Parsing complex XML Tags with QML

[belhawary]

I wanna parse RSS feed with QML.

the feed structure looks like

<channel>
    <item>
    <title>
    </title>
    <description>
    </description>
    <media:content url="http://someURLHere.com/avatar/somethingHere?s=96&#38;d=identicon&#38;r=G" medium="image">
    </media:content>
    </item>

my problem is with the <media:content> tag, how can i parse the url with QML into a string ?

Hi,
You can use JS to parse XML.
Here is an example which show you how to get tag attributes;

<fruits>
<fruit name="Apple" colour="Green" />
<fruit name="Banana" colour="Yellow" />
</fruits>
JavaScript:

function getFruits(xml) {
var fruits = xml.getElementsByTagName("fruits")[0];
if (fruits) {
var fruitsNodes = fruits.childNodes;
if (fruitsNodes) {
for (var i = 0; i < fruitsNodes.length; i++) {
var name = fruitsNodes[i].getAttribute("name");
var colour = fruitsNodes[i].getAttribute("colour");
alert("Fruit " + name + " is coloured " + colour);
}
}
}
}

what is meant by xml in getFruits(xml) ?
is it the feed url ?

xml is a string

Thanks gnuton.

I figured another solution with QML without need for Javascript
we just declare media namespace

for example the code will look like

 
XmlListModel {
namespaceDeclarations: "declare namespace media = 'http://search.yahoo.com/mrss/'; declare 
namespace default = 'http://rss.news.yahoo.com/rss/world';"
.
.
.
.
XmlRole { name: "img"; query: "media:content/@url/string()" }
}

I hope this is helpful for anyone who needs it later
