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

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?

Could somebody help me on this issue? I am having a
problem assingning values to a variable. Look the example:
-------------------------------------------- These ones were declared globally:
<xsl:variable name="teste" select="'um'"/> <xsl:variable name="um" select="'um'"/> <xsl:variable name="dois" select="'dois'"/> --------------------------------------------
-------------------------------------------- This code was declared inside a template:
<xsl:choose>
<xsl:when test="$teste = 'um'">
<xsl:variable name="teste"><xsl:value-of select="$dois"/></xsl:variable>
</xsl:when>
<xsl:otherwise> <xsl:variable name="teste" select="$um"/> </xsl:otherwise>
</xsl:choose>
<font face="arial" size="3"><xsl:value-of select="$teste"/></font> --------------------------------------------
This code only returns me the value 'um'. The when
clause is working, but the assigning of value to the $teste variable is
no working inside the choose clause.
Could somebody please help me? Thank you very much!
