You should start by reading the Database section of Tutorials, where you will find how to use DBI, the library you need to interface with databases. I suggest to use Class::DBI to make your life easier. If you are also looking for a dbms that works on *nix and other OSs, try with MySQL.

Ciao, Valerio

This is capable of interfacing with most, if not all, database systems, and will allow you to perform SQL queries, and retrieve results from the database server.

I do not want to use mysql or other databases

We really need more infomation on what it is you are trying to do. You did mention XML files.

• Are you trying to get info from xml files into a database?
• What database "are you using"/"have you experience with"?
• Are there more than one xml files, and you need to get the info from ALL of them into the database?
• Who controls the xml file/s?
• Do you only need to read the files into memory and then do something with the data later in your script?

As you can see there are loads of questions that still need to be answered before we can give you any really meaningful help.

Take a look at DBD::SQLite. Works on both Windows and Unix, doesn't require anything else installed and does support fairly complete SQL.
