这是我的 xml 代码。到目前为止，我已经编写了 xslt 代码

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:cs="urn:cs" xmlns:msxsl="urn:schemas-microsoft-com:xslt" version="1.0" exclude-result-prefixes="msxsl cs">
   <xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
   <msxsl:script language="C#" implements-prefix="cs">
      <msxsl:assembly name="System.Web.Extensions" />
      <msxsl:using namespace="System.Collections.Generic" />
      <msxsl:using namespace="System.Web.Script.Serialization" />
      <![CDATA[public string getXMLFromJson(string jsonString)
      string resp="";
      var serializer = new javascriptSerializer();
      Dictionary<string, object> result = (serializer.DeserializeObject(jsonString) as Dictionary<string, object>);    
      foreach(string key in result.Keys)
        var newKey=key.Replace(" ","_");
        resp+="<"+newKey+">"+result[key]+"</"+newKey+">";
        
            return resp;
    ]]>
   </msxsl:script>
   <xsl:template match="@* | node()">
      <xsl:copy>
         <xsl:apply-templates select="@* | node()" />
      </xsl:copy>
   </xsl:template>
   <xsl:template match="root/dataResponse">
      <xsl:variable name="jstr">
         <xsl:value-of select="." />
      </xsl:variable>
      <dataResponse>
         <xsl:value-of select="cs:getXMLFromJson($jstr)" disable-output-escaping="yes" />
      </dataResponse>
   </xsl:template>
</xsl:stylesheet>

我无法遍历嵌套对象 resultsInformation 并且还想要循环 addressInformation 并将其转换为 xml。我当前的输出如下所示。

    <root>
  <dataResponse><status>C</status><responseCode>200</responseCode><description>Success</description><resultsInformation>System.Object[]</resultsInformation></dataResponse>
  <message>Request Completed Successfully</message>
  <statusCode>000</statusCode>
  <status>Success</status>
</root>

【问题讨论】：

我什至不知道您可以在 xslt 中注入 C# 代码...您可以发布代码以使 franken-xslt 运行吗？ 我可以建议你“提取”C#代码，至少是为了调试它......最后你知道输入是什么（json）和输出应该是什么（一个 xml 片段）。 xslt 只是额外的包袱，它会使所有的调试变得更加复杂。 如果你可以使用 json.net 就很容易了：***.com/questions/18503845/… 【参考方案1】：

如果你可以使用 Json.Net，它就变成了单线：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:cs="urn:cs" xmlns:msxsl="urn:schemas-microsoft-com:xslt" version="1.0" exclude-result-prefixes="msxsl cs">
    <xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />
    <xsl:strip-space elements="*"/>
    <msxsl:script language="C#" implements-prefix="cs">
        <msxsl:assembly name="System.Xml.Linq" />
        <msxsl:using namespace="Newtonsoft.Json" />
        <msxsl:assembly name="Newtonsoft.Json" />
        <msxsl:using namespace="System.Xml.Linq" />
        <![CDATA[
        public static XPathNavigator getXMLFromJson(string jsonString)
        
            var xml = JsonConvert.DeserializeXmlNode(jsonString, "dataResponse");
            return xml.CreateNavigator();
        
        ]]>
    </msxsl:script>
    <xsl:template match="@* | node()">
        <xsl:copy>
            <xsl:apply-templates select="@* | node()" />
        </xsl:copy>
    </xsl:template>
    <xsl:template match="root/dataResponse">
        <xsl:copy-of select="cs:getXMLFromJson(.)" />
    </xsl:template>
</xsl:stylesheet>

请注意，我添加了一个

<xsl:strip-space elements="*"/>

正确格式化生成的 xml。

如果没有 Json.Net，它会复杂得多（我不确定是否涵盖了所有极端情况）：

    <xsl:strip-space elements="*"/>

                return xml.CreateNavigator();
