XPathExpression#evalute will return a NodeList if you use XPathConstants.NODESET.

Once you have the NodeList, you will need to iterate the list and populate your array...

NodeList nodeList = (NodeList)xPath1.compile("/place/native[@name]").evaluate(xmlDocument, XPathConstants.NODESET);
String[] results = new String[nodeList.getLength()];
for (int index = 0; index < nodeList.getLength(); index++) {
    Node node = nodeList.item(index);
    String name = node.getAttributes().getNamedItem("name");
    results[index] = name;
}

The problem is (from my testing), evalute(xmlDocument) is only return the first match, where as the example I posted returns all of them...
