Differences between two sets of texts
Posted on 2003-11-09
Hi, If i have 2 sets of texts (stored in an array, not that that should matter)
and i need to specify all the differences on one of them, is there a function that automatically compares an entire text returning all the positions (perhaps) where the texts begin to differ and end differing.
More specifically: I have a program that grabs html from a site, and then grabs it again a few seconds later to check whether it has changed. If the texts differ, then the more recent text has to be printed to stdout, highlighting (changing the font to red) where the more recent text is different.
If there isn't already a function, what would be a good method to go about this?
