[OpenLayers-Dev] XPATH library to support GML parsing

[Cameron Shorter]

Mapbuilder has GML, WMC, SLD parsers which could be ported over 
OpenLayers. In particular, I'm considering porting the GML parser over 
to OpenLayers to provide a GML Layer.

In Mapbuilder we use XPATH for a lot of our parsing.
At other times, we use XSLT.
Xpath syntax looks something like:
selectSingleNode("//ows:BoundingBox/@crs")

The cross browser XPATH and XSLT functionality we use is provided by 
http://sarissa.sf.net . I assume other ajax frameworks like Dojo and 
Atom provide something similar.

While I'm not convinced that XSLT is required by OpenLayers yet, I think 
XPATH would be very useful.

I suggest that OpenLayers considers including all, or part of a library 
which supports XPATH. Sarissa is available under the LGPL, GPL and 
Apache Software Licence.
