Sorry for my precipitation in asking my last question. What I though
that were the same problem, finally they were different problems.
I have resolved the problem with the images (that is the example
I sent previously): In xslt exists the funtion
string unparsed-entity-uri(string)
that returns the URI of the unparsed entity with the specified name.
I still have a problem with the use of a xslt stylesheet and a
xml document that include other xml subdocuments declared as
unparsed entity.
In the book "Structuring XML Documents" is recommended that when
you want to include a subdocuments in a xml document you should
the following scheme
- First, declare a notantio for the XML documents
<!NOTATION XML SYSTEM "http://www.w3.org/XML/";>
- Second, declare an NDATA entity for each subdocuments
<!ENTITY chap01 SYSTEM "chap01.xml" NDATA XML>
<!ENTITY chap02 SYSTEM "chap02.xml" NDATA XML>
- Third, declare an element type (usually empty) with an
ENTITY attribute to act as a placeholder for the subdocuments
<!ELEMENT chapter-ptr EMPTY>
<!ATTLIST chapter-ptr source ENTITY #REQUIRED>
So, now in the document you should put something like this
<body>
<chapter-ptr source="chap01"/>
<chapter-ptr source="chap02"/>
</body>
Using this scheme each subdocument can have his own DOCTYPE declaration.
The problem is that when I use a browser (IE or mozilla) to visualice
the document with his associated XSLT stylehseet, it does not
include the subdocuments. I want to know if this is the supposed
way of operation for an XSLT transformation motor, if so how can
access to the content of the subdocuments? and how can apply the
stylesheet of the main document? Another question arise, if I use
that scheme of including subdocuments, Does the browser validate
the subdocuments? if so what DTD it use the DTD of the main
document or the DTDs of the subdocuments?

: I want to know if using a XSLT stylesheet is possible to access
: to the information associated to a entity. I explain it using
: an example:
:
: I have a document like this:
:
: <?xml version="1.0"?>
: <!DOCTYPE root [
: <!NOTATION GIF PUBLIC "+//ISBN 0-7923-1::Graphic Notation//NOTATION
: Microsoft Windows bitmap//EN">
: <!ELEMENT root (include, txt)>
: <!ELEMENT txt (#PCDATA)>
: <!ELEMENT include EMPTY>
: <!ATTLIST include ref ENTITY>
: <!ENTITY mygif SYSTEM "draw.gif" NDATA GIF>
: ]>
:<root>
: <include ref="mygif"/>
: <txt>
: Some text
: </txt>
:</root>
:
:And I want that my stylesheet generates something like this
:
:<html>
:<head><title>A title</title></head>
:<body>
:<a img="draw.gif"/>
:Some text
:</body>
:</html>
:
:And for that I need to access to the name of the gif file
:("draw.gif" in the example) that is associated with the
:entity mygif.

:Thanks in advance
