This is a test form for regular expression match and replace.
This builds on the information in the previous version.
You can enter patterns, replacement strings and subject strings in the text entry boxes, and click the "Test!" button to run the match, and perform the replacement, if the pattern matches in the subject text. The additional buttons at the bottom of the form will fill some sample text values into the form. The samples show a few uses of the regular expression meta-characters, quantifiers and character classes described in the text. Feel free to modify the text in the pattern or subject string and re-test the expression.
