Parsing two XML files at the same time

Hi,

I have 2 XML documents. One is my master that has all the articles and the other with only the article ids for the articles that I need to select from the first XML.

So, I am in the first XML, do some processing, write the IDs in the 2nd XML. Then I open 2nd XML, read the ID and now I want to go back to first XML, find the matching articles and list the descriptions for those. Any help is greatly appreciated.

Here's the code:

<xsl:apply-templates select="content/article" mode="details" />

<xsl:template match="article" mode="details">
<!-- c:\article_index.xml is the 2nd XML that contains only indices -->
<xsl:apply-templates select="document('c:\article_index.xml')" mode="proc-id"/>
</xsl:template>

<xsl:template match="//ID" mode="proc-id">
<xsl:variable name="articleid" select="." />
<xsl:value-of select="$articleid"/>
<!-- it works upto here. It gets the right id from 2nd file, but since it's pointing to 2nd XML, it does not now recognize string(content/id) from the next statement which should be from the 1st XML file --->
<xsl:value-of select="string(content/id/.)"/>
<xsl:when test="number(content/id/.) = $articleid" >
<xsl:text> </xsl:text>&#160;
<xsl:value-of select="string(normalize-space(content/title/.))"/>&#160;
<xsl:call-template name="strip-tags">
<xsl:with-param name="teaser" select="normalize-space(content/teaser/.)"/>
</xsl:call-template>
..........


The format for 2nd XML is 
<article>
  <id>1</id>
  <id>2</id>
</article>


Thanks
