Question

我正在使用parse xml尝试jsoup数据。我将每个数据都放入array list。但是，当我得到data时，每个data都会进入同一行。例如，我得到的数据是

RESULT
    ITEM
    R1
      B DESC =""
        B1
      C DESC =""
        CR1
           C1
        CR2
           C1
        CR3
           C1

我的java代码是

List<Object> list = new ArrayList<>();            
Elements elements = document.select("ITEM");
for (Element element : elements) {
   medicationBasic = new MedicationBasic();
   medicationBasic.setProductName(element.select("B1").text());
   medicationOrigin = new MedicationOrigin();
   medicationOrigin.setMedOrigin(element.select("C1").text());
   list.add(medicationBasic);
   list.add(medicationOrigin);
   response = new ResponseList(Result.SUCCESS, (ArrayList) list);

我得到的是：

{
productName:"B1",
medOrigin:"C1(from CR1) C1(from CR2) C1(from CR3)"
}

预期结果：

{
productName:"B1",
medOrigin:"C1(from CR1)"
}

{
productName:"B1",
medOrigin:"C1(from CR2)"
}

{
productName:"B1",
medOrigin:"C1(from CR3)"
}

我的代码出了什么问题？请帮帮我...

Answer 1

element.select("C1")选择ITEM内的所有C1元素（返回Elements），text()返回combined text：

public String text（）获取所有匹配的组合文本元件。

<强>修正迭代C1元素并添加键值对。

示例代码

String xmlString = "<RESULT>\r\n" + 
        "    <ITEM>\r\n" + 
        "       <R1>\r\n" + 
        "           <B DESC =\"\">\r\n" + 
        "               <B1>B1<B1>\r\n" + 
        "           </B>\r\n" + 
        "           <C DESC =\"\">\r\n" + 
        "               <CR1>\r\n" + 
        "                   <C1>C1(from CR1)</C1>\r\n" + 
        "               </CR1>\r\n" + 
        "               <CR2>\r\n" + 
        "                   <C1>C1(from CR2)</C1>\r\n" + 
        "               </CR2>\r\n" + 
        "               <CR3>\r\n" + 
        "                   <C1>C1(from CR3)</C1>\r\n" + 
        "               </CR3>\r\n" + 
        "           </C>\r\n" + 
        "       </R1>\r\n" + 
        "   </ITEM>\r\n" + 
        "</RESULT>";

Document document = Jsoup.parse(xmlString);

List<SimpleEntry<String, String>> list = new ArrayList<>();

Elements elements = document.select("ITEM");
for (Element element : elements) {
    String medicationBasic = element.select("B1").text();
    element.select("C1").forEach(c1Element -> {
        String medicationOrigin = c1Element.text();
        list.add(new SimpleEntry<String, String>(medicationBasic, medicationOrigin));

    });
}

System.out.println(list);

<强>输出

[B1 =C1(from CR1), B1 =C1(from CR2), B1 =C1(from CR3)]

Answer 2

为了将来的参考，我通过以下方式解决了我的问题：

List<Object> list = new ArrayList<>();            
Elements bElement = document.select("B DESC");
Elements cElement = document.select("C DESC>*");
for (Element bElement : elements) {
   medicationBasic = new MedicationBasic();
   medicationBasic.setProductName(element.select("B1").text());
   list.add(medicationBasic);
}
for (Element cElement : elements) {
   medicationOrigin = new MedicationOrigin();
   medicationOrigin.setMedOrigin(element.select("C1").text());
   list.add(medicationOrigin);
}
response = new ResponseList(Result.SUCCESS, (ArrayList) list);

我得到了我期望的结果
