Cut <br/>-Tags from String end

I am currently developing a Web-Application using Java EE where I'm using a Rich-Javascript-Editor (http://www.primefaces.org/showcase/ui/editor.jsf). As the user can easily add too many linebreaks that will be convertet to linebreak-tags, I need to remove all these Tags from the end of a String.

Is there an elegant way of using Regex to accomplish this?

An example String would be:

"This is a test <b>bold</b><br/><br/>"

Where obviously the last two tags have to be removed.

Thank you in advance for any help

Best Regards, Robert

This should do the trick for most cases.

This regex considers most of scenarios where different forms for <br> occurs

All of the following are valid <br> statements :

-<br>
-<br/>
-<br />
-<br / >
-<br/ >
-<br //// >

This regex identifies all such forms of <br>

string = string.replaceAll("<br[\\s/]*>", "");

Something like this:

String s = "This is a test <b>bold</b><br/><br/>";
String s2 = s.replaceAll("(\\s*<[Bb][Rr]\\s*/?>)+\\s*$", "");
// s2 = "This is a test <b>bold</b>";

Note that it will also remove trailing whitespace; you can delete the final \\s* if you don't want that.

Here is a simple line of Java code to remove all instances of the substring "<br/>" from the end of a string myString:

myString = myString.replaceAll("(<br/>)+$", "");
