sed and regular expressions problem

Hi

Im trying to use sed to change some files which I'll describe here:

I want to use a regular expression to grab the <body> tag from a document. However, the <body> tag can look different so the regular expression used will take care of that and "include" all types of bodies, in example: <body background="green" > will also be replaced. However, that text that goes directly after body, in this case ' background="green" ' needs to be included in the output.

"s/<body[^>]*>/<body(I want the trimmed content here)>CONTENT/g"

So basically the question is how (and if its possible) to add that content to the output line?
<body background="green" > should become <body background="green" >CONTENT
and
<body> should become <body>CONTENT

If you don't understand what I mean, just ask me and I'll try to describe it in another way

Thank you!
