RE: [xsl] Scope of Local Variables?

["Rajput, Ashish S" <ashish dot s dot rajput at lmco dot com>]

Joerg, I apologize for my typo... the latter was meant to be a <xsl:template
match="data"> not a <xsl:template match="read">  I want to call the
variables within the "data" template.  Below is the corrected
translation.......


<xsl:template match="read">
	<xsl:variable name="rowTag"
select="./tagToAxis[./@axisIDRef='rows']/@tag"></xsl:variable>	
	<xsl:variable name="columnTag"
select="./tagToAxis[./@axisIDRef='columns']/@tag"></xsl:variable>
</xsl:template>

<xsl:template match="data">
	<xsl:value-of select='$rowTag'></xsl:value-of>
	<xsl:value-of select='$columnTag'></xsl:value-of>
</xsl:template>

Hello Ashish,

why do you have two templates matching on "read"? Change it to:

<xsl:template match="read">
   <xsl:variable name="rowTag" select="tagToAxis[@axisIDRef='rows']/@tag"/>

   <xsl:variable name="columnTag" 
select="tagToAxis[@axisIDRef='columns']/@tag"/>
   <xsl:value-of select='$rowTag'/>
   <xsl:value-of select='$columnTag'/>
</xsl:template>
