XIncluding chunks, XUpdating or XQuerying them later

[nestoru]

Hello guys,
I need to be able to include xml chunks from several
entity xml files
into a a master one that is supposed to be shown to
users.

Those users should be able to edit the final xml
file
but when doing
so they should be actually updating the chunks.

With an example:

books.xml
--------------
<books
<book isbn="foo" author="bar"/
.....
</books

bookstores.xml
---------------------
<bookstores
<bookstore
<book isbn="foo" author="bar"/
...........
</bookstore
</bookstores

libraries.xml
---------------------
<libraries
<library
<book isbn="foo" author="bar"/
...........
</library
</libraries
or <libraries

A given user updating now libraries realize the
author
for isbn "foo"
is not "bar" but "xar" so whenever he updates
libraries he should
actually be updating books.xml.

I am just trying to reuse any work already done
about
this problem. I
can use XInclude to get the books chunks into the
libraries and
bookstores files. I can use XSLT to present a pretty
form to the user
and then whenever the user hits submit for a change
I
can use XUpdate (Or if I decide let us say to host my xml files in an
eXist Native Database I could use its enhancement to XQuery)
if I maintain somewhere the XInclude rules just to
know what to update
but too much custom code for something that maybe is
already
integrated or easy to accomplish using oXigen XML solutions.

Generation of the GUI to edit should be done using a
W3C schema.

Could anyone point me to a good direction here?

Any help highly appeciated. Thanks to you all,
Nestor Urquiza

Hello,

<oXygen/> does not have such built-in support.

I can use XInclude to get the books chunks into the
libraries and
bookstores files. I can use XSLT to present a pretty
form to the user
and then whenever the user hits submit for a change
I
can use XUpdate (Or if I decide let us say to host my xml files in an

if I maintain somewhere the XInclude rules just to
know what to update

I think this is the support that <oXygen/> can offer in your case.
