How to navigate result XML

Modified By Stefan Kamphuis on 2/4/2006 6:18:31 PM)

Hi,

Knowing I'm not exactly a javascript guru, I started playing around with Jon's HelloAjax sample module. The sample return a single string value and alerts it. I changed this to return a simple XML document:
<HelloAjax>
    <Message>blabla</Message>
    <DateTime>2/5/2006 12:02:53 AM</DateTime>
</HelloAjax>

In the clientside script I want to navigate through this xml document and (for example) give an alert with the contents of the <Message> element. I have the following code now, which results in an alert saying "<Message>blabla</Message>" (so this includes the element tags):

function successFunc(result, ctx)
{
    var dom = new dnn.xml.createDocument();
    dom.loadXml(result);

    var topNode = dom.childNodes(0);
    var msgNode = topNode.childNodes(0);

    alert('Message: ' + msgNode.getXml());
}

Any ideas on how I should navigate through the XML to get to an element and get it's contents?

Thanks.

Re: How to navigate result XML

Looks like you are on the right path for keeping it cross-browser compatible by using the clientapi for your xml parsing. I think what you are looking for is the findNode method.

See the ClientAPI documentation for a list of methods available. (Click on the xml link in the tree on the left).

Cross-browser compatibility is exactly the reason to use the ClientAPI. I looked into my local clientapitests folder, but that contained only a few methods. Thanks for the link (and the great job on the API).
