Get content within a tag using Javascript from HTML

I want a javascript code which will go through all the html file in my root folder and sub-folders and gets the content which are within a particular tag, eg: 

<div id="content">
!!this content!!
</div>

It should check for a comment at the top of html and only get the content if it exist.

<!--Allowed-->

It should only get if this is there. First of all is this possible? I wish jquery could do this!

Update: Got enlightened that javascript is for client-side! So One last question, how does you use php to get the content that is within the a particular tag?

    <div id="content">
    !!this content!!
    </div>

If you know the exact content of the comment you're searching for, try this:

if(document.documentElement.innerHTML.indexOf('<!--Comment-->') > 0){
    //voila!
}

If not, you can use regular expressions to parse the text. I'm not an expert in regex, so i can't say i can help you there.
Of course, this will only work on a per-page basis, it won't browse your file system. For that you should have a server-side language.
Hope this helps

No it is not possible with javascript. It is a client side scripting language. You need a serverside scripting language like PHP. Check out http://php.net/ look up the fopen(), include(), and dir() functions.

Javascript has no access to the file system. You need a server side language to do that.

At first you have to get all the folders that are in the folder (on the server). That's not possible with JavaScript alone. You have to write a PHP (or any other web-language supported on your webspace/server) which gives you the filename-list. Then you can load each file with jQuery's ajax-functions and test for your comment, etc.
