Test null properties in JXPATH

[Jasmina Desai <ja...@yahoo.com>]

Hi,

I have several objects of an objectwhich I need to
filter using JXPATH by checking a particular property
in that object.

I want to get only those instances which have avalid
value of a property. The property could be null also.

In such a case how should my xpath look like to filter
out only those instances which have 
property != null. 

For eg: object/property != null

How to check for null properties in objects using
jxpath?

Thanks in advance!

I've been playing with this for awhile but with a pure
xpath this is somewhat difficult.  If it were me I'd
probably use a custom function.

HTH,
