xml-dev - Nested XML files

[Usha_R2@verifone.com]

Hi! All,
   We can have a DTD as a collection of DTD files. Similarly, can a XML
file contain other xml files. 

Consider the following example:

--------file2.dtd---------

<!ELEMENT Y (#PCDATA)>

---------------------------

Now I use this in file1.dtd 

*********File1.dtd**********

<!ELEMENT file1 (X+ , Y)>
<!ELEMENT X (#PCDATA)>
<!ENTITY  % file2 SYSTEM "file2.dtd">
%file2;

*****************************

Defining File1.xml as follows:

---------------File1.xml--------------

<?xml version="1.0"?>
<!DOCTYPE file1 SYSTEM "file1.dtd">
<file1>
        <X>xyz</X>
        <Y>123</Y>
</file1>

-------------------------------------------

Now in File1.xml, I can have both "X" and "Y" elements. 

Can I use one xml file in another. For example instead of defining <Y>
element again in File1.xml, suppose if I have File2.xml as follows:

*******file2.xml***********

<Y>123</Y>

***************************

How do I use these in File1.xml again. Can I define an external entity
for an .xml file also. I tried this and it seems to be giving some
problems. Please let me know if its possible.


Thanks in advance
Usha
