从节点列表java

Question

我的xml看起来像这样

<?xml version="1.0"?>
<config>
<string name="string1">anything</string>
<string name="string2">anything</string>
<boolean name="bool1" value="true" />
 <boolean name="bool2" value="true" />
<long name="long1" value="1444444444" />
<long name="long2" value="1444444444" />
<long name="long3" value="1444444444" />
</config>

我正在使用nodeList

  try {
                    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
                    DocumentBuilder db = dbf.newDocumentBuilder();
                    Document document = db.parse(new File("filelocation"));
                    NodeList nodeList = document.getElementsByTagName("string");
                    for(int x=0,size= nodeList.getLength(); x<size; x++) {
                        String sssss = nodeList.item(x).getAttributes().getNamedItem("name").getNodeValue();
                        if (sssss.equals("string2")){

                        Node node = nodeList.item(x);
                        node.getParentNode().removeChild(node);

                           // i get here i need to remove string 2 and set some value of string 1 and long1 how can i do it ?
                        }
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }

因此应删除string2并编辑long1和string 1的值 所以删除字符串2不起作用
