I just stumbled upon rexv.org, which looks like the swiss army knife of online reg ex tools. It is somewhat limited to PHP (PCRE and Posix) and Javascript RX implementations, but still these tend to be among most popular. You can set all the bits and pieces yourself using checkboxes to modify the nature of constructed rx – the options include greediness, case-sensitivity, new lines and unicode.I always wanted to straigth out test the regular expression I envisioned on my copy of content, e.g. to see if I can extract links from HTML page and so on. And guess what – rexv.org can do just that, showing you matches. It can also work in replacement mode where you instantly see what your string would turn into under the influence of currently provided rx. Great!!!
