Hi !
I have a function which takes an element as parameter.
I want to validate this element against an xsd schema type definition.
I'm using XSLT 3.0 with a schema aware processor (SaxonEE 9.7.0.15)
At first, I thought I only have to :
<xsl:import-schema schema-location="my-schema.xsd"/>
And then type the parameter:
<xsl:param name="e" as=" schema-element(my:element)"/>
But it does not validate (when the xml in not valid I don't get any errors or
warnings)
Then after reading the XSLT 3.0 spec, I realized validation is processed only
on source or result-tree:
"The imported type definitions can be used for temporary nodes or for nodes on
a result tree just as much as for nodes in source documents"
So I found this solution :
<xsl:import-schema schema-location="my-schema.xsd"/>
<xsl:function name="my:function">
<xsl:param name="e" as="element()"/>
<xsl:variable name="e" as="document-node(schema-element(my:element))">
<xsl:document validation="strict">
<xsl:sequence select="$e"/>
</xsl:document>
</xsl:variable>
... do something here
</xsl:function>
This works pretty well, I actualy get a fatal error with its description when
$e is not valid, which is exactly what I was looking for.
Any advices, comment on this, is it a good way to do ? or there is something
more obvious which I missed (preventing creating this document-node for
example?)
Thanks in advance,
Cheers
Matthieu
