Wanted: po file extract-merge script

[Francesco]

Hello Python- Ng,

I'm looking for a special script

(I don't want to reinvent the wheel; have anyone written such a thing?
I've looked in google (and groups), but I didn't find anything

it such one doesn't exist yet,
I will write it myself, or someone is so good to support me:))


I would call it pomerge.py
example
pomerge.py it_collection.p o my.po

I made a collection of strings, (i merged poedit po files and
wxwindows distribution po files into on)
BTW: Does there anyone exist a big collection file of all possible
strings?

(collection.po)
(I would extract msgid as keys and msgstr as values into a
dictionary.)

example (collection.pot )
msgid " Preview"
msgstr " Anteprima"

msgid "Envelope"
msgstr " busta"

msgid "&Close"
msgstr "&Chiudi"

.....


my.po
(filter out msgid's)

msgid "Exit"
msgstr ""

msgid "Envelope"
msgstr ""

msgid "Next"
msgstr ""


-----------

output should be:

msgid "Exit"
msgstr ""

msgid "Envelope"
msgstr " busta"

msgid "Next"
msgstr ""


Great would be to ignore the '&' and the '\tctrl' characters, so a
translation is easier to find, and append then again in the output
file.
Also I think for multiline string, there is a special procedure
necessary.

Or do you have better suggestions?
Many thanks in advance for your answer!
