[RegExp->ReplaceFirst]

[RegExp->ReplaceFirst] is a utility tag which replaces the first instance of the find pattern in the input string with the replacement pattern and returns the result. The tag accepts optional parameters to override the -Find, -Replace, or -Input with new values.

The [RegExp->ReplaceAll] tag functions similarly, but replaces every instance of the find pattern in the input string with the replement pattern.

Usually this tag will be used to apply the same find and replacement pattern against several different inputs. Since the find and replacement patterns are only compiled once a series of search/replace operations on different strings can be performed faster than with individual [String_ReplaceRegExp] tags.
