How to Parse XML Response Using jQuery

Question

I am trying to parse an xml response using jQuery and just output an element the a page but i am unsuccessful in this.

Below is the code that I am using for the response & parsing of it.

$.ajax({
    url: UCMDBServiceUrl,
    type: "POST",
    dataType: "xml",
    data: soapMessage,
    success: UCMDBData,
    crossDomain: true,
    contentType: "text/xml; charset=\"utf-8\""
});
alert("Sent2");
return false;
}

function UCMDBData(xmlHttpRequest, status, msg)
{
     alert("Came back1");
     $(xmlHttpRequest.responseXML).find('tns:CIs').each(function()
     {
        alert("Came back2");
        $(this).find("ns0:CI").each(function()
        {
            alert("Came back3");
            $("#output").append($(this).find("ns0:ID").text());
        });
     });     
}

I am receiving alerts for "Came back1" but it doesnt appear to be going any further. Below is the XML Response that I am trying to parse using my above jquery code. The text that I am ultimately trying to return out of the response is in this element

<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header />
    <soapenv:Body>
        <tns:getFilteredCIsByTypeResponse xmlns:ns0="http://schemas.hp.com/ucmdb/1/types" xmlns:ns1="http://schemas.hp.com/ucmdb/ui/1/types" xmlns:ns2="http://schemas.hp.com/ucmdb/1/types/query" xmlns:ns3="http://schemas.hp.com/ucmdb/1/types/props" xmlns:ns4="http://schemas.hp.com/ucmdb/1/types/classmodel" xmlns:ns5="http://schemas.hp.com/ucmdb/1/types/impact" xmlns:ns6="http://schemas.hp.com/ucmdb/1/types/update" xmlns:ns7="http://schemas.hp.com/ucmdb/discovery/1/types" xmlns:ns8="http://schemas.hp.com/ucmdb/1/types/history" xmlns:tns="http://schemas.hp.com/ucmdb/1/params/query">
            <tns:CIs>
                <ns0:CI>
                    <ns0:ID>4d030502995a00afd989d3aeca2c990c</ns0:ID>
                    <ns0:type>nt</ns0:type>

                        <ns0:strProps>
                            <ns0:strProp>
                                <ns0:name>name</ns0:name>
                                <ns0:value>prodoo</ns0:value>
                            </ns0:strProp>
                        </ns0:strProps>
                        <ns0:booleanProps>
                            <ns0:booleanProp>
                                <ns0:name>host_iscomplete</ns0:name>
                                <ns0:value>false</ns0:value>
                            </ns0:booleanProp>
                        </ns0:booleanProps>
                    </ns0:props>
                </ns0:CI>
            </tns:CIs>
            <tns:chunkInfo>
                <ns0:numberOfChunks>0</ns0:numberOfChunks>
                <ns0:chunksKey>
                    <ns0:key1 />
                    <ns0:key2 />
                </ns0:chunksKey>
            </tns:chunkInfo>
        </tns:getFilteredCIsByTypeResponse>
    </soapenv:Body>
</soapenv:Envelope>

So my question is that how do I properly parse the data? I believe the code syntax is correct but I am not getting the expected returned results. I would appreciate any help, thanks.

EDIT

I have modified my code to the following like the suggestion, but still no luck:

$.ajax({
    url: UCMDBServiceUrl,
    type: "POST",
    dataType: "xml",
    data: soapMessage,
    success: UCMDBData,
    crossDomain: true,
    contentType: "text/xml;"
    });
alert("Sent2");
return false;
}

function UCMDBData(data, textStatus, jqXHR) {
    alert("Came back1");
    $(data).find('tns:CIs').each(function () {
        alert("Came back2");
        $(this).find("ns0:CI").each(function () {
            alert("Came back3");
            $("#output").append($(this).find("ns0:ID").text());
            document.AppServerForm.outputtext.value = document.AppServerForm.outputtext.value + "http://localhost:8080/ucmdb/cms/directAppletLogin.do?objectId=" + $(this).find('ns0:ID').text() +"&infopane=VISIBLE&navigation=true&cmd=ShowRelatedCIs&interfaceVersion=8.0.0&ApplicationMode=ITU&customerID=1&userName=admin&userPassword=admin";

    });
});

}

When I execute the only alert message i receive back is "Came back1" which means that the code is still not going through the xml properly with jquery. Any other suggestions?

Are you trying to match a single instance of ns0:CI, or can it appear more than once? — JesseBuesking

There is only a single instance of ns0:CI being returned as you can see in the XML response that I posted here also. — user1013396

The namespace-scoped names need to be handled a little differently. According to this answer: jQuery XML parsing with namespaces you would need to use an attribute selector [@nodeName=tns:CIs] instead.

You may need to drop the "@" for jQuery versions later than 1.3. Another suggestion is to escape the colon: .find('tns\:CIs'), which is hacky because it conflates the syntactic prefix with the semantic namespace (the uri). So if the prefix changed this method would break. A more correct answer will recognize the mapping of prefix to namespace uri. The jquery-xmlns plugin for namespace-aware selectors looks promising in that respect.

Actually I am still having issues, this is working in Firefox, but not IE 8 (Which is what is being used here).

The nodeName filter with namespace prefix no longer works in jQuery 1.7.

Turns out the IE issues are due to me connecting to the WSDL with authentication being passed in the url.. I.e. user:[email protected], in order to resolve this i need to do simple authentication in the XML (Soap) header.

For the record, what version of jQuery are you using, in which the solution worked?

Your jQuery success function is of the wrong form. It needs to be of the form

function UCMDBData(data, textStatus, jqXHR) {
    alert("Came back1");
    $(data).find('tns:CIs').each(function () {
        alert("Came back2");
        $(this).find("ns0:CI").each(function () {
            alert("Came back3");
            $("#output").append($(this).find("ns0:ID").text());
        });
    });
}

In addition, in your $.ajax function, change the contentType line to be contentType: "text/xml" instead of what you have before (assuming that you're sending XML to the server).

See the jQuery.ajax() documentation for more information.

Based on your comment, why do something crazy with jQuery? Just use javascript itself!

var open = '<ns0:ID>';
var close = '</ns0:ID>';

var start = obj.indexOf(open) + open.length;
var end = obj.indexOf(close);

var result = obj.slice(start, end);

Here's a jsfiddle that shows it in action.

It works with this specific example, but will break if the node has attributes.

Probably the right syntax would be

success: function(xml) {
    $(xml).find('tns:CIs').each(function() {
    ......
