i've an well formed html document like this:
<html>
<head>
..
</head>
<body>
..
</body>
</html>
i want to positionally place this <body>..</body> content programatically? is this possible? basically my problem is i've to insert a javascript function before </head> and put that navigation after <body> tag and move all the content to after navigation using a DIV tag and i've to close the div tag before </body.
is this can be done without parsing the whole html? because sometimes my html sizes are too big and that means my server would run out of memory every nown then. any suggestions?

With javascript you can do more or less anything inside the body tag, either e.g. by string-manipulating the body's innerHTML or with pure DOM manipulation - by creating and inserting elements where you want them. Or even combining the 2 methods.
For instance you cauld create a div, assign it the body's innerHTML and then append the div to the body.
There are different ways to do it and different opinions about the best way to go.
Here's a very simple example. If you comment out
window.onload=wrapItUp;
you'll see the difference:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html
<html>
<head>
<style>
#wrapper { background-color: #ddd; height:400px; }
#nav { background-color: #00f; width:400px; height:20px; margin-top:40px;}
</style>
<script>
function wrapItUp() {
var wrap=document.createElemen
wrap.id='wrapper';
var nav=document.createElement
nav.id='nav';
nav.innerHTML=' ';
wrap.innerHTML=document.bo
document.body.innerHTML=''
document.body.appendChild(
document.body.appendChild(
}
window.onload=wrapItUp;
</script>
</head>
<body>
<textarea id="txt">
</textarea>
<table border="1">
<tr>
<td>aaa</td>
<td>bbb</td>
<td>ccc</td>
<td>ddd</td>
</tr>
</table>
<form name="frm1">
<input type="text">
<input type="button">
</form>
<div id="div1">Test</div>
</body></html>
Try this:
Your html file:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html
<head>
<script type="text/javascript">
window.onload=function() {
var sc = document.createElement("sc
sc.setAttribute("type", "text/javascript");
sc.setAttribute("src", 'script.js');
document.getElementsByTagN
}
</script>
</head>
<body>
</body>
</html>
And "script.js" could contain for instance:
alert('Inserted script!');

When you say you want to do this programmatically, what programming language are you using to generate the html code?
