上面是这个程序用到的XML，实际上这个方法的传入参数是个URL，这个URL在浏览器中取得的结果就是上面的XML。
private void parseURL(String strURL) {
try {
String[] strLID = null;
URL url = new URL(strURL);
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setValidating(false);
DocumentBuilder doc_builder = dbf.newDocumentBuilder();
Document doc = doc_builder.parse(new InputSource(new InputStreamReader(url.openStream(),"SHIFT-JIS")));
//Get root node
Element rootElement = doc.getDocumentElement();
if (rootElement == null){
return;
}
NodeList paramNodeLists = doc.getElementsByTagName("LID");
int iNodeCount = paramNodeLists.getLength();
strLID = new String[iNodeCount];
for (int i = 0; i < iNodeCount; i++) {
strLID[i] = paramNodeLists.item(i).getFirstChild().getNodeValue().trim();
System.out.println(“[“ + strLID[i] + “]“);
}
this.strLID = strLID;
}
catch (Exception e) {
this.strLID = null;
return;
}
}
运行结果为：
