Betreff: Re: [xsl] in search for more elegant XPaths


I very often testing for element nodes that have character content 
with *[string-length(normalize-space(.))>0]

No need to work out the length (which can be surprisingly costly for general 
unicode strings) you can just do

 *[normalize-space(.)]

as the predicate is true if teh string is non empty. (Although I have a feeling 
saxon for example does that rewrite for you anyway, so it may make no 
difference.)


      <xsl:text>

You haven't specified a return type for ypur fuction but if it's intended to be 
a string declaring it as as="xs:string" and using <xsl:sequence 
select="'sozial'"/> rather than <xsl:text>sozial</xsl:text> saves the cost of 
building a text node.

<xsl:function name="ln:getCaseType" as="xs:string>
        <xsl:param name="case" as="element()"/>
        <xsl:choose>
   <xsl:when test="matches(.,'^[LB]?SG')">
    <xsl:sequence select="'sozial'"/>
   </xsl:when>
   <xsl:when test="matches(.,'^[LB]?A(rb)?G')">
    <xsl:sequence select="'arbeit'"/>
   </xsl:when>

Those regex are a bit more lax than your tests but they need not be.

David
