使用XPath Spring解析嵌入在另一个xml中的xml

我正在使用Xpath提供的“evaluate”函数解析xml字符串，以读取xml中特定标记中嵌入的内容。但是我在尝试解析嵌入在我想要解析的一组标记中的xml时遇到了问题

在上面的xml示例中，我需要读取和检索标记“param”中的所有内容。 目前，我首先获取param标记的计数，然后循环遍历它们以获取标记中的数据-

    paramCount = XPathUtils.evaluate(originalPayload,"count(/Channel/parameters/param)",XPathUtils.STRING);    
    for(int i=1;i<=pCount;i++){
          pList.add(XPathUtils.evaluate(originalPayload, "/Channel/parameters/param[" +i+ "]",XPathUtils.STRING)
            }

如果我删除部件“？xmlversion=“1.0”encoding=“UTF-8”？ 它解析标记，但输出为-

org.springframework.messaging.MessageHandlingException: HTTP request execution failed for URI [https://nike-dev.coupahost.com/api/suppliers?return_object=limited]; nested exception is org.springframework.web.client.HttpClientErrorException: 400 Bad Request


Unable to find valid PaymentTerm record for payment_term with keys {"code"=>"9999"}. Possible keys are ["id", "code"]. Please verify your xml.

如您所见，它只是捕获了各种标签中的内容并将其打印出来。 我的要求是打印两行之间的所有文本

有什么想法吗？

对于该任务，您在

中的内容必须包装到

中。否则它将成为根XML的一部分，并失去作为XPath结果的松弛数据的目的。
