Hi, I am looking for a solution to use ajax.request object. Return response text will be in xml format and I like to know how to parse that xml information, so that I can put those info into the "span" or "div" tags of my html page. Is there any easy way to parse that xml info using prototype library? Thanks, kevin. -- Posted via http://www.ruby-forum.com/.
Hi Kevin,
I lifted the following code:
onSaveComplete: function(response)
{
var ajaxResponse = Try.these(
function() { return new DOMParser().parseFromString(response.responseText,
''text/xml''); },
function() { var xmldom = new
ActiveXObject(''Microsoft.XMLDOM'');
xmldom.loadXML(response.responseText); return xmldom; }
);
var personid
ajaxResponse.getElementsByTagName(''personid'')[0].firstChild.nodeValue;
}

Hope this helps!

Subject: [Rails] prototype ajax + xml response
Hi,
I am looking for a solution to use ajax.request object.
Return response text will be in xml format and I like to know how to
parse that xml information, so that I can put those info into the
"span"
or "div" tags of my html page. Is there any easy way to parse that
xml
info using prototype library?
Thanks,
kevin.

Er, what''s wrong with response.responseXML? A parsed XML tree is
already
available from the XMLHttpRequest object.
} Hope this helps!

I read somewhere that this can happen if the mime type isn''t set to "text/xml", and I''ve concluded that prototype doesn''t have a way of setting this. I''d love to be able to rely on .responseXML - do you know how to ensure it will be set? Tony S. -- Posted via http://www.ruby-forum.com/.

Well, the MIME type needs to be set properly. I haven''t touched the prototype library, but my understanding is that it is solely on the JavaScript side, not the Ruby side. In your Rails action you need to set the MIME type. If I am wrong and prototype is on the Rails side as well., modify it. You have the source, after all. Make sure it is setting the MIME type. } Tony S. --Greg

Once I realised the problem was that the rails action wasn''t saying that it was sending XML it gave me a place to start looking. After a while I figured out how to set the response header. It''s all about how you look at it ... Tony S. -- Posted via http://www.ruby-forum.com/.
