java如何从soap响应中提取相同元素类型的列表？

Question

如何从下面的XML中提取所有“BalDtoList”元素，例如从下面的soap响应中提取列表中的元素

<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
    <ns:QueryAcctBal
        xmlns:ns="">
        <BalDtoList>
            <BalID>105529650</BalID>
            <AcctResID>1</AcctResID>
            <BalType>3</BalType>
            <Balance>9363</Balance>
            <EffDate>2014-04-30 15:24:31</EffDate>
        </BalDtoList>
        <BalDtoList>
            <BalID>2100000425</BalID>
            <AcctResID>5025</AcctResID>
            <BalType>1</BalType>
            <Balance>4560</Balance>
            <EffDate>2019-11-29 04:10:36</EffDate>
        </BalDtoList>
        <BalDtoList>
            <BalID>2100000413</BalID>
            <AcctResID>5008</AcctResID>
            <BalType>1</BalType>
            <Balance>60</Balance>
            <EffDate>2019-11-29 04:10:36</EffDate>
        </BalDtoList>
        <BalDtoList>
            <BalID>2100000401</BalID>
            <AcctResID>5011</AcctResID>
            <BalType>9</BalType>
            <Balance>80</Balance>
            <EffDate>2019-11-29 04:10:36</EffDate>
        </BalDtoList>
        <ResultMsg>success</ResultMsg>
    </ns:QueryAcctBal>
</soapenv:Body>

下面是我的代码函数，在这里我从SOAP消息中提取属性

    public static void ExtractingWalletInfo(String message,String mobno) {
    try {

        InputStream is = new ByteArrayInputStream(message.getBytes());
        SOAPMessage respMsg = MessageFactory.newInstance().createMessage(null, is);
        SOAPBody body = respMsg.getSOAPBody();
        NodeList Bal = body.getElementsByTagName("BalDtoList");

    }catch(Exception e){
        e.printStackTrace();
    }

}

Answer 1

Web服务客户端（SOAP）

如果必须访问SOAPweb服务接口，请使用JAX-WS（随JDK提供，jdk/bin/wsimport）、Apache Axis、Apache CXF或其他框架来生成web服务客户端

解析XML

如果您没有访问SOAP接口的权限，但只是尝试解析XML文档（如SOAP信封），请使用DocumentBuilder，例如：

DocumentBuilder documentBuilder =
    DocumentBuilderFactory.newInstance().newDocumentBuilder();
Reader in = new StringReader(message);
Document document = documentBuilder.parse(new InputSource(in));
in.close();
NodeList nodes = document.getElementsByTagName("BalDtoList");
for(int i = 0; i < nodes.getLength(); i++) {
    Element elem = (Element) nodes.item(i);
    System.out.println(i + ":");
    for (String name : new String[] {
        "BalID", "AcctResID", "BalType", "Balance", "EffDate"
    }) {
        String value = elem.getElementsByTagName(name).item(0).getTextContent();
        System.out.println(name + " = " + value);
    }
}

输出是

0:
BalID = 105529650
AcctResID = 1
BalType = 3
Balance = 9363
EffDate = 2014-04-30 15:24:31
1:
BalID = 2100000425
AcctResID = 5025
BalType = 1
Balance = 4560
EffDate = 2019-11-29 04:10:36
...

顺便说一句，您的XML文档无效，因为它缺少根元素的结束标记</soapenv:Envelope>
