Xpath in GWT

[Raja]

Hi,

Can someone please help me in using xpath in GWT?
I tried smartgwt xmltools. it is failing.
Is there any alternative for this?

Here is the exception snippet:

Feel free to take a look at Totoe: http://code.google.com/p/totoe/ 

Totoe is a XML parser with json/xpath and namespace support. If you want to take a quick look at Totoes features check out http://totoe-tester.appspot.com/. There you can enter arbitrary JSON / XML and test your XPath / JSONPath expressions.

I am interested in this! We need better support for XML and XPath in GWT (and it needs to work fast).

The standard GWT wrapper on top of the browser XML support is very much incomplete.

 

But I see that totoe does not allow modifying the document.

Is it planned to implement this in the forseable future ?

 

[Harald Pehl]

I agree, modification would be a nice feature. Unfortunately Totoe is one of my spare time projects and recently I do not have much time to implement new features.
