Hi all,
I'm trying to get the value of an XML file from an external server.
Below are the steps I do.
1/ I download this XML file with a classic Ajax request :
var getVesselsXML = new OpenLayers.Ajax.Request(
urlVessels,
{
method: 'get'
,onSuccess : drawVessels
,extractAttributes: true
}
);
The result of the request is :
"<POSITIONS>
<V_POS LAT="42.35675" LON="4.2338452" N="RED COUGAR" T="9" H="43"
S="53" F="ES" M="225350000" L="32" E="5" />
<V_POS LAT="42.532299" LON="4.35115" N="AQUAGLORY" T="7" H="217"
S="157" F="GR" M="240119000" L="289" E="2" />...
</POSITIONS>"
2/ In the drawVessels method I parse the result :
var XmlFormat = new OpenLayers.Format.XML();
vessels = XmlFormat.read(XmlvesselsRequest.responseText);
But I don't know how to get the attributes of a specific node. For
example, how can i Get the LON and the LAT of each node ?
I already tried somethings like that but it return me an empty string :
vessel = XmlFormat.getElementsByTagNameNS(vessels,'*','V_POS');
for (i in vessel){
var LAT = XmlFormat.getAttributeNS(vessel[i],'*','LAT');
console.log(LAT);
}
Thanks for your help
Best Regards
Arnaud
