I am trying to write a small online price comparison-agent, but I have no experience doing something similar before. My intention is to query search engines for a product and try to my own algorithm to parse the returned values for the prices and compare them.
Can any experienced developer tell me whether or not this is the right way to proceed? if not, can you tell me how to go about this (also suggest Perl modules which can be used)? I am unsure whether the libwww could be used for this. I have spent some time searching the web for an example of comparison agent codes, but found none. It looks like such algorithms are kept secret by their owners. Please give code examples if possible. Regards Mimi
