Subject: Re: [xsl] Return structured java Object (e.g. List) to XSLT for further processing From: "Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Mon, 15 Dec 2014 11:16:04 -0000 |
This question is very Saxon-specific. In future, I would suggest using a Saxon-specific forum, e.g. saxonica.plan.io. > > public Object footnote(Object nr, Object html) { } > > I can cast the nr (which is //footnote/@nr) and html (which is //footnote/*) to SequenceExtent. You can't rely on them being supplied as instances of SequenceExtent. For example, if the value is a singleton or an empty sequence (or in future releases) a different class might be used. Better to declare the argument types as net.sf.saxon.om.Sequence, and make no assumptions beyond them being a Sequence. > > Now I can process the footnotes. > > As result I want to return the processed footnotes, so that they can be processed by xsl as an result tree fragment. > > Rather depends how you are constructing them. It might be easiest to use a tree model that's designed for manipulation in Java, e.g. JDOM2, and then return a JDOM2 DocumentWrapper. If you want to construct a Saxon tree, you can instantiate a Builder and then feed it startElement() and endElement() events, but that's not especially convenient. Ultimately, though, you want to return an instance of the class DocumentInfo. Michael Kay Saxonica
