Answer 2

发生例外
org.apache.xerces.dom.DeferredTextImpl
其实下面有
<tab2><field type="2" len="10"> </tab2>
我只想读其中一个Tab

Answer 3

DocumentBuilderFactory documentbuilderfactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder documentbuilder = documentbuilderfactory.newDocumentBuilder();
           // InputStream is = getClass().getResourceAsStream(fileName);
            Document document = documentbuilder.parse(fileName);
            NodeList nodelist = document.getElementsByTagName(tabName);
            System.out.println("len is :" + nodelist.getLength());
            vector = new Vector();
            for(int i=0;i<nodelist.getLength();i++){               table =(Element)nodelist.item(i);
               childNodes = table.getElementsByTagName("field");
              
               for(int j=0;j<childNodes.getLength();j++){
                 field = (Element)childNodes.item(j);
                 type= field.getElementsByTagName("type").item(0).getFirstChild().getNodeValue();
                 name = field.getElementsByTagName("name").item(0).getFirstChild().getNodeValue();
                 title = field.getElementsByTagName("title").item(0).getFirstChild().getNodeValue();
                 isNull = field.getElementsByTagName("isNull").item(0).getFirstChild().getNodeValue();
                 isMainKey = field.getElementsByTagName("isMainKey").item(0).getFirstChild().getNodeValue();
                 len = field.getElementsByTagName("len").item(0).getFirstChild().getNodeValue();
                 isShow = field.getElementsByTagName("isShowInList").item(0).getFirstChild().getNodeValue();                 System.out.println("type,name,title,isnull,isMainKey,len is:" + type + "," + name + "," + title +
                                   "," + isNull + "," + isMainKey +"," + len );
