I want to read in multiple XML documents and build a main nodeset. The number of xml documents is unknown, but can be passed in as a comman delimited list within a parameter:

<xsl:param name="docs"/>
<xsl:variable name="docSequence" select="tokenize($docs, ',')"/>

Can I then build a variable that includes all document nodesets using:

<xsl:variable name="mainNodeset">
  <xsl:for-each select="document($docSequence)">
     <xsl:copy-of select="."/>
  </xsl:for-each>
</xsl:variable>

I think I have the logic turned around a bit how to loop thru the tokenized list. Any help is greatly appreciated.

Is there a better way to work with a unknown number of input documents?

Also, I am curious about performance impact as a result of storing the nodesets as a variable and working from that variable instead of an XML file.

Thanks.

Actually, all you need is

<xsl:variable name="mainNodeset" select="document($docSequence)"/>

since document() in 2.0 accepts a sequence of strings as its input.

Thanks. Even easier.
