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>
Use xsl:sequence here! xsl:value-of creates a text node. You're converting a
boolean to a string, wrapping the string in a text node, then because an
xs:boolean is required, the text node is atomized, and the string "true" is
converted back to a boolean.
<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.
Only if there is more than one leaf node.
Any hints?
Try:
<xsl:function name="r2c:hasTextContent()" as="xs:boolean">
<xsl:param name="node" as="node()"/>
<xsl:sequence select="some $x in $node/*[not(r2c:isOutputNode(.)]
satisfies
(r2c.isLeafNode($x) or r2c.hasTextContent($x))"/>
</xsl:function>
