#modify_content(filename, new_basename, &blk) ⇒ Object

unzips the file, gives a string of the content xml and will replace it whatever you pass back (preferably a string;) requires write access to the directory where the file is located The next time you open the file, it will act like you’ve corrupted the file (the character count is probably off, etc) just let it clean it up for you! new_basename = base name of the new file (preferably <name>.odt)
