Hi,

I need to check the existence of optional filed,Could anyone help me on
this.
In the below input file,i want to wheather elment <ECertified>Exists or not.

I have tried in my way,But it is throwing exception in case elment
doesn't exist.
xpath>>Count(//Company//Emp[1]//ECertified).




i/p file:
<Company>

<Emp>
<Eno>1</ENo>
<EName>AAA</Ename>
</Emp>

<Emp>
<Eno>2</ENo>
<EName>bbb</Ename>
<ECertified>Yes</ECertified>
</Emp>


</Company>



Thanks,
Prakash

Your xpath query looks a bit weird. Please try:
count(/Company/Emp[1]/ECertified)

Maybe that will do the trick. At least count should return 0 if the
element isn't there, but make sure that there's at least one Emp
element, else it probably won't work!
