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

["Dan Machak" <machak@xxxxxxxxxxxx>]

Try this:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/XSL/Transform/1.0";>
<xsl:output indent="yes"/>

<xsl:template match="METADATA">
  <FIRST-IN-METADATA>
	<xsl:apply-templates
select="(CODES/CODE[@CODE=//StringMap/textIn/@SupCat])[1]"/>
  </FIRST-IN-METADATA>
</xsl:template>

<xsl:template match="StringMap">
  <FIRST-IN-StringMap>
	<xsl:apply-templates
select="(textIn[@SupCat=//METADATA/CODES/CODE/@CODE])[1]"/>
  </FIRST-IN-StringMap>
</xsl:template>

<xsl:template match="CODE">
  	<xsl:value-of select="@CODE"/>
</xsl:template>

<xsl:template match="textIn">
  	<xsl:value-of select="@SupCat"/>
</xsl:template>

</xsl:stylesheet>

The first template will get the first matched element in METADATA, the second
template will get the first in StringMap.
