[saxon] java setParameter() on transformer

[Marc Pellmann]

Hello!

I want to set an XML struktur as a parameter for an xsl tranformation
with saxon. I have read in an old mail from Michael Kay, that this
should work with a w3c Document. But it does not work for me.. the
result is [#document: null]. (In the script I do a copy-of of the param)

I actually understand that you are doing something like:

<xsl:param name="xmlstructure" />

<xsl:template match="whatever">
<xsl:copy-of select="$xmlstructure" />
</xsl:template>

and when applying the stylesheet to some xml-document, you pass a value
for "xmlstructure" like this one:

transformer.setParameter("xmlstructure", "<test><subelement>this is a
test</subelement></test>");

I think (although I must admit that I never used it myself) that it should
be possible to parse the parameter into xml-nodes with
saxon:parse(...)

The rules for converting Java objects supplied as stylesheet parameters are
described here:
<http://www.saxonica.com/documentation/extensibility/function-result.html>

It is not mentioned on that page but I think you may need to have
saxon8-dom.jar on your classpath for the DOM Node (including Document) case
to work.

Thank you - I now use a javax.xml.transform.Source instance and it works
well!

BTW Michael, this page says (the second and last items on
the list resp.):

- If the method returns null, the XPath value is an
empty sequence.

- If the result is any other Java object (including
null), it is returned as a "wrapped Java object".

I don't understand why you precise "including null".
Don't you refer to the case in which a null is returned, so
it is converted to an empty sequence?
