Hi,
I don't understand exactly what is your question but if it is how to get a
magazine, you have to :
- parse your xml with digester.parse();
- this method returns a Catalog object for example "myCatalog"
- then call myCatalog.getMagazines() and find you magazine "mag1".
For example
for (Enumeration e = myCatalog.elements() ; e.hasMoreElements() ;) {
...
e.nextElement();
}

Perhaps you asked this in the wrong list. This list is for discussing
Tomcat issues. You can try at any XML/Java forums. Sun's Java forums
may be of help.
