[Webmacro-devel] Slightly off topic: Good XPath impl anyone?

[Marc P. <ma...@an...>]

Hi all,

Does anyone know of a good (i.e. simple and small) XPath implementation 
that can work with regular W3C DOM nodes?

I would like to add at least something like XPath to our XML helper for WM 
templates, to make node selection a bit less boring in WM script. XSLT 
processors have
XPath implemented but we only want the XPath bit... and effectively we just 
want:

  public NodeList evaluateXPathExpression( Node context, String expression)

...so that in WMscript we can do things like:

#set $channels = $XMLHelper.find( "rss/channel")

Otherwise we currently have to find the "rss" nodes, then find the 
"channel" nodes under that etc. - boring and very longwinded if you are 
looking for something more than one or two levels deep.

I notice the XPath part of Apache Xalan-Java is available... but it looks a 
bit more complicated than what we need/want. I don't want to have to 
implement 10 interfaces just to get this working if I can avoid it.

TIA
