RE: [xsl] Function to accept node and name of subnode in parameter strin

BTW I know about the typo in the parameter name and how it's used in the
function.

string


Hi all.  I need to create a 2.0 function that will accept an element()?
and a xs:string.  The string will contain the name of a subnode of the
first parameter.

The function will do something like this:

<!-- Given any node and the name of a subnode, returns 
     the nonempty subnode's value or N/A --> <xsl:function
name="fn:ValueOrNA" as="xs:string">
        <xsl:param name="node" as="element()?"/>
        <xsl:param name="childelementname" as="xs:string"/>
        <xsl:choose>
                <xsl:when test="$node and $node/$childname != ''">
                        <xsl:value-of select="$node/$childname"/>
                </xsl:when>
                <xsl:otherwise>
                        <xsl:value-of select="'N/A'"/>
                </xsl:otherwise>
        </xsl:choose>
</xsl:function>

But it always seems to return just the second string I pass in, not the
value of the subnode.

What's the right way to do this?

Thanks.
