ajax-externalhtml-div issues

Hi, im trying to do some experimental ajax/javascript/dhtml work
based on a dynamic drive tutorial.

http://www.dynamicdrive.com/dynamici...tent.htm#combo

my problem is that i cannot find ANY information ANYWHERE AT ALL
on how to select a <div> from the EXTERNAL html page beingloaded.

basically i dont want to load an entire page. i only want to load specified
<div>s into other div containers.

can anyone help me?

I have narrowed it down to the following pieces of code:

function loadpage(page_request, containerid, originid){
if (page_request.readyState == 4 && (page_request.status==200 || window.location.href.indexOf("http")==-1))
document.getElementById(containerid).innerHTML=pag e_request.responseText
}

the LAST line document.getElementById(containerid) works and publishes
the entire html page (external.htm) into containerid in the index.htm page

BUT whenever i try to add ANY code to:

innerHTML=page_request.responseText
such as
innerHTML=page_request.getElementById(originid).re sponseText
or
innerHTML=page_request.responseText.getElementById (originid)
or
innerHTML.getElementById(originid)=page_request.re sponseText

NOTHING WORKS!!!

i'd be super appreciateive of anyone who might be able to guide me as to how to format my syntax so this can be done.

I know my originid and containerid variables are passing b/c i alerted them and they DEFINITELY work. it just has to do with the fact that i cant find any documentation on the proper way to do this (internet and like 4 books today scoured!)

thanks in advance to anyone out there

That's the incorrect syntax. What you probably want to do is parse responseText for the information that you want and then set the innerHTML to the parsed data.

Show an example of data/div that you want from a page.

that's the problem. im such a newbie im not even sure how to start going about this.

can you possibly point me in the correct direction
as in how to start parsing that data properly in ajax/js?

im mostly a flash programmer and thisi s my first hardcore ajax/js dealyo.

thanks also for helping me at least know what i need to look into for a solution.
