after i create the xml file... how can i retrieve it and add some info to it... for example how can i add another page to chapter... or another chapter to book...any help would be greatly appreciated...

I think this code will add a chapter to your book.


There is also an insertBefore function you can use to insert the chapter before an existing chapter.

This will insert the new chapter before the 4th chapter.

There is one thing I don't like about the toprettyxml function. If you open a "pretty" xml document and prints it back to the file with toprettyxml, it adds the prettyfying whitespace one more time so you get twice as much whitespace as you want.
