我想解析这个xml文件，其中所有节点的名称都相似。

虽然我尝试并使用下面的代码
SAXBuilder builder = new SAXBuilder();
File xmlFile = new File("C:\\Users\\amishr33\\screen_dump1.uix");
Properties btn_bound = new Properties();
try {
Document document = (Document) builder.build(xmlFile);
Element rootNode = document.getRootElement();
Element element = rootNode.getChild("node");
Element element1 = element.getChild("node");
Element element2 = element1.getChild("node");
Element element3 = element2.getChild("node");
List list = element3.getChildren("node");
for (int i = 0; i < list.size(); i++) {
Element node = (Element) list.get(i);
Attribute value = node.getAttribute("class");
if ((value.getValue().toString()).compareTo("android.widget.LinearLayout")==0) {
List list1 = node.getChildren("node");
for (int j = 0; j < list1.size(); j++) {
Element node1 = (Element) list1.get(j);
Attribute value1 = node1.getAttribute("class");
if ((value1.getValue().toString()).compareTo("android.widget.LinearLayout")==0) {
List list2 = node1.getChildren("node");
for (int k = 0; k < list2.size(); k++) {
Element node2 = (Element) list2.get(k);
Attribute class1 = node2.getAttribute("class");
Attribute text1 = node2.getAttribute("text");
Attribute bounds1 = node2.getAttribute("bounds");
btn_bound.put(new String(class1.getValue()+"."+text1.getValue()), bounds1.getValue());
}
}else{
Attribute class1 = node1.getAttribute("class");
Attribute text1 = node1.getAttribute("text");
Attribute bounds1 = node1.getAttribute("bounds");
btn_bound.put(new String(class1.getValue()+"."+text1.getValue()), bounds1.getValue());
}
}
}
}
} catch (IOException io) {
System.out.println(io.getMessage());
} catch (JDOMException jdomex) {
System.out.println(jdomex.getMessage());
}
但它仅对此xml文件/屏幕转储非常具体。如何使这个解析器通用？我试图通过文本属性和类属性的组合来按顺序排列它们。
答案 0 :(得分：1)
我进一步尝试并发现jdom解析器是SAX paresr的更好替代品。
try {
File inputFile = new File(value);
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(inputFile);
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("node");
for (int temp = 0; temp < nList.getLength(); temp++) {
Node nNode = nList.item(temp);
if (nNode.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) nNode;
if(eElement.getAttribute("class").toString().compareTo("android.widget.Button")==0)
{
btn_bound.put(new String(eElement.getAttribute("resource-id")), eElement.getAttribute("bounds"));
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
