Hi Isaac

I have xml that looks something like this:

> Exhibit A. --before
> (many other irrelevent records)...
> <nodeA att1="True" att2="N" att3="1234"/>
> <nodeA att1="True" att2="N" att3="321"/>
> <nodeA att1="True" att2="N" att3="456"/>
> <nodeA att1="True" att2="Y" att3="9876"/>
> <nodeB att1="True" att5="Y" att3="45"/>
> <nodeB att1="True" att5="N" att3="65"/>
> <nodeC att1="True" att7="Y" att3="784"/>
> <nodeC att1="True" att7="Y" att3="412"/>
> <nodeC att1="True" att7="N" att3="635"/>
> ...(many other irrelevent records)

Why not use a key:

<xsl:key name="getNodes" match="nodeA|nodeB|nodeC" use="@*"/>

Then all you need to do is:

<xsl:copy-of select="key('getNodes','N')"/>
<xsl:copy-of select="key('getNodes','Y')"/>

Cheers
