I will give u feedback soon.

}

var func=new Function(“match”,”var link=document.createElement(\”A\”); link.textContent=match; link.setAttribute(\”href\”,\”"+url+”\”); return link;}”);

function replaceTextContent(regexp,handler) {
var snapshots=document.evaluate(“//body//text()”,document,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for(var num1=0;num1<snapshots.snapshotLength;num1++) {
regexp.lastIndex=0;
var node1=snapshots.snapshotItem(num1);
if (isALink(node1)) continue;
var match1=regexp.exec(node1.textContent);
if (match1) {

var node2=node1.parentNode;
var node3=node1.nextSibling;
node2.removeChild(node1);
while (match1) {
if(isALink(node2)) {

node2.insertBefore(document.createTextNode(RegExp.leftContext),node3);
try{node2.insertBefore(handler(match1),node3);}
catch(ex){node2.insertBefore(document.createTextNode(match1),node3);}
regexp.lastIndex=0;
match1=regexp.exec(RegExp.rightContext);
}
}
node2.insertBefore(document.createTextNode(RegExp.rightContext),node3);
}
}
}

Do you think you can help me, either by modifying this to work or scratching and starting fresh. Thanks

Yes it can be done easily and not too hard. The idea may be link this. After the whole page is loaded I mean the dom,
1. Get the whole html.
2. Search with regex for specific word (here content in your word)
3.Replace the matched text with specific word.

The task is simple but need some time to do
