Adding a localization to an “Extension Builder” generated TYPO3 extbase extension could be a little tricky as it uses the xlf (XLIFF) format.

This is a simple way to add new localizations without using extra tools like Virtaal or a Pootle server.

1. copy file and prefix filename with language coed: example.xlf to de.example.xlf
2. add target-language=”de” attribute to node file
3. change source nodes to target

Please make sure…
your files are UTF8 encoded
to encapsulate special chars in CDATA
