Parse xml with namespaces using JQuery and working for all browser ..

Question

I'm trying to parse an XML response from a service using JQuery 1.11

At the moment my code works but only in Chrome, not for IE or Firefox and I need it works for all "modern" browsers.

Here you are a sample of my XML

<?xml version='1.0' encoding="ISO-8859-1" ?>
<wfs:FeatureCollection
   xmlns:ms="http://mapserver.gis.umn.edu/mapserver"
   xmlns:wfs="http://www.opengis.net/wfs"

        <ms:id>13800026457290</ms:id>

        <ms:civico>25</ms:civico>
        <ms:istat>01004041</ms:istat>

        <ms:cap>12030</ms:cap>
        <ms:comune>CARAMAGNA PIEMONTE</ms:comune>
        <ms:nome_ted> </ms:nome_ted>
        <ms:provincia>CUNEO</ms:provincia>
        <ms:regione>PIEMONTE</ms:regione>
      </ms:IN.NUMERICIVICI.2012>

    </gml:featureMember>

Here you are my code

var xmlText = $('#featureData').text(),
$xmlData = $.parseXML(xmlText),
$features = $('featureMember', $xmlData),
extractedFeatures = [];

$features.each(function () {
var $this = $(this),
    feature = {},
    items = [
        'nome',
        'civico',
        'istat',
        'cap',
        'comune'
    ],
    item;

for (var i = 0; i < items.length; i++) {
    item = items[i];
    feature[item] = $this.find(item).text();
}

extractedFeatures.push(feature);
});

$('#output').text(JSON.stringify(extractedFeatures));

and here you are my jsfiddle so you can try it

Any suggestion or workaround? Thank you very much in advance ...

You have to be careful with namespaces... if you work with XML that has some namespaces declaration you have to keep it in mind and build appropriate selectors.

For example:

$features = $('gml\\:featureMember, featureMember', $xmlData),

Please take a look on update fiddle. Now it works in FF and IE as well.

I need for an addendum ... Which notation I've to use for extract values of coordinates in my original sample XML <gml:Point srsName="EPSG:4326"> <gml:coordinates>7.735138,44.810267</gml:coordinates> </gml:Point> Thanks a lot!

This didn't worked for me, but I've found a working solution here:

http://jamesmcdonald.id.au/it-tips/google-chrome-xml-namespaces On above page we can find this:

$(xml).find('ns1\\:ld_det, ld_det');

Where 'ns1' is namespace such as gml, and 'ld_let' is node name.

And it works in Google Chrome too.

In case if someone is facing issues parsing XML with namespaces in MS Edge browser, here is the workaround:

$.fn.filterNodeByPrefix = function(prefix) {
    return this.filter(function() {
        return this.prefix === prefix;
    });
};

We can use this function as:

$('gml\\:featureMember, featureMember', $xmlData).filterNodeByPrefix('gml');

Tried and tested in Chrome, FF, IE and MS Edge.
