Or maybe the Tag and Script interfaces could just be extended by a getXML()
method. In the case of a Tag an Element would be reeturned, and in the case
of a Script maybe a List. Or is there a notion of XML fragments in dom4j?
Then the <xu:expected/> and <xu:actual/> could do something like this:
AssertDocumentsEqualTag assertTag =
(AssertDocumentsEqualTag)
findAncestorWithClass(AssertDocumentsEqualTag.class);
if (evalBody) {
SAXContentHandler handler = new SAXContentHandler();
XMLOutput newOutput = new XMLOutput(handler);
handler.startDocument();
invokeBody(newOutput);
handler.endDocument();
assertTag.setExpected(handler.getDocument());
} else {
assertTag.setExpected(createDocument(getBody().getXML()));
}
(Note the createDocument() which would have to be implemented.)
This would of course require Tags and Scripts to store their serialized XML
form.
How do you feel about this idea?
