Storing XML docs in SQL DB?

Hello SuSE folkz, Does somebody know about possible solution to store XML formatted documents in SQL DB on Linux? Our company is in need for document storage server. We have Linux server with MySQL DB server and set of Perl applications and FCGI scripts to collect, analyze and plot engineering and process data right in a browser window. I think, that it's a good idea to store pre-formatted XML documents right in DB. The question is how to format and manage sich a collection of documents. Mickysoft has some XML documents management system. Is there something similar in Linux world? Thank you in advance for any ideas or sources of information. Alex
