Subject: Re: [xsl] Identity transformation for XSLT 2.0 From: David Carlisle <davidc@xxxxxxxxx> Date: Mon, 17 Dec 2007 11:41:14 GMT |
> I think there are two use cases where keeping the entity references through > the transformation is a valid user requirement: Yes but usually (or often or sometimes) the way to achieve that is not to stop there expansion, but just to expand them, collapse them and then fold them up at the end. our NAG DTD which has a lot of (as in several thousand) entities each entity is of the form: <!ENTITY whatever '<start-entity xid="whatever"/> ..... <end-entity xid="whatever"/>"> when transforming, sometimes you let entities expand, sometimes you change &whatever; to [[[[amp]]]]whatever; to suppress expansion and sometimes you want to let it expand, then do the transformation, then replace wheaver is (now) between <start-entity xid="whatever"/> ..... <end-entity xid="whatever"/> replace it by &whatever; and make that the new definition of the entity (and worry about what to do if different instances of the entity reference got transformed to different things. There's no universal right answer, so it's hard to sell (or even give away:-) an "improved" identity transformation that "fixes" the problem.
