hi everyone!
i'm trying to write a branching recursive function, but i have a problem
with the "xsl:sequence" being non-terminating.
how can i get the following to work:
<xsl:function name="r2c:hasTextContent" as="xs:boolean">
<xsl:param name="node"/>
<xsl:for-each select="$node/*">
<xsl:choose>
<!--ignore!-->
<xsl:when test="r2c:isOutputNode(.)"/>
<!--gotcha!-->
<xsl:when test="r2c:isLeafNode(.)">
<xsl:value-of select="true()"/>
</xsl:when>
<xsl:otherwise>
<!-- recurse into the current node -->
<xsl:sequence select="r2c:hasTextContent(.)"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
<!-- no leafNodes found?:-->
<xsl:sequence select="false()"/>
</xsl:function>
this will inevitably put more than one boolean into my output sequence,
which will cause an error.
iiuc, either i need a re-settable variable (which xsl does not have), or
a way to terminate the function after each xsl:sequence. i found
references to xsl:result, but it seems to have gone the way of the dodo...
any hints?
