JRXMLDataSource determining current node name

2005-06-16 05:42

Hi all,

Is there a way to determine the current node name? Let's assume the report contains of rows <-> XML nodes of different type and we want to customize look of the row based on this type. Note that fields with XPath like "name(.)" doesn't not work here, because XPath has to return node set, not string.

If there is no such method - what about the patch below?

(patch to JRXmlDataSource from jasper 0.6.7)

 

best regards,

Michal Kostrzewa

OK, the patch is not quite readable from here, I'll add it to patch section on sourceforge
