RE: problems with variable - variables are only visible when scop ed

[Didier VILLEVALOIS <dv...@techmetrix.net>]

Can't we put xsl:choose inside xsl:variable ? Something like this :

<xsl:variable name="title">
  <xsl:choose>
    <xsl:when test="language[. = d]">Arhhh Nein!!</xsl:when>
    <xsl:when test="language[. = e]">Ohh No!!</xsl:when>
    <xsl:otherwise>Bah Si!!</xsl:otherwise>
  <xsl:choose>
</xsl:variable>

<xsl:copy-of select="$title"/>

I don't know if it works...
Didier.

(Ok, that wasn't a great Subject line, haven't had my morning coffee yet
8-)

This is correct behavior.  See:  http://www.w3.org/TR/xslt#local-variables
which details how variables are scoped (i.e. where a variable is visible
depending on where you declare it).  Basically your xsl:variable
declarations are only visible within the individual xsl:when statements,
and not outside of them.  Also, don't forget that you cannot re-bind or
re-set the value of a variable - they're more like constants.

Anyone else have a good suggestion for how to do something like this?  This
is a fairly common question, there might be other ideas in the mailing list
archive at  http://xml-archive.webweaving.org/xml-archive-xalan/
