Ah, BTW, if you need something that runs under an older Python version (I
assume you want it to run in OOo), here's a solution that also runs with
ElementTree (which can be installed on Python 1.5 and later). lxml requires at
least Python 2.3.

   >>> import elementtree.ElementTree as et
   >>> TBNS = "{http://openoffice.org/2001/toolbar}"
   >>> tree = et.parse("myfile.xml")
   >>> for tbitem in tree.getiterator(TBNS+"toolbaritem"):
   ...     if tbitem.get(TBNS+"visible") == "false":
   ...         tbitem.set(TBNS+"visible", "true")


Have fun,
Stefan
