Find and Display Values in textbox help!

I currently have a textfile in the following format:

"[Contestants]Chris=12345Cody=54321Dylan=32451Michelle=98765"

How do I pull the first name out and have it appear in textbox1 showing just the Value Chris has Chosen? The textbox should read, "12345"!

I have searched the internet but have failed to find one that works for me!
