Test on child elements - alternative?

[Phil Jenkins]

Hello there

I've inherited some code, which looks like this:

<!-- recreate the element (with its namespace) -->
<xsl:element name="{local-name()}" namespace="{namespace-uri()}">

<!-- if it has children... -->
<xsl:if test=".//">
<!-- process the children -->
<xsl:apply-templates/>
</xsl:if>
<!-- if it does not have children... -->
<xsl:if test="not(.//)">
<!-- recreate its value -->
<xsl:value-of select="."/>
</xsl:if>
</xsl:element>

Which seems to be a long winded <xsl:copy of> method - but the
important part is that the test for children -> ".//" no longer works
with a newer version of xerces - i'm getting an error along the lines
of "a location step was expected after the //".

So the question is - is there another more correct way of testing for
children right down the node tree, i'm sure there is but i'm stumped
with my limited xslt experience.

Thanks in advance

Replace ".//" with ".//*" and see if that helps.

Hi Wim

Thanks for that - the error has stopped, but the template match doesn't
exhibit the same behaviour - anything that isn't a child element (i.e
text) is being replicated twice.

<element>Text</element> would come out as TextText.

Thanks for your help so far

For anyone interested - the error was due to upgrading from Xalan 2.3
to 2.7, where the XPath '//' statement has been replaced with the more
correct /descendant-or-self::node()
