I should have mention this is for integration in an open source/ cross
platform toolkit with BSD license. For now I use tricks to link to
private header of -system installed- poppler (due to API changes). But
I still lack a PDF parser for Win32 platforms.

If I find some time, I might get started with this python parser I
found on the net:

It is self contained, and is exactly focus on what I am looking for a
stream interface (what is SAX to XML people) for PDF people.

Thanks anyway,
