Welcome to the forum.

First off, I never reccomend editing in-place, but you've had the wisdom to use backup files so that's good.

You don't need to escape the numbers, which is probably why it's complaining about backreferences. Don't think you need to escape <> either.

Another trick is you can put characters inside [] to 'escape' them, since sed won't treat most special characters in a range block as special. In some situations this is easier to read.

This seems to work.

Code:

$ cat data

BEFORE
<script LANGUAGE="JavaScript1.1">
<!--

function mMz()
{
 var mPz = "";
 for(var prop in this) {
 if ((prop.charAt(0) == '_' && prop.charAt(prop.length-1)=='_')
                      || ((typeof this[prop]) == 'function'))
 continue;
 if (mPz != "") mPz += '&';
 mPz += prop + ':' + escape(this[prop]);
 }
 var cookie = this.gHa + '=' + mPz;
 if (this._expiration_)
 cookie += '; expires=' + this._expiration_.toGMTString();
 if (this._path_) cookie += '; path=' + this._path_;
 if (this._domain_) cookie += '; domain=' + this._domain_;
 if (this._secure_) cookie += '; secure';

 this._document_.cookie = cookie;
}
//-->
</script>
AFTER

$ sed '/<script LANGUAGE="JavaScript1[.]1">/,/<[/]script>/d' data

DESCRIPTION

       The JPackage Project has two primary goals:

	- To provide a coherent set of Java software packages for Linux, satisfying all quality requirements of other applications.

	- To establish an efficient and robust policy for Java software packaging and installation.
	 We  focus  on	free and open source software whenever possible. For convenience, we also provide non-free packages without the restricted
	 source code.

       Our RPMs are generic in that they should work on any RPM based Linux distribution (Mandriva, Red Hat, SuSE, others). Other packaging format
	 suggestions are welcome too.
