Typo3 getting data and convert it to specific xml schema

i am new to typo3, so sorry, if this is too obvious. I do not expect a complete solution, just the topics i would need to read about in order to solve the task would be perfectly enough. :)

Here the task: I have a typo 3 installation with job advertisements in it. Now the company wants to publish that data in to a social website, which needs to have the job advertisement data put on a server in an xml feed, which looks like this: http://ift.tt/1sk594o. Don't worry about what it says in there, it's just stuff like Job Title, Description etc.

Like i said, i am completely new to this and just have a vague idea.

My thoughts so far were something like this:

• I probably need to write a plugin, which pulls the data out of typo3 by the push of a button


• That Plugin need to establish a database connection to pull the data (probably it's mysql, but i am not entirely sure yet)


• The data need to be formatted, which is either done by some string operations or by some kind of xml handler i assume.


• Sidenote: I read something about TypoScript, but i'd like to avoid that, since it's a one time project and probably not worth the time to learn it. For me at least.

Thank you loads for your help in advance.

Cheers
