How to add my own start method to existing HTML::Parser class to Scrape Screens?

I'm trying to screen scape some information off the web. I anticipate that I'll want to have it multi-threaded. As per Lincoln Stein's book, I'm using HTML::Parser and passing a function pointer (you can tell I'm a C programmer) to $parser->handler(start=> \&start, 'self,tagname, attr,text,skipp

Starting Template for calling C from Perl

I was looking at "Programming Perl" trying to understand how to write OS vendor neutral C functions to be called by perl and felt a little overwhelmed (as usual when reading that book). Can someone recommend a template that works with windows/MSVC/nmake or Cygwin/GCC/make (unix clone for windows p

Re: Starting Template for calling C from Perl

I don't think there are any such examples besides the manual. There are generally clear warnings as to why not to try to do the c code from scratch. Either work with the xs system directly, or try http://www.swig.org which has good and bad sides to it. If you described the problem you're having I c

Comparing results of type unknown

Hi List, I want to compare the two rows of db result returned by query using DBI module. If I simply use != operator it gives me error when comparing the columns which are of char type.
