IE:

<body onload='mybody. innerText=mybod y.innerText.rep lace(/foo/g,"bar")'>
<div id="mybody">
blah foo<br>
blah foo
</div>
</body>

<div id="mybody">
blah foo<br>
blah foo
</div>
</body>

I don't have a <div> to grab "mybody" as a handle. I have to simply make
the change to whatever text is within <body>.

1/ It is not innertext, but innerText

2/ Why do you let yourself be constricted that way ? It seems you want to
change somone elses work. This could be unetical. The final p[ossibilitiy
is called "html-mining".

Best guess is to run through the DOM tree:
---
function crawlDOM(node,f node,ftext) {
switch (node.nodeType) {
case 1: // normal node
for(var i = 0;i<node.childN odes.length; i++) {
crawlDOM(node.c hildNodes[i],fnode,ftext);
}
fnode(node);
break;
case 3: // text node
ftext(node);
break;
}
}
---

Then you can do:
---
crawlDOM(docume nt.body,
function (){},
function (tnode) {
tnode.nodeValue = tnode.nodeValue .replace(/foo/g,"bar");
});
---

You just have to pray that the document tree really is a tree :)

Change text color on a submit button when clicked?
