Re: [xsl] Output common IDs

You don't really need to save the result of the first tokenize() call
to a variable, but you do need to tokenize on '\n', rather than '\t+',
in order to get each line in turn.  You'll also need to save the value
of each item in the outer for-each so you can access it in the inner
for-each.

Using normalize-space() before passing $FilteredPageIds to tokenize()
will get rid of the "blank" results caused by newlines at the start
and end of the text inside the "id" element.  This change will also
pretty much eliminate the need for the $CurrentPageId variable.
Finally, add a newline after printing each match.

    <xsl:template match="/AllIds">
        <xsl:for-each select="tokenize(text(),'\n')">
            <xsl:variable name="CurrentId" select="current()"/>
            <xsl:for-each
select="tokenize(normalize-space($FilteredPageIds),' ')">
                <xsl:if test="current() =
substring-before(normalize-space($CurrentId),' ')">
                    <xsl:value-of select="concat($CurrentId,'&#10;')"/>
                </xsl:if>
            </xsl:for-each>
        </xsl:for-each>
    </xsl:template>

Taking advantage of XSLT's abilities to match against sets and filter
the results of tokenize() with a predicate, we have the following
version.

    <xsl:template match="/AllIds">
        <xsl:variable name="PageIds"
select="tokenize(normalize-space($FilteredPageIds),' ')"/>
        <xsl:for-each
select="tokenize(text(),'\n')[substring-before(normalize-space(.),' ')
= $PageIds]">
            <xsl:value-of select="concat(.,'&#10;')"/>
        </xsl:for-each>
    </xsl:template>
