sed and regular expressions problem

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!

Mail::SpamAssassin::Plugin::ReplaceTags(3pm) User Contributed Perl Documentation Mail::SpamAssassin::Plugin::ReplaceTags(3pm) NAME
Mail::SpamAssassin::Plugin::ReplaceTags - tags for SpamAssassin rules The plugin allows rules to contain regular expression tags to be used in regular expression rules. The tags make it much easier to maintain complicated rules. Warning: This plugin relies on data structures specific to this version of SpamAssasin; it is not guaranteed to work with other versions of SpamAssassin. SYNOPSIS
loadplugin Mail::SpamAssassin::Plugin::ReplaceTags replace_start < replace_end > replace_tag A [a@] replace_tag G [gk] replace_tag I [il|!1y?xccxcdxcexcfxecxedxeexef] replace_tag R [r3] replace_tag V (?:[vu]|\/) replace_tag SP [s~_-] body VIAGRA_OBFU /(?!viagra)<V>+<SP>*<I>+<SP>*<A>+<SP>*<G>+<SP>*<R>+<SP>*<A>+/i describe VIAGRA_OBFU Attempt to obfuscate "viagra" replace_rules VIAGRA_OBFU RULE DEFINITIONS AND PRIVILEGED SETTINGS
replace_tag tagname expression Assign a valid regular expression to tagname. Note: It is not recommended to put quantifiers inside the tag, it's better to put them inside the rule itself for greater flexibility. replace_pre tagname expression Assign a valid regular expression to tagname. The expression will be placed before each tag that is replaced. replace_inter tagname expression Assign a valid regular expression to tagname. The expression will be placed between each two immediately adjacent tags that are replaced. replace_post tagname expression Assign a valid regular expression to tagname. The expression will be placed after each tag that is replaced. replace_rules list_of_tests Specify a list of symbolic test names (separated by whitespace) of tests which should be modified using replacement tags. Only simple regular expression body, header, uri, full, rawbody tests are supported. replace_start string replace_end string String(s) which indicate the start and end of a tag inside a rule. Only tags enclosed by the start and end strings are found and replaced. perl v5.14.2 2011-06-06 Mail::SpamAssassin::Plugin::ReplaceTags(3pm)
