Re: How to get to the XML Declaration

How can I read the values of the attributes of the XML Declaration in the
input document using XSLT and XPath?

You can't access the values of the attributes of the XML Declaration
using XSLT/XPath with standard functionality, for multiple reasons.
Your favorite XSLT processor might provide extension functions for
accessing these values. Check the docs.

Let us say I want to transform 100 documents with the same XSLT stylesheet,
and I want to treat them differently based on what encoding they use in
their XML Declaration.

On this list, this will solicit comments like "the mose grotesque use
case for several weeks". One of the major points of using XML is that
the consumer application doesn't have to worry about the encoding of
the source document.
