Re: Kxml: Issues with WbxmlParser.java in KXML2 rel. 2.1.8

Hi Stephan,

Thanks for your reply. I've downloaded the latest files under 
src/kxml/kxml2/src/org/kxml2/wap/ to get your fixes. One of the test files I 
was using failed with the latest changes, because of the commented out code 
in the method parseElement of the WbxmlParser class.

I think I understand what the problem is: by default, the attribute 
FEATURE_PROCESS_NAMESPACES is set to false in WbxmlParser. So, the code in 
parseElement:
       if (processNsp)
           adjustNsp();
       else
           namespace = "";
prevents adjustNsp() from being called. Therefore, the array nspCounts never 
grows. An example of xml that would not rountrip is: 
<a><b><c><d></d></c></b></a>, whereas <a><b><c></c></b></a> roundtrips 
correctly.

I tried to set FEATURE_PROCESS_NAMESPACES to true before parsing the wxbml 
of the example above, but still fails because adjustNsp() hasn't adjusted 
nspCounts. For now, I am going to keep the code uncommented until I figure 
out how nspCounts works.

Eric,

thanks a lot for your help!

Actually, most of the issues were already fixed in the version available via 
public CVS, but there was no new release yet because I still have a bunch of 
changes from Bogdan Onoi I still need to apply...

The commented code was made obsolete by the adjustNsp() method. Can you 
provide any hint how to reproduce the problem, perhaps an xml fragment I can 
feed to the roundtrip so I can figure out what's going wrong with that?

I have added a Wbxml rountdtrip example to the version available in CVS:

Cheers,
Stefan
