What is your real problem? Do you want to remove whitespace before inserting nodes in the document?

I want to remove all leading white spaces as well as all trailing white spaces. Very my like the Trim method in C# except that it removes even white spaces.

See the String method trim() - https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/String/Trim
var myString = ' bunch of <br> string data with<p>trailing</p> and leading space ';
myString = myString.trim();
// or myString = String.trim(myString);
Edit
As noted in other comments, it is possible to use the regex approach. The trim method is effectively just an alias for a regex:
if(!String.prototype.trim) {
String.prototype.trim = function () {
return this.replace(/^s+|s+$/g,'');
};
}
... this will inject the method into the native prototype for those browsers who are still swimming in the shallow end of the pool.

Read the question, is used instead of an ordinary whitespace. On top of this, the whitespace is contained within a tag.

If you're working with a multiline string, like a code file:
<html>
<title>test</title>
<body>
<h1>test</h1>
</body>
</html>
And want to replace all leading lines, to get this result:
<html>
<title>test</title>
<body>
<h1>test</h1>
</body>
</html>
You must add the multiline flag to your regex, ^ and $ match line by line:
string.replace(/^s+|s+$/gm, '');
Relevant quote from docs:
The "m" flag indicates that a multiline input string should be treated as multiple lines. For example, if "m" is used, "^" and "$" change from matching at only the start or end of the entire string to the start or end of any line within the string.

I know this is a very old question but it still doesn't have an accepted answer. I see that you want the following removed: html tags that are "empty" and white spaces based on an html string.
I have come up with a solution based on your comment for the output you are looking for:
Trimming using JavaScript<br /><br /><br /><br />all leading and trailing white spaces
var str = "<p> </p><div> </div>Trimming using JavaScript<br /><br /><br /><br />all leading and trailing white spaces<p> </p><div> </div>";
console.log(str.trim().replace(/ /g, '').replace(/<[^/>][^>]*></[^>]+>/g, ""));.trim() removes leading and trailing whitespace
.replace(/ /g, '') removes
.replace(/<[^/>][^>]*></[^>]+>/g, "")); removes empty tags

Will it remove white spaces like <br /> or <p> </p> <div> </div> ? Trmming simple spaces is not a problem. Its the white space removal that I am after.

01). If you need to remove only leading and trailing white space use this:
var address = " No.255 Colombo "
address.replace(/^[ ]+|[ ]+$/g,'');
this will return string "No.255 Colombo"
02). If you need to remove all the white space use this:
var address = " No.255 Colombo "
address.replace(/s/g,"");
this will return string "No.255Colombo"

@Flimzy: Yes, it would make more sense to write
[tn ] or just s instead of [ ] which makes no sense.– erik

Read the question, is used instead of an ordinary whitespace. On top of this, the whitespace is contained within a tag.

If you're working with a multiline string, like a code file:
<html>
<title>test</title>
<body>
<h1>test</h1>
</body>
</html>
And want to replace all leading lines, to get this result:
<html>
<title>test</title>
<body>
<h1>test</h1>
</body>
</html>
You must add the multiline flag to your regex, ^ and $ match line by line:
string.replace(/^s+|s+$/gm, '');
Relevant quote from docs:
The "m" flag indicates that a multiline input string should be treated as multiple lines. For example, if "m" is used, "^" and "$" change from matching at only the start or end of the entire string to the start or end of any line within the string.

I know this is a very old question but it still doesn't have an accepted answer. I see that you want the following removed: html tags that are "empty" and white spaces based on an html string.
I have come up with a solution based on your comment for the output you are looking for:
Trimming using JavaScript<br /><br /><br /><br />all leading and trailing white spaces
var str = "<p> </p><div> </div>Trimming using JavaScript<br /><br /><br /><br />all leading and trailing white spaces<p> </p><div> </div>";
console.log(str.trim().replace(/ /g, '').replace(/<[^/>][^>]*></[^>]+>/g, ""));.trim() removes leading and trailing whitespace
.replace(/ /g, '') removes
.replace(/<[^/>][^>]*></[^>]+>/g, "")); removes empty tags

Will it remove white spaces like <br /> or <p> </p> <div> </div> ? Trmming simple spaces is not a problem. Its the white space removal that I am after.

01). If you need to remove only leading and trailing white space use this:
var address = " No.255 Colombo "
address.replace(/^[ ]+|[ ]+$/g,'');
this will return string "No.255 Colombo"
02). If you need to remove all the white space use this:
var address = " No.255 Colombo "
address.replace(/s/g,"");
this will return string "No.255Colombo"

I want to remove all leading white spaces as well as all trailing white spaces. Very my like the Trim method in C# except that it removes even white spaces.
