Lazyanno,

If and only if:

1. you have read SLaks's post (as well as the previous article he links to), and


2. you fully understand the numerous and wondrous ways in which extracting information from HTML using regular expressions can break, and


3. you are confident that none of the concerns apply in your case (e.g. you can guarantee that your input will never contain nested, mismatched etc. <b>/</b> tags or occurrences of <b> or </b> within <script>...</script> or comment <!-- .. --> tags, etc.)


4. you absolutely and positively want to proceed with regular expression extraction

...then use:

var str = aa<b>1;2'3</b>hh<b>aaa</b>..n.<b>bbb</b>nblabla..;



var match, result = , regex = /<b>(.*?)</b>/ig;

while (match = regex.exec(str)) { result += match[1]; }



alert(result);

Produces:

1;2'3aaabbb
