Re: [xsl] Assigning variable values

[Joerg Heinicke <joerg.heinicke@xxxxxx>]

Hello Georges,

the variable got out of scope, if you declare them in <xsl:when/>. You 
have to turn around the XSL-elements:

<xsl:variable name="teste" select="'um'"/>
<xsl:variable name="um" select="'um'"/>
<xsl:variable name="dois" select="'dois'"/>

<xsl:template match="/">
    <xsl:variable name="teste">
      <xsl:choose>
          <xsl:when test="$teste='um'">
            <xsl:value-of select="$dois"/>
          </xsl:when>
          <xsl:otherwise>
            <xsl:value-of select="$um"/>
          </xsl:otherwise>
      </xsl:choose>
    </xsl:variable>
    <xsl:value-of select="$teste"/>
</xsl:template>

But I don't know whether you know that variables can't be re-assigned. 
So in the global variable there is still stored 'um', only in the local 
one the value is 'dois'. This behaviour can be reproduced with MSXML. 
With Xalan it's not possible. You will get an error "Variable accessed 
before it is bound!" I think that's not the correct behaviour, is it?
