Going beyond user agents...

[switzer]

There are a couple of other string parsing libraries that I would love to see a comparison / performance test of:

1. Domain parsing - given a hostname (or URL), return the domain name (like https://github.com/Synchro/regdom-php)
2. URL parsing - given a URL string, show the different parts of the URL (like scheme, host, etc.), and evaluate on how well they extend into getting the search query, account number, user ID, or other items hidden in the path/query.

Thanks!
