Problemer med XML i JS
HejsaJeg laver et script hvor noget xml skal bearbejdes.
Jeg loader xml'en og laver domobject sådan:
if (window.DOMParser) {
parser = new DOMParser();
xmlDoc = parser.parseFromString(inputXml, "text/xml");
}
else // Internet Explorer
{
xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(inputXml);
}
Først hiver jeg køretøjer ud med:
var oXMLVehicleNodeList = xmlDoc.selectNodes("/ArrayOfvhc_vehicle/vhc_vehicle");
Dette virker fint. Men når jeg så forsøger at få crd_coodinates ud vil den ikke give mig noget tilbage:
var oXMLCoordinatesNodeList = xmlDoc.selectNodes("/vhc_vehicle/crd_coordinate/crd_coordinate");
alert(oXMLCoordinatesNodeList.length);
Jeg har tjekket det i xmlspy, og den giver mig det jeg ønsker. Min alert test returnere 0.
Min XML ser således ud:
