I've been trying to use XPath in both the nightly Safari and the stable release; and it just won't work; any
clearity on how to use, if usable, XPath in Webkit would be appreciated.
A sample document; which works in Firefox and Camino;
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN">
<html>
<head>
<title>Safari XPath test</title>
<style>
.bla { border: 1px solid red;}
</style>
</head>
<body>
<dl>
<dt>lorem</dt>
<dd>ipsum</dd>
<dd>another one</dd>
<dt>next</dt>
<dd>follow-up</dd>
</dl>
<script>
var iterator = document.evaluate("/html/body", document, null, 0, null);
while(item = iterator.iterateNext())
{
item.className = 'bla';
}
</script>
</body>
</html>
No matter what XPath query I used (I was trying //dl/dt[1]/following-sibling::dd[1]) - always get the
error:
TypeError: value undefined (result of expression document.evaluate) is not object.

I asked in IRC and found out that XPath evaluation isn't claimed to work. IIRC, it also isn't
on the near-term radar either.
That's too bad, as I could really use this facility.

Confirmed on request of Paul Everitt.

Folks on the KDE side, in the library KDOM (which stems from a very similar code base to WebCore)
already have two working xpath implementations. One for 1.0 and a partial one for 2.0. It's possible that
someone could port one of these into WebCore with relatively minimal effort.

I am evaluating Safari for a port of TIBCO(R) General Interface, a mature AJAX platform that is currently IE
only. Fixing this bug would make the port more feasible.
