RE: [xsl] key from one file to another set of files

["Michael Kay" <mike@xxxxxxxxxxxx>]

The key() function searches the document containing the context node, unless
you supply a third argument, in which case it searches the document (or
subtree) identified in the third argument. You want

<xsl:template match="/" name="main">
  <xsl:variable name="index" select="."/>

   ... then ...

  <xsl:if test="key('order', '$a/article/item-info/aid', $index)">

Except that you don't only want to test whether the article exists, you want
to find the right row, and use it when you do

<page>
<xsl:value-of select="document('input.xml')/articles/row/col[3]"/>
</page> 

because that is otherwise going to give you the third column of every row.
