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 "anincludedfile 1.xml">
<!ENTITY anincludedfile2 SYSTEM "anincludedfile 2.xml">
]>
<arootnode>
&anincludedfile 1;
&anincludedfile 2;
</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]).

ruminations on #include and paths

One thing that can make porting C code from one platform to another miserable is #include. In particular, the need to either place the path to an included file within the #include statement or to very carefully define the order in which paths are searched with command line options on the compiler. Both can cause problems, especially when dealing with complex software distributions. It occurs ot me that by extending the C include...
