RegexBuddy is your companion for working with regular
expressions. Easily create regular expressions that match
exactly what you want. Clearly understand complex regexes
written by others. Use plain English building blocks
instead of or in addition to the standard regex syntax.
Quickly test any regular expression on sample strings and
files, preventing mistakes on actual data. Debug without
guesswork by stepping through the actual matching process.
Use the regex in your source code with code snippets
automatically adjusted to the particulars of C#, Visual
Basic, Java, C, C++, Delphi, Perl, PHP, Python,
JavaScript, VBScript, REALbasic, Ruby and XML.
