## Regular Expressions

Regex is a powerful pattern matching syntax that is commonly used to find text that has a certain pattern. eg 'Find all words that begin with 'W' followed by 2 numbers and ends in a vowel.

Use [regexr](http://regexr.com) to build a regex query and try it out using [Overpass](http://wiki.openstreetmap.org/wiki/Overpass_API/Overpass_QL#Value_matches_regular_expression_.28.7E.2C_.21.7E.29)



Examples:
