Apply XSLT to an XML file

Question

I realise that I will probably regret asking about this for the rest of my life, but... Is there some way of applying XSLT to an XML file without the XML file havin

Answer 1

Responding to the OP's edit requirement to pick different XSLTs from the browser.

I didn't do any investigating before answering, but way back when IE was the only practical game in town, I remember there was a default CSS that got applied to XML files in the browser. Since CSS and XSLT files are specified in documents with a processing instruction, might there be some way through plugins/extensions to arbitrarily override the browser's default stylesheet - assuming other browsers handle this in a similar way?

Or might there be a way to dynamically add the processing instruction to the document and refresh?
