If you use VBScript to validate user input on a web page at the client side, using VBScript’s built-in regular expression support will greatly reduce the amount of code you need to write. RegexBuddy makes it very easy to use the RegExp object in your VBScript source code and web pages.
The VBScript RegExp Object uses the exact same regular expression flavor as JavaScript as implemented by Internet Explorer 5.5 and by later versions of Internet Explorer when running in Quirks mode. This implementation is not fully compliant with the ECMAScript standard and thus not fully compatible with modern browsers. Fortunately, RegexBuddy is aware of all the differences. You can compare your regex and RegexBuddy will tell you if it may behave differently with VBScript that with JavaScript in modern browsers.
First, use RegexBuddy to define a regex or retrieve a regexp saved in a RegexBuddy library. Rely on RegexBuddy’s clear regex analysis, which is constantly updated as you build the pattern, rather than dealing with the cryptic regex syntax on your own. Detailed help on that syntax is always only a click away.
If you copied a regex written for another programming language, simply paste it into RegexBuddy, select the original language, and then convert the regex to VBscript.
If you created a new regular expression, test and debug it in RegexBuddy before using it in your VBScript source code. Test each regex in RegexBuddy’s safe sandbox without risking precious data. Quickly apply the regex to a wide variety of input and sample data, without having to produce that input through your script.
Finally, let RegexBuddy generate a source code snippet that you can copy and paste directly into whichever IDE or code editor you use. Just choose what you want to use the regex for, and a fully functional code snippet is ready. You can change the names of variables and parameters to suit your naming style or the current situation, which RegexBuddy automatically remembers.
Don’t bother trying to remember VBScript’s specific regexp syntax. Just tell RegexBuddy what you want to do, and you will get the proper VBScript code straight away. Anything can be done: testing a string for a match, extracting search matches, validating input, search-and-replace, splitting a string, etc.
