XPath function

[Mitchell Harris]

Is there a way to get at the XPath functions as defined on w3schols?

The following code:

var ns={'ns1':'http://www.itunes.com/dtds/podcast-1.0.dtd',

 'fn':'http://www.w3.org/2005/xpath-functions'

}

var elems = doc.find("//item[fn:lower-case(ns1:duration)='2:00']",ns);

Reports the following error.

function lower-case not found

XPath error : Unregistered function

Do you know if libxml2 supports XPath functions? I can't find the appropriate documentation. If it's supported by libxml2 I'll try to add support to libxmljs.

Hello,

It seems some functions are defined in libxml2 but not lower-case.
They are listed here (everything ending with function I guess) and you have the corresponding sources here.
You could also register new functions to fill the gaps but that should definitely belong to libxml2.
