Regular Expressions - training course
Making the most of Pattern Matching
Duration: 1 day • Price: $550.00 or £350.00 (VAT free from January 2019), • Venue: Melksham, England

Usually scheduled to meet customer needs or run as a private course. Please email for details
Regular expressions are probably the most powerful pattern matching tools that is available. In just one or two short lines of code, the knowledgable programmer can write code that would be 10 times as long using any other technique. But Regular Expressions aren't intuitive, even to otherwise experienced code writers.

This course refreshes any knowledge of Regular Expressions that you have from first principles, and shows you how to make effective use of them for recognising, capturing and altering patterns. You will learn how Regular Expression engines work, and learn how to write code that's going to run well and fast. We then go on to study some of the more advanced features such as look ahead, sparse matching, back referencing, etc.

You are encouraged to bring along samples of your data for us to look at during the day so that you'll go away with practical examples of how you'll be using regular expressions after this course!
Working knowledge of any one of Perl, PHP, Tcl, Python, Ruby or Java.

Regular Expressions provide a powerful tool for matching strings - for example, if you wanted to look at some text in your program and work out whether it was in the correct format for a postcode, you would use a regular expression. But ... regular expressions are so terse and yet flexible that they're very hard for the newcomer to self-teach, which is why we offer this one day course.
