test($doc) { $x = new DOMXPath($doc); $x->registerNamespace("x","http://www.w3.org/1999/xhtml";); echo $x->evaluate("string(//x:body)"); } test($html); test($xhtml); // local-name() could be used as workaround in this practicular text-case, however this isn't possible/feasible in every case.
