Vista - script to parse specific gpo settings

Hi
I'm looking for ways to retrieve the specific group policy settings under
domain env for example the setting for PasswordComplexity. however, it must
be via commandline or vbscript so that i can output it to .csv(preferable) or
..txt format

I can run gpresult to get all the settings but that's not what i'm looking
for. Basically, I need the ability to query any specific gpo listed in the
policysettings.xls to get the setting for it.

Also, i'm using logparser to extract certain registries of the gpo but not
all settings are stored in registry.

Can you help?

tx very much in advance.
