Lab 9: Unwrap that <div>

In this folder is this XML document:

   - Chapter.xml

Open the document and inspect its content.

The content of <Chapter> is multiple <section>
elements.  Each <section> element contains a
<title> followed by a <section> (i.e. it's recursive)

I have wrapped one of the sections within a <div> element,
which is declared in div.rng

Write an NVDL script, Chapter.nvdl, which validates the
instance document.  The <div> element should be both
validated, and unwrapped.

After you have created the NVDL script, open a DOS window, change
directory (cd) to this folder, and then type: run

Remember: No News Is Good News!  If all you see after typing "run" is "Done" 
then there were no errors in your NVDL script.

Congratulations!  You have just implemented concurrent validation.
