AJAX responseText

The response text that I have coming back is a complete HTML page.
Is there any way to set that response text to a document... and get the innerHTML of an element by ID???

So right now I have on my callback javascript

document.getElementById("ajax-div").innerHTML = http_request.responseText;

I would like it to be something like...

document.getElementById("ajax-div").innerHTML = http_request.responseText.getElementById("html-for-ajax").innerHTML;

responseText is a string object, and unfortunately I do not believe it is possible to do as you propose.
responseXML returs an xml stream object, which has methods similar to what you want, but the response has to be in XML format.  I've never tried using it on something that is in HTML format.  You may want to try it just to see what will happen.

Your alternative would be to change the return of the ajax request to only return the html you want, or to parse the entire html to retrieve the data you want.
Something like this:
text = responseText.value.match(/<div id=\"yourelementid\">(.*?)<\/div>/);
document.getElementById("ajax-div").innerHTML = text[0];
MorcalavinCommented:
document.getElementById("ajax-div").innerHTML = text[0];
This should be:
document.getElementById("ajax-div").innerHTML = text[1];

>>responseText.value.match(/<div id=\"yourelementid\">(.*?)<\/div>/);

Would that work if I have other div's inside this div??

I tried this method in my ASP.Net Application, but I don't know of a good way to parse it.  Do you?

responseText.value.match(/<div id=\"yourelementid\">(.*?)<\/div>/);
This will match every thing between the div tags, including other divs:

<div id=yourlementid>This is my innerHTML<div>So is this</div></div>
The above would return
"This is my innerHTML<div>So is this"

If you want to retrieve simple text, have the asp page return simple text only.  That way, no parsing is involved.  If I want to retrive the number of miles form here to there, my page should simply return the miles and nothing else.
