Question

我只是尝试解析SOAP响应并从以下XML中提取 ResponseCode 和 UnconfirmedReasonCode 元素：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <CoverageResponse xmlns="http://www.iicmva.com/CoverageVerification/">
      <Detail>
        <PolicyInformation>
          <CoverageStatus>
            <ResponseDetails>
              <ResponseCode>CONFIRMED</ResponseCode>
              <UnconfirmedReasonCode/>
            </ResponseDetails>
          </CoverageStatus>
        </PolicyInformation>
      </Detail>
    </CoverageResponse>
  </soap:Body>
</soap:Envelope>

我一直在尝试做的事情不起作用：

Dim doc As New XmlDocument
doc.LoadXml(result)

Dim root = doc.DocumentElement.FirstChild.FirstChild
Dim responseDetails = root.SelectSingleNode("descendant::Detail/PolicyInformation/CoverageStatus/ResponseDetails")
Dim responseCode = responseDetails.ChildNodes(0).InnerText
Dim unconfirmedReasonCode = responseDetails.ChildNodes(1).InnerText

Console.WriteLine("Response Details:" & vbCrLf & vbCrLf & responseCode & " " & unconfirmedReasonCode)
Console.ReadLine()

这是关于选择具有默认命名空间的XML文档元素的最常见问题 - 请搜索XPath和默认命名空间。提示：了解XmlNamespaceManager类。

一种相对简单且不易阅读的选择方法：

使用：

/*/*/*/*/*/*/*/*[local-name()='ResponseCode']

并使用：

/*/*/*/*/*/*/*/*[local-name()='UnconfirmedReasonCode']

基于XSLT的验证：

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/">
  <xsl:copy-of select=
  "/*/*/*/*/*/*/*/*[local-name()='ResponseCode']"/>
  <xsl:copy-of select=
  "/*/*/*/*/*/*/*/*[local-name()='UnconfirmedReasonCode']"/>
 </xsl:template>
</xsl:stylesheet>

将此转换应用于提供的XML文档：

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:Body>
    <CoverageResponse xmlns="http://www.iicmva.com/CoverageVerification/">
      <Detail>
        <PolicyInformation>
          <CoverageStatus>
            <ResponseDetails>
              <ResponseCode>CONFIRMED</ResponseCode>
              <UnconfirmedReasonCode/>
            </ResponseDetails>
          </CoverageStatus>
        </PolicyInformation>
      </Detail>
    </CoverageResponse>
  </soap:Body>
</soap:Envelope>

输出两个正确选择的节点：

<ResponseCode xmlns="http://www.iicmva.com/CoverageVerification/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">CONFIRMED</ResponseCode>
<UnconfirmedReasonCode xmlns="http://www.iicmva.com/CoverageVerification/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" />

无法使用xPath选择单个节点
