createElementNS() does not work as expected in new versions of Xerces ( > 2.0.1) 2003-05-26 - By Thomas Börkel
HI!
We used createElementNS() in 2.0.1 successfully. Since we switched to newer
versions (now 2.4.0), it stopped working as expected. We have reviewed our code
and changed it as suggested in http://nagoya.apache.org/bugzilla/show_bug.cgi
?idv87 with no positive effect.
Using 2.0.1, the test code below produces:
<root><testNode xmlns="http://schemas.p2plus.com/test/"/></root>
<root><testNode xmlns="http://schemas.p2plus.com/test/"/></root>
Using 2.4.0, the test code below produces:
<root><testNode/></root>
<root><testNode xmlns=""/></root>
Any help would be greatly appreciated. Thanks!
Regards,
Thomas
