What every web developer should know about regular expressions

There is an absolute bare minimum every programmer should know about regular expressions, says Mike.

I can’t agree more. Regular expressions are incredibly useful and a bit scary on first. Head on over to the linked article above to get information on:

• The Line Anchors: ‘^’ and ‘$’
• The Character Class: ‘[]‘
• The Character Class Metacharacter: ‘-’
• Matching Any Character With a Dot: ‘.’
• The Alternation Metacharacter: ‘|’
• Matching Optional Items: ‘?’
• The Other Quantifiers: ‘+’ and ‘*’
• The Interval Quantifier: ‘{}’
• The Escape Character: ‘’
• Using Parenthesis for Matching: ‘()’

Really great stuff.
