Thank you so much, David,

Your code helps me understand what I was writing wrong (or redundantly).

As it is now, the following code outputs the langSet for Spanish only:

	<langSet lang="spa-es"><ntig><termGrp>
	 <xsl:for-each  select="$t">
	  <xsl:copy-of select="."/>
	  <xsl:copy-of select="../termNote"/>>
	  <xsl:copy-of select="../date"/>>
	 </xsl:for-each>

but ideally it should output the langSet for any language, so I tried replacing the code above with

               <xsl:for-each select="langSet">
                  <xsl:copy-of select="current()"/>
               </xsl:for-each>

The result seems to be good contents-wise, with the langSet for all the languages. However, the format is akward, with one blank line between every two lines of contents, what makes me thing that perhaps there's somethign wrong. Any suggestion for improvmenet?

Thank you very much!!
Manuel

PS The full template would be like this now:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:key name="spa-term"
match="text/body/termEntry/langSet[@lang='spa-es']/ntig/termGrp/term"
use="."/>
<xsl:template match="/">
<martif type="Part2v1" lang="en">
<martifHeader>

</fileDesc>
</martifHeader>
<text>
<body>
<xsl:for-each select="martif/text/body/termEntry">
<xsl:variable name="t" select="langSet[@lang='spa-es']/ntig/termGrp/term
[generate-id(.) = generate-id(key('spa-term', .)[1])]"/>
<xsl:if test="$t">
<termEntry id="{@id}">
<xsl:for-each select="note|date">
<xsl:copy-of select="current()"/>
</xsl:for-each>
<xsl:for-each select="langSet">

</xsl:for-each>
</termEntry>
</xsl:if>
</xsl:for-each> </body>
</text>
</martif>
</xsl:template>
</xsl:stylesheet>



David Carlisle escribis: 
Just move the if test up before you create the outer element.
ehile I was there I simplified mist of the other code which seemed to be
more verbose than needed,


<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:key name="spa-term" match="text/body/termEntry/langSet[@lang='spa-es']/ntig/termGrp/term" use="."/>
<xsl:template match="/">
<martif type="TBX" xml:lang="en">
<martifHeader>
<fileDesc>
<sourceDesc>
<p></p>
</sourceDesc>
</fileDesc>
</martifHeader>
<text>
<body>
<xsl:for-each select="martif/text/body/termEntry">
<xsl:variable name="t" select="langSet[@lang='spa-es']/ntig/termGrp/term
[generate-id(.) = generate-id(key('spa-term', .)[1])]"/>
<xsl:if test="$t">
<termEntry id="{@id}">
<langSet lang="spa-es"><ntig><termGrp>
<xsl:for-each select="$t">
<xsl:copy-of select="."/>
<xsl:copy-of select="../termNote"/>>
<xsl:copy-of select="../date"/>>
</xsl:for-each>
</termGrp>
</ntig>
</langSet> </termEntry>
</xsl:if>
</xsl:for-each>
</body>
</text>
</martif>
</xsl:template>
</xsl:stylesheet>
