Within my style sheet I need to be able to map between pairs of strings
(in this case, long and short titles).
I've tried to implement this by using an internal document-node() variable that defines the mapping and then using a function to do lookups against the map. The map looks like this (declared as a stylesheet-scope variable): <xsl:variable name="sectionTitleMap" as="document-node()">
<xsl:document>
<map>
<item>
<shorttitle>Background</shorttitle>
<longtitle>Overview and Background</longtitle>
</item>
<item>
<shorttitle>Scope</shorttitle>
<longtitle>Scope and Scope Exceptions</longtitle>
</item>
<item>
<shorttitle>Glossary</shorttitle>
<longtitle>Topical Definitions - Glossary</longtitle>
</item>
</map>
</xsl:document>
<xsl:variable>I then have this function to do lookups: <xsl:function name="func:getShortTitleForSection" as="xs:string"> <xsl:param as="xs:string" name="sectionBaseTitle"/> <xsl:choose> <xsl:when test="count($sectionTitleMap//longtitle[. = $sectionBaseTitle]) = 1"> <xsl:sequence select="$sectionTitleMap//item[longtitle[. = $sectionBaseTitle]]/shorttitle"/> </xsl:when> <xsl:otherwise> <xsl:sequence select="$sectionBaseTitle"/> </xsl:otherwise> </xsl:choose> </xsl:function> As far as I can see this should just work, assuming my input parameter occurs in the table. However, what I'm getting is that this works as expected for *some* input strings but not for others, where I've verified that the input strings match the values in the map. I must be doing something wrong but I can't figure out what it might be--the fact that some input values work and others don't is odd. Anyone have any idea what might be going wrong or what I can do to track down the bug? I've done things like copied a mapping target from my input document into the map just to be 100% sure the string is the same, but I still get the failure, so it doesn't appear to be something subtle like invisible characters in the input or some such (which I wouldn't expect in this case, but you never know). The real mapping is small enough I could rewrite the code to use choose/when for the mappings but this seemed like the most efficient way to do a two-way mapping in XSLT. Thanks, Eliot -- W.
