Accessing attributes in xml using javascript

Question

Given the following xml, how do I access the record attributes in node, which is the 2nd record.

<?xml version="1.0" encoding="UTF-8" ?> 
- <dfs:myFields xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:q="http://schemas.microsoft.com/office/infopath/2003/ado/queryFields" xmlns:d="http://schemas.microsoft.com/office/infopath/2003/ado/dataFields" xmlns:dfs="http://schemas.microsoft.com/office/infopath/2003/dataFormSolution" xmlns:xdado="http://schemas.microsoft.com/office/infopath/2003/adomapping" xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2010-03-28T23:16:33" xmlns:xd="http://schemas.microsoft.com/office/infopath/2003" xml:lang="en-au" xdado:dataModified="" xmlns="">

  </dfs:queryFields>

<dfs:dataFields>

Best to use jquery ajax for this, in my opinion...

In Jquery Ajax it'd be something like the following:

$(document).ready(function(){
$.ajax({
    type: "GET",
    url: "../xml/yourxmlfile.xml", 
    dataType: "xml",
    success: function(xml) 
    {
        $(xml).find('nodename').each(function()
        {
            var attrvalue = $(this).attr('attributename');
            ...
            do what you want here
        }
    }
});
});

If you want to stick to plain javascript, you'd probably need to use regex.

Hope this helps

If you don't have jQuery and/or don't retrieve this with a controlled AJAX call then you can use:

var el = document.createElement("xml");
el.innerHTML = docData;  //xml content
var record = el.getElementsByTagName("d:Table1")[0];
var recor_builders_name = record.attributes["builders_name"].value;
document.write(recor_builders_name); //Do what you need with your record

Now, if you use an ajax call, but without jQuery, you can use the responseXML attribute from the call. That element is already a document object, so you can skip the first two lines and set el = yourAjax.responseXML instead (or use directly that attribute if you preferr)

Btw, I assume that xml is a fragment of a much bigger document and that the missing root node close-tag is just a copy-paste error.
