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.
