I am a newbie to XSL and am hoping that somebody can help me with the
following scenario. I tried to use xsl:variable but was not successful. :(
 
I
have an "errorDescription" element in the target structure. Depending on the
error condition result on input fields, I have to concatenate the field names
(that are in error) and post them to the errorDescription field.
 
How can I
do it?  Any help is appreciated.
 
sample input.
 
<request>
 <header>
<address1>1234</address1>
  <address2></address2>
  <address3>3456</address3>
<address4></address4>
 </header>
</request>
 
If all address elements are
expected to have values, and 2nd and 4th don't have values the output file
should look like:
 
<response>
 <header>
  <address1>1234</address1>
<address3>3456</address3>
  <errorDescription>Invalid Elements:
Address2,Address4</errorDescription
 </header>
</response>
 
Thanks in advance
for your help.
