I have this web application which needs to do several heavy text processing tasks: removing certain characters, parsing XML files, among others. Some of them involve regular expressions.
The web application has some implementations in Java and others in PHP. Is it worth using Perl or other specific text processing language for such tasks, or is there really no difference with using PHP?
I even thought of using Sed, Awk maybe even some compiled C scripts for processing texts. There's a lot of text to be processed...
