Greetings community of pharo

I have to process many XML files, to convert them to objects and incorporate them into a database and create an application in seaside.

In pharo I have found XmlParser, however I have not found documentation to use it as best as possible.
I do not know if there is another more appropriate tool. Please if possible and there are examples of common use of xml processing inform me.

Thank you very much in advance
Oswall
