.text() method in jQuery not working for xml element for some reason

I have the following javascript:

function getMessageFromXML(xml) {
    alert('xml: ' + xml);
    alert("Text of message: " + $(xml).find('dataModelResponse').find('adminMessage').text());
    return $(xml).find('dataModelResponse').开发者_JS百科find('adminMessage').text();
}

which is being executed on the following XML:

<dataModelResponse>
  <adminMessage>BARF</adminMessage>
  <adminData>
    <identifier>123456</identifier>
  </adminData>
</dataModelResponse>

I know that the XML is correctly passed in, because of the first alert, but the message is showing up as blank for some reason. I verified that there were exactly 1 message and 1 dataModelResponse elements in the xml, using the .length modifier for similar find() queries, but for some reason, I can't get it to print out the correct message.

Suggestions?

EDIT: Changed the tag name I was searching for. Posted in between two revisions, sorry.

Replace $(xml).find('dataModelResponse').find('message').text(); with $(xml).find('message').text();.

The documentation for jQuery.find() states:

Get the descendants of each element in the current set of matched elements, filtered by a selector.

The root level element of your XML block is dataModelResponse. By calling $(xml).find('dataModelResponse'), you are essentially asking for a dataModelResponse within your dataModelResponse.

After $(xml) you’re already on the root node, which is dataModelResponse. Thus you will not find any child-elements of type dataModelResponse, and thus text() will return nothing.

Concrete:

console.log("Text of message: " + $(xml).text());

Will log

Text of message: BARF 123456 

And (this is what you want)

console.log("Text of message: " + $(xml).find('message').text());

will log

Text of message: BARF

And

console.log("Text of message: " + $(xml).find('dataModelResponse').text());

will log

Text of message: 

Should it be 'adminMessage' instead?

If you are using jQuery 1.5, you can write:

alert("Text of message: " + $($.parseXML(xml)).find('adminMessage').text());

or

alert("Text of message: " + $($.parseXML(xml)).find('dataModelResponse > adminMessage').text());  

or

alert("Text of message: " + $($.parseXML(xml)).find('dataModelResponse').find('adminMessage').text());
