AW: [xsl] How to return values from sub-template?

["Huditsch Roman" <Roman.Huditsch@xxxxxxxxxxxxx>]

I think it should be sufficient to use

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
	<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
	<xsl:template match="/">
		Age exists=
		<xsl:call-template name="subtemp">
			<xsl:with-param name="parm" select="//myelement[@name = 'karl']"/>
		</xsl:call-template>
	</xsl:template>
	<xsl:template name="subtemp">
		<xsl:param name="parm"/>
		<xsl:value-of select="exists(@age)"/>
	</xsl:template>
</xsl:stylesheet>

since the return value of a named template is inserted in the place,
where you call your named template.

Alternativly you can also put your named template call in a variable,
which then gets the returned value assignd.

BTW, exit() should be exists()...

wbr,
Roman
