java - 当存在重复标签时，在JAVA中解析XML

Question

我需要从下面的 xml 中读取值，并为此使用 saxparser，但是在读取标签时卡住了，它出现了多次，并且我无法读取下一行标签，任何人都可以帮助我......？

整个数据出现在标签之间，并引用不同的表，标签给出了需要插入的记录集，并引用了需要插入到该特定列的列名和值。

 <?xml version="1.0" encoding="UTF-8"?>

<TABLEDATA name="web_order_header" rows="1">

这是我的JAVA代码

public void readXml(Document requestDoc,PrintStream out)throws IOException, JDOMException, SQLException, ParseException {
             Document responseDoc = null;


             Element root = requestDoc.getRootElement();

             List tableNameList = root.getChildren("TABLEDATA");

             for(int i=0; i<tableNameList.size(); i++){
                 Element table = (Element) tableNameList.get(i);
                 String tableName = table.getAttribute("name").getValue();
                 int numOfRows = table.getAttribute("rows").getIntValue();
                 System.out.println(tableName+" : tableName---------------------- numOfRows : "+numOfRows);

                    List rowList = root.getChild("TABLEDATA").getChildren("ROW");
                    for(int j=0; j<rowList.size(); j++){
                        Element row = (Element) rowList.get(j);
                        System.out.println("row : "+rowList.size());

                        List fieldList =  root.getChild("TABLEDATA").getChild("ROW").getChildren("FIELD");
                        System.out.println("----------------------");
                        for(int k=0; k<fieldList.size(); k++){
                            Element field = (Element) fieldList.get(k);
                            String fieldName = field.getAttribute("name").getValue();
                            String fieldValue = field.getTextTrim();
                            System.out.println(fieldName+"----------------------"+fieldValue);
                        }
                        System.out.println("----------------------");
                    }


             }

Answer 1

您总是看着第一个表和第一行。要修复此问题，请使用 for 循环中的当前元素。

替换

List rowList = root.getChild("TABLEDATA").getChildren("ROW");

与

List rowList = table.getChildren("ROW");

和

List fieldList =  root.getChild("TABLEDATA").getChild("ROW").getChildren("FIELD");

与

List fieldList =  row.getChildren("FIELD");
