This gets very difficult since the expression no longer remains regular (technically it becomes a context grammar). I would simply write it in Javascript.

I am using Angular-JS and have the following expression, which checks a password input for 1 upper case letter, 1 lower case letter, 1 number, and one special character. &nbsp;However, I need it to check for 2 or more upper case letters, 2 or more lower case letters, 2 or more numbers, and 2 or more special characters. &nbsp;How do I modify the below expression to check for two or more instead of one or more?<br />

Search for 2 or more items in password validation using regular expression.

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.

Regular Expressions

Angular is a JavaScript open-source web application framework used to develop single-page applications. It aims to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–view-model (MVVM) architectures, along with components commonly used in rich Internet applications. Angular is the front-end part of the MEAN stack, together with Node.js runtime, Express.js backend framework and MongoDB database.
