Include an xml file into another

[jmcmejl]

Hi
I have a question regarding including an xml file into another.
I have googled and found this:

Mainfile.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE adocname[
<!ENTITY anincludedfile1 SYSTEM "anincludedfile1.xml">
<!ENTITY anincludedfile2 SYSTEM "anincludedfile2.xml">
]>
<arootnode>
&anincludedfile1;
&anincludedfile2;
</arootnode>

anincludedfile1.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<anode name="test1" />

anincludedfile2.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<anode name="test2" />
So far noproblem, everything works great.

But here is my problem, I would like anincludedfile1.xml to include
another xmlfile and that file might include another ant so forth.
In reallity I will probably not be very many levels but I would prefer
not having any limitations.
Applying the same technique on the other files will render an error
somethng like "You can only have one doctype".

Please help me.
/Jimmy

I don't think you can solve that with external entities. Also note that
external entities are not read by non validating parsers so for instance
if you loaded your Mainfile.xml in a browser like Mozilla which uses the
Expat parser it would not load the external entities at all.

XInclude <http://www.w3.org/TR/xinclude/might do what you want in
terms of levels but it is a new specification and has not much support
either. So unless you know you are going to process your Mainfile.xml
with a certain parser that supports XInclude there is not much use in
applying it as lots of XML parsers/tools others might use to process
your XML will not process XInclude instructions.

Files included by this method must not have their own DocType
Declaration (XML Spec, section 4.3.2, production [78]).
