OSB XQuery Issue

Question

Hi,
I have an xml A containing 100 elements.
I have an xml B containing 500 elements out of which 75 are mandatory while rest are optional.
I am transforming from xml A to xml B using XQuery Transformation.
While transforming, the mandatory ones in xml B are coming perfectly, but the optional ones are coming empty.
For example:
Incoming xml:
<Name>
<FirstName>John</FirstName>
</Name>
Expected Response:
<NAME>
<FNAME>John</FNAME>
</NAME>
If element <FirstName> is not present I get the empty node in my transformed xml.
Eg.
<NAME>
<FNAME/>
</NAME>
Is there any way to avoid the empty node tag without specifically adding IF ELSE conditions.
I am working on OSB 11.1.1.5
Please help.
Regards,
Karthik

Hi Karthik,
There is no if/then/else in xquery, in xquery you use FLOWR.
http://www.w3schools.com/xquery/xquery_flwor.asp
<NAME>
for $a in (/Name/FirstName)
return
<FNAME>data($a)</FNAME>
</NAME>This will omit the FNAME if there is no FirstName...
Note that I didn't verify the syntax, but I think you'll get the idea...
Cheers,
