Re: Output common IDs

I think (perhaps) you've made the common mistake of imagining that
contains() tests whether a particular sequence contains a particular
value. In fact, contains() does something quite different - it tests
whether a string contains a substring.
To test whether a sequence $S contains the value $V, just use the "="
operator - ($S = $V).
In fact this problem seems to be much simpler than you are making it: I
think it's just
<xsl:template match="/AllIds">
<xsl:value-of select="tokenize(., '\s+')[. = tokenize(doc('PageIDs.xml')/id, '\s+')]"/>
</xsl:template>

Hi,
I have a xml file (PageIDs.xml) which contains several IDs. I have
another file which contains ID and URI separated by a tab(AllIDs.xml)
The question is, For each tokenized ID contained in PageIDs.xml file I
want to test all IDs in AllIDs.xml and if ID test matches output
matching line as text. This is simple for members in the list, I tried
but I could not solve this using XSLT 2.0
PageIDs.xml

AllIDs.xml

<AllIds>

</AllIds>
This is the XSLT I've written...
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs" version="2.0">
<xsl:output method="text"/>
<xsl:variable name="FilteredPageIds" select="doc('pageIDs.xml')/id"/>
<xsl:template match="/AllIds">
<xsl:variable name="AllListedIds" select="tokenize(text(),'\t+')"/>
<xsl:for-each select="$AllListedIds">
<xsl:for-each select="tokenize($FilteredPageIds,'\n')">
<xsl:variable name="CurrentPageId"
select="normalize-space(current())"/>
<xsl:if test="contains($CurrentPageId, $AllListedIds)">
<xsl:value-of select="$AllListedIds"/>
</xsl:if>
</xsl:for-each>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
This fails at contains because the item is a collection and I am not
sure how to handle them.
Expected output for IDs matching in PageIDs.xml,
