Re: How Can You Exit an xsl:for-each Loop Prematurely?

[Michael Teigman <michael.teigman@xxxxxxxxxxx>]

I was afraid that using the example with a null was going to oversimplify the
problem.

Here is a portion of my actual XLM which I am supplied and have no control over.

<METADATA>
     <CODES CLASS="CATEGORY">
          <CODE CODE="NEWS"/>
          <CODE CODE="IT"/>
          <CODE CODE="DE"/>
          <CODE CODE="EUROPE"/>
          <CODE CODE="CRIM"/>
          <CODE CODE="GB"/>
          <CODE CODE="ODD"/>
     </CODES>
</METADATA>

<StringMap>
     <textIn SupCat="AAA" iCat="Ratings News"/>
     <textIn SupCat="ADV" iCat="Advertising"/>
     <textIn SupCat="ODD" iCat="Human Interest"/>
     <textIn SupCat="GB" iCat="Great Britain"/>
</StringMap>

The actual transformation is to see if any CODE attribute in the METADATA
matches any SupCat in the StringMap and if it does then output the iCat value.

BUT I want to output only one match, i.e., if there is more than one match (as
in this case GB and ODD both match) I want only one of them.

I would also like it to be determinant which would be output given the ordering
in the METADATA and/or the StringMap.

I am able to write a transform which gets all of the matches but not only the
"first".

Try something like this:

<xsl:for-each select="//Salesman/Orders/@Order[string(.) != ''][1]">
    ...output something...
</xsl:for-each/>

The first bracket should eliminate empty attributes, and the second should
restrict the search to the
first one only.
