It would be excellent to be able to embed nmap in a network monitoring
tool ... a C program, etc .. without having to read from a pipe .. and
for glue modules it would be very nice to call a library function and
get back a list of hosts as C structs that contains a list of C structs
for ports etc .. or C++ object instances. I am curious about why you
prefer the XML route?
As far as reading from a pipe goes, reading XML is definitely much easier
than any other textual input as it has well-defined structure and there
are many APIs for reading/parsing it .. and maintenance-wise it is easier
for both parties as long as the DTD stays stable.

Sorry about that .. that was the first source-level patch I have ever done.

Sounds good ... I apologize for not reading the code a bit more and
making it consistent with the rest of the XML messages/DTD.

Will do .. once the XML backend is in place, my module set will be much
more usable .. about 800 people downloaded version .02 but I suspect few
had much luck due to the fragility of my LOG_STDOUT parsing code.
