Okay. I'll give you a rough example:
So, say you have an XML file datafile.xml with the following data:
<mydata>
<item>Herring</item>
<item>Ski-ball</item>
<item>Hornet leg</item>
<item>Pie</item>
<item>Femur of Michael Madsen</item>
</mydata>
In the Laszlo app, you could do:
<dataset name="randomThings" src="datafile.xml" type="http" request="true"/>
<datapointer name="randomDP" xpath="randomThings:/mydata" />
<method event="oninit">
var size = randomDP.getNodeCount();
for(var i = 1; i <= size; i++){
randomDP.setXPath('randomThings:/mydata[1]/item[' + i + ']');
randomDP.setNodeAttribute('num', i);
}
</method>
And then to reference (for instance):
randomDP.setXPath('randomThings:/mydata[1]/item[3]');
var position = randomDP.xpathQuery('@num');
position should equal 3.
