Regular expression

If I have a String like below:|ClientId=12345|GUID=klsLDFjlSf09SDf9|KeygenLoc=APPLIANCE|

How can I parse out the Client ID (i.e. the "12345" on its own) value via a regular expression?

Many thanks!

Do you need a regex?
Try myString.substring(myString.indexOf("ClientID=") + "ClientID=".length(), myString.indexOf("|GUID"));

Try getting the () paired off correctly!

What have you tried so far? It is pretty straightforward -- can be done with a single method call.
