Regular expressions are patterns that describe character combinations in text. Dreamweaver support for regular expressions empowers web developers by enabling them to find and quickly replace content with surgical-like precision.
In some cases, a web developer may want to create a regular expression that updates content such as changing copyright information throughout a site. Another example might be the case where a web developer wants to search quickly for declarations of a variable.
In this article, I will provide a basic overview of regular expressions as well as an example of how they can be used to help maintain Cascading Style Sheet (CSS) code on your site.
To further understand the intricacies of this pattern-matching language, I encourage you to refer to additional resources on regular expressions that explore the subject in greater detail.
