I have XML Data:
<REQUEST>
<PARAMETERS>
<PPM Name="CCCS Filed Date" value="xxxx"></PPM>
</PARAMETERS>

<RECORD _FiledDate="12/15/2003"></RECORD>

</REQUEST>

I want to get data from @value {"xxxx"} if exist, otherwise get value
from @_FiledDate.

Please help me...

With XPath 2.0 you can do
if (/REQUEST/PARAMETERS/PPM/@value) then
/REQUEST/PARAMETERS/PPM/@value else /REQUEST/RECORD/@_FiledDate

With XPath 1.0 (and 2.0 of course) you can do
/REQUEST/PARAMETERS/PPM[@value]/@value |
/REQUEST[PARAMETERS/PPM[not(@value)]]/RECORD/@_FiledDate

ah yes I had it in mind that it was an xpath2 thread but looking back I
see that's not really justified.
