New to Java

Hello there people
I have recently completed a program for parsing XML files and putting their information in a database.

Although I am new to the XBRL Format (eXtensible Buisness Reporting Language) I am wondering about a few things.

1) If XBRL documents are simply fancy versions of XML files, then parsing an XBRL should be as simple (and hopefully the same process as) parsing a regular XML file.

2) For my original parsing program, I have chosen to create a Document Object Model instance which I can then navagate the tree-like structure and do things with its contents. My question is, is there any kind of projects out there specifically designed for XBRL activities in JAVA. Things like parsing, creation or whatever.
