XSLT document format command tags not working with s9api?

Added by Allen Bagwell over 6 years ago

I'm using Saxon-EE 9.6.0.8 and have encountered an odd issue.

In the past I've mapped the javax.xml.transform.TransformerFactory to the net.sf.saxon.TransformerFactoryImpl class for doing XSLT 2.0 transforms. Works perfect. Recently however I attempted to do a complete s9api approach to setting up the transformer. This also worked, but the formatting output ignored the settings for:

<xsl:output ident="no" omit-xml-declaration="no"> <xsl:strip-space elements="*">

That is when I ran my XSLT 2.0 stylesheet using the javax mapping and classes, the entire output document was all on a single line starting with the XML declaration element. When I changed the invocation to use the s9api classes the exact same stylesheet produced formatted XML output (line breaks and indents) and the declaration element was missing. I even tweaked it to run as a 3.0 stylesheet, but it behaved the same way.

Is there something about using the s9api that requires more than the stylesheet output commands to get what I want?

Thanks! Allen

How did you set up the transformation destination?

I used

XdmDestination dest = new XdmDestination(); transformer.setDestination(dest);

...

transformer.transform(); String output = dest.getXdmNode().toString();

An XdmDestination is just a tree in memory. When you serialize that tree using dest.getXdmNode().toString() the serialization performed by the toString() method has no knowledge of the xsl:output parameters in the stylesheet. You need to send the output of the transformation to a Serializer; the transformer and serializer will communicate with each other to decide which serialization parameters to use.

Ah, of course. That makes sense. Just didn't think it through. It's working now.

Thanks, Michael! :)
