Sed question?

I have what should be a simple problem. I can grep out a line from a file that looks like...

<password information="wiuihm@kj*"/>

I want to capture the data between the ". The problem is that the data can be surrounded with single or double quotes.

I think I can get it working with "cut", but not with variable delimiters.

Any ideas? Maybe sed?

sed is more for replacement really, but here's the regexp you'd be looking for

/("|').+("|')/
