Finding fields in String java regular expression

I am not good at Java regular expressions.

I have following text

[[image:testimage.png||height=\"481\" width=\"816\"]]

I want to extract image: , height and width from above text. Could someone help me writing regular expression to achieve it ?

Try this regex:

((?:image|height|width)\D+?([a-zA-Z\d\.\\"]+))

You will get two groups.

e.g.,

1. height=\"481\"
2. 481
