Sorry for this newbie question but I didn't found a hint in tutorials on
how to return
back parameter values from sub-templates. Assume the following situation.
I want to pass back the boolean (or other values in other scenarios)
value if the attribute "age"
exists in a node "myelement" with the attribute name="karl".
Yes, I know, THIS sample could be coded easier within
one template but my sample is only a simplified version for a complex
scenario
where two templates are required.
Again, how can I access the value of the variable myval from the calling
template?
You can't because its created inside the template "subtemp" and in its
context.
Thank you
Matt
<xsl:template match="/">
<xsl:call-template name="subtemp">
<xsl:with-param name="parm" select="//myelement[(_at_)name = 'karl']" />
</xsl:call-template>
Age exists=<xsl:value-of select="$myval" /> <!-- does not work -->
</xsl:template>
<xsl:template name="subtemp">
<xsl:param name="parm" />
Hello
<xsl:variable name="myval" select="exist(@age)" />
return $myval
</xsl:template>
Just don't use an xsl:variable, return the value directly in the
template:
<xsl:template name="subtemp">
<xsl:param name="parm" />
Hello <!-- ? -->
<xsl:value-of select="exist($parm/@age)" />
</xsl:template>
Richard.
