对xml中的节点<module name="test">添加属性节点为<module load="false" name="test">>

Java代码：

try {
   builder = factory.newDocumentBuilder();
} catch (ParserConfigurationException e1) {
   e1.printStackTrace();
}
try {
   inputDocument = builder.parse(new File(strFilename));
   outputDocument = builder.newDocument();
} catch (SAXException e1) {
   e1.printStackTrace();
} catch (IOException e1) {
   e1.printStackTrace();
}

Node moduleNode = strModuleList.get(i); //找到要修改的节点moduleNode
if (moduleNode.getNodeType() == Node.ELEMENT_NODE) {

    Element element = (Element) moduleNode;
    element.setAttribute("load", "false");//设置属性load="false"
    TransformerFactory factory = TransformerFactory.newInstance();
    Transformer former;
    try {
        former = factory.newTransformer();
        former.transform(new DOMSource(inputDocument), new StreamResult("xml文件路径"));
    } catch (TransformerConfigurationException e) {
        e.printStackTrace();
    } catch (TransformerException e) {
        e.printStackTrace();
    }
}
 ((Element) moduleNode).setAttribute("load","false");
 outputDocument.importNode(moduleNode, true);//写入xml文件
