What is the Regular Expression Action?

The Regular Expression Action runs a regular expression on a value. This is an advanced Action designed for programmers familiar with using regular expressions.

Note: A regular expression is a sequence of characters that define a search pattern.  There are many online resources available that explain how to write a regular expression including:

Specify the Value to be parsed with a regular expression.

Enter the Expression to be used to parse the value.

Select the method:

• Match

• If Match is selected, you must select your sub method:
• All matches
• First match
• Last match
• Match Count
• Exact Count

If Replace is selected, specify what to replace all matches with.

Select whether to save the output to:
