DocumentFragment and DocumentWrapper

Added by Anonymous almost 20 years ago

Hi, I create a DocumentFragment, expecting to have it have 2 child elements which are the document element from 2 different documents, using: Node n = doc1.importNode(doc2.getDocumentElement(), true); DocumentFragment df = doc1.createDocumentFragment(); df.appendChild(doc1.getDocumentElement()); df.appendChild(n); DOMSource ds = new DOMSource(df); ... trans = tf.newTransformer(xsltStreamSource); trans.transform(ds, sr); And I get an error: java.lang.IllegalArgumentException: DocumentWrapper#wrap: supplied node does not belong to the wrapped DOM document. Am I expecting the wrong thing from importNode?

Sorry, but Saxon doesn't support a DOMSource that contains a DocumentFragment rather than a Document node as its root. Michael Kay

Well, this barely qualifies as a Saxon question, but I'll try. I want to merge n XML documents and be able to use the id() function in saxon 6.5.3, and I don't think I can move to JAXP 1.3. I've created a SAX XMLFilter that merges XML documents one of which, in my test, uses an XML schema. While Xerces does validate the document, it doesn't create SAX attributes for IDs as type ID, it creates them as type CDATA.... So, what is a good way to merge n documents while preserving IDs (assuming there will never be a conflict between IDs), or otherwise allowing XSLT to use id()?

I should add that the id attributes are declared as IDs. Xerces complains if there are duplicate IDs, for example. Also, I should point out that I want to use id() not key().

If you're feeding SAX events into Saxon to provide the transformation input, then presumably you have control over the attribute type supplied in the Attributes object. If you set it to "ID", then Saxon will recognize the value as an ID for the purposes of the id() function. On the other hand, it might be a lot simpler to use the key() function instead of the id() function. Michael Kay

Okay. But I can't tell if the attribute was type ID in the schema from inside the ContentHandler because the parser is telling me it is of type CDATA, unless I use prior knowledge of the document to match attribute names, which I don't want to do. Arghh...

Okay, if anyone cares. Xerces 2.6.2 supports PSVIProvider, so I can cast it's XMLReader (not SAXParser as it's docs say) into a PSVIProvider and then get type information inside startElement() in the ContentHandler part of my XMLFilter.
