Install this regex tester plugin into eclipse, and you'd have whale of a time testing regex <a href="http://brosinski.com/regex/" rel="nofollow noreferrer">http://brosinski.com/regex/</a>. Points to note: In the plugin, use only one backslash for character escape. But when you transcribe the regex into a Java/C# string you would have to double them as you would be performing two escapes, first escaping the backslash from Java/C# string mechanism, and then second for the actual regex character escape mechanism. Surround the sections of the regex whose text you wish to capture with round brackets/ellipses. Then, you could use the group functions in Java or C# regex to find out the values of those sections. ([_A-Za-z0-9-]+)(\.[_A-Za-z0-9-]+)@([A-Za-z0-9]+)(\.[A-Za-z0-9]+) For example, using the above regex, the following string <pre><code>abc.efg@asdf.cde </code></pre> yields <pre><code>start=0, end=16 Group(0) = abc.efg@asdf.cde Group(1) = abc Group(2) = .efg Group(3) = asdf Group(4) = .cde </code></pre> Group 0 is always the capture of whole string matched. If you do not enclose any section with ellipses, you would only be able to detect a match but not be able to capture the text. It might be less confusing to create a few regex than one long catch-all regex, since you could programmatically test one by one, and then decide which regexes should be consolidated. Especially when you find a new email pattern that you had never considered before.

1. CO@h2g2java Talking about myself, I already use a similar plugin. And I appreciate your answer very much, cuz I also find that without such tools working with regular expressions can be a nightmare. I'm sure your answer will help many people to save their time.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
