[xsl] First Occurance Problem

["Deepak Rao" <deepaksubs@xxxxxxxxxxx>]

Hi,

Pl pardon my ignorance if this turns out to be a FAQ question. I tried to 
search biglist.com, to no avail.

I have the following template

<agg1>
  <agg2>             <----Can repeat 1 to N times
     <tag1></tag1>   <----Both tag1 and tag2 can be empty
     <tag2></tag2>
  </agg2>
</agg1>

Problem:

I want to return a xml with the following template

<agg1>
  <agg2>             <----Can occur only once
     <tagx></tagx>   <----tag1 will have the value from the first
                          populated occurance of tag1 in the source xml
  </agg2>
</agg1>

The sample source xml is

<agg1>
  <agg2>
     <tag2>value tag2-1</tag2>
  </agg2>
  <agg2>
     <tag1>value tag1</tag1>
  </agg2>
  <agg2>
     <tag2>value tag2-2</tag2>
  </agg2>
</agg1>

And the expected output is

<agg1>
  <agg2>
     <tagx>value tag1</tagx>
  </agg2>
</agg1>

I tried using templated and even the for-each loop, to no avail.

Can someone help me out.

Thanks,
Deepak
