Using Regular Expressions

This section describes regular expressions and provides information and examples
for using them in ColdFusion Studio. The rules listed in this section are for creating
regular expressions in ColdFusion Studio; the rules used by other RegExp parsers
might differ.
An excellent reference on regular expressions is Mastering Regular Expressions by
Jeffrey E.F. Friedl, published by O'Reilly & Associates, Inc.

About regular expressions

A regular expression is a pattern that defines a set of character strings. The RegExp
parser in ColdFusion Studio evaluates the indicated text and returns each matching
pattern.
Like in arithmetic expressions, you can use various operators to combine smaller
expressions; simple regular expressions can be concatenated into complex criteria.

In ColdFusion Studio, you can use regular expressions for extended searches and
validating code. Following is a description of each usage:
Extended search Search a document for a pattern rather than a specific string
of characters. For example, search for repeated words with
In an extended search, all matches are added to the list of results. But in an
extended search and replace, matches are immediately replaced with the
replacement text. So consider not only what is matched but what is not matched;
for example, there might be two or more strings that you must replace with the
same text. Also, it is always a good idea to back up your files first!
In a search and replace operation, the RegExp engine processes the entire
document; it does not parse on a line-by-line basis. This affects the way that you
should use characters such the asterisk (*), carat (^) and dollar sign ($).
Code validation Define a special requirement for your code in the validator.
For example, set the validator to search for (and flag as an error) any user input
box that does not have an associated error message.
