[xsl] comparing strings
Subject: [xsl] comparing strings From: Oliver Becker <obecker@xxxxxxxxxxxxxxxxxxxxxxx> Date: Tue, 2 Jan 2001 10:28:29 +0100 (MET) |
Dear friends, happy new year to everybody! Is there someone out there who can answer my simple question: How to compare strings with XPath/XSLT, something like strcmp() in C or compareTo() in Java? I want a pure XSLT solution without using extensions. For those of you who are interested I have a little use case: Consider this simplified dictionary: <longman> ... <term>oz</term> <term>ozone</term> <term>p</term> <term>pa</term> <term>pace</term> <term>pacemaker</term> <term>pacesetter</term> <term>pachyderm</term> <term>pacific</term> <term>pacifier</term> <term>pacifism</term> <term>pacifist</term> <term>pacify</term> <term>pack</term> <term>package</term> <term>packaged</term> <term>packaging</term> <term>packed</term> <term>packer</term> <term>packet</term> <term>packing</term> <term>pact</term> <term>pad</term> ... </longman> Question: given an arbitrary input term (e.g. as a parameter), how can I display the next 10 terms, starting with my input or the term which would follow directly in alphabetical order? If I had numbers instead of strings, the following template would solve the required task: <xsl:param name="input" /> <xsl:template match="term"> <xsl:if test=". >= $input and not(preceding-sibling::term[10] >= $input)"> <!-- display . in some appropriate way --> </xsl:if> </xsl:template> Regards, Oliver /-------------------------------------------------------------------\ | ob|do Dipl.Inf.
