Attempting to utilize regular expressions to substitute HTML tags

I am working on a task to substitute

<script type='text/javascript'>some stuff</script>

with:

<div type='text/javascript'>some stuff</div>

My current testing method involves:

alert( o.replace( /(?:<\s*\/?\s*)(script)(?:\s*([^>]*)?\s*>)/gi ,'div') );

However, the result I'm getting is:

divsomestuffdiv

Is there a way to only replace the "script" part while maintaining the other HTML tags and attributes?

Answer №1

Ensure to keep the starting and ending tag brackets intact. Give this a shot:

r.replace(/(<\s*\/?\s*)style(\s*([^>]*)?\s*>)/gi ,'$1span$2')

Answer №2

One possible approach is to handle this task in two separate passes. The first pass would involve identifying and replacing the following code snippet:

<script

with an equivalent snippet:

<div

The second pass would then focus on matching the closing tag:

</script>

and substituting it with:

</div>

Answer №3

Utilizing DOM methods is a more effective approach compared to using regular expressions when it comes to manipulating your document. By doing so, you are able to handle the content logically instead of treating it as plain text:

var elements = document.getElementsByTagName('script');
for (var index = 0, element; element = elements[index]; index++) {
    var newElement = document.createElement('div');
    newElement.type = element.type;
    element.parentNode.replaceChild(element, newElement);
}
