Is it possible to change content of a commit by pre-commit hook?

Hi all

We export PowerCenter workflows as XML to commit those to subversion. We would like to make sure that the description attribute of the tags contain subversion information like Rev or Header. Is it possible to change the content i.e. the value of the xml description attribute by commit hook? I had a look at red bean book and search the net for hints. I only found 'svnlook cat' to echo the content of the file but I did not find a means to alter the content. Is it possible to achieve or do I need to make a check on the content and fail the commit if the required bits of information in the content is not present?

Kind regards
