Are you sure you need this to be done with bash? XML parsing requires significant text processing which is not at all well suited to bash. Even using a programming language that is much stronger at text processing, such as Perl, it is not recommended to process XML without the aid of a known-good library such as XML::Parser or other similar package.

Some you could check out is XMLStarlet at http://xmlstar.sourceforge.net/.
