I don't know regular expression at all. Can anybody help me with one very simple regular expression which is,
extracting 'word:word' from a sentence. e.g "Java Tutorial Format:Pdf With Location:Tokyo Javascript"?
things are becoming complex with sec.....i have to learn reg ex :(
thanks in advance.

You can use the regex:
\w+:\w+
Explanation:\w - single char which is either a letter(uppercase or lowercase), digit or a _.\w+ - one or more of above char..basically a word
so \w+:\w+
would match a pair of words separated by a colon.

Try \b(\S+?):(\S+?)\b. Group 1 will capture "Format" and group 2, "Pdf".
A working example:
<html>
<head>
<script type="text/javascript">
function test() {
var re = /\b(\S+?):(\S+?)\b/g; // without 'g' matches only the first
var text = "Java Tutorial Format:Pdf With Location:Tokyo Javascript";
var match = null;
while ( (match = re.exec(text)) != null) {
alert(match[1] + " -- " + match[2]);
}
}
</script>
</head>
<body onload="test();">
</body>
</html>
