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.
