I don't know how the regexp version would work, but here's the code I
currently use to extract the <script> contents from the loaded content when
using my applet based loading. As it shows below, the "body" variable
contains the complete contents of the code between the <body> tags.
var bodyRE=/<body.*>\n?([\s\S]*)<\/body>/i;
var body=(bodyRE.test(src)) ? bodyRE.exec(src)[1].replace(/\r/,'') : '';
if (src.indexOf("<script")!=-1) {
var scripts=src.substring(src.indexOf("<script")).split("<script");
var length=scripts.length;
if (length>0) {
for (var i=0; i<length; i++)
scripts[i]=scripts[i].substring(scripts[i].indexOf(">")+1,scripts[i].indexOf("</script>"));
if (js!=false) for (var i=0; i<length; i++) eval(scripts[i]);
var body=body.split("/script>");
var length=body.length;
for (var i=0; i<length; i++)
body[i]=body[i].substring(body[i].indexOf("/script>")+1,body[i].indexOf("<script"));
body=body.join("");
};
};
It should be possible to use the same looping method used in the newer
dragdrop code.
I could't seem to get a regexp version that allowed fr the returning of an
array of results. If anyone out there knows of a method that works, I'd be
pleased to see it in action.
