Subject RE: Conditional assignment of tree frag to variable doesn't work.
Date Thu, 08 May 2003 19:20:44 GMT
The construct
<xsl:variable name="foo">
    <xsl:when test="whatever">
      <xsl:text>We have a whatever at this point.</xsl:text>
      <xsl:text>We don't have a whatever at this point.</xsl:text>
is part of our test suite, and it should work in all 2.x versions. Since
it creates an RTF, the variable is always "set", so a test for set-ness,
<xsl:when test="$foo != ''">
should always pass.

On the other hand, variables don't seem to pop out of xsl:choose as in
<xsl:template match="/">
    <xsl:when test="whatever">
      <xsl:variable name="foo" select="'have-whatever'">
due to the visibility rule (following siblings and descendants) in part
11.5 of the XSLT spec. Sorry about that.

I think Keith's problem might be about critical values being buried in
the RTF he created. My suggestion is to have a variable that is set to a
simple boolean (not RTF) that will be directly usable in later xsl:when
elements. <xsl:when test="$have-whatever">
