Question

我再次遇到一个XML文档的问题，我收到的是Web请求（HP Service Manager）的响应。

这是XML响应：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">

</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

我尝试使用以下代码，但最后我通过循环现有节点。我知道应该有一种简单的方法来从节点“实例”和所有子项中获取所有项目。

最后，我需要一个DataView或DataTable继续我的应用程序。

public static string gettextfromWebserviceItems(string result)
    {
        StringBuilder builder = new StringBuilder();


        var doc = new XmlDocument();
        doc.LoadXml(result);
        var ns = new XmlNamespaceManager(doc.NameTable);
        ns.AddNamespace("SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/");
        //XmlNodeList nodes = doc.SelectNodes("/SOAP-ENV:Envelope/SOAP-ENV:Body/RetrieveSDToDoListResponse/instance", ns);
        XmlNodeList nodes = doc.GetElementsByTagName("instance");

        List<string> elementNamesList = new List<string>();
        elementNamesList.Add("TodoNumber");
        elementNamesList.Add("ToDoModule");
        elementNamesList.Add("ToDoStatus");
        elementNamesList.Add("ToDoDescription");
        elementNamesList.Add("ToDoAssignmentGroup");
        elementNamesList.Add("ToDoAssigneeName");

        foreach (XmlNodeList node in nodes)
        {

            //foreach (XmlAttribute v in node.Attributes)
            //{
            //    var value = v;
            //    //Do the processing

            //}


        }

如果有一个像SAX这样的外部DLL的简单解决方案，那么请告诉我......

提前谢谢你，来自慕尼黑的祝福

XSD文件可以相对容易地转换为C＃类定义。您发布的XML中包含以下属性：xsi:schemaLocation="http://schemas.hp.com/SM/7 /SDToDo.xsd"。

使用此功能，您可以使用xsd.exe将XSD解析为C＃，以便与XmlSerializer一起使用（这是一个糟糕的主意，我也不会这样做），或者您可以使用C＃类作为在不使用XmlSerializer的情况下创建自己的模型和翻译器的基础（使用XNode而不是XmlDocument API）。

一旦它以对象形式出现，就可以相对轻松地变成DataTable或DataView（或者您可以直接进行，无论您喜欢哪种方式）。< / p>

与前面的发言者不太一致。是的，它将以对象形式出现，但将对象数组转换为DataTable并不容易。在你的情况下你很幸运你的信封，xml是DataTable xml格式的精确表示，你可以只使用ReadXml方法

// your code, practically unchanged
XmlDocument doc = new XmlDocument();
doc.LoadXml(result);
XmlNamespaceManager ns = new XmlNamespaceManager(doc.NameTable);
ns.AddNamespace("SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/");
ns.AddNamespace("XZ", "http://schemas.hp.com/SM/7");
XmlNode node = doc.SelectSingleNode("SOAP-ENV:Envelope/SOAP-ENV:Body/XZ:RetrieveSDToDoListResponse", ns);

if(node!=null)
{
    //define your table
    DataTable dt = new DataTable();
    dt.Columns.Add("TodoNumber", typeof(string));
    dt.Columns.Add("ToDoModule", typeof(string));
    dt.Columns.Add("ToDoStatus", typeof(string));
    dt.Columns.Add("ToDoDescription", typeof(string));
    dt.Columns.Add("ToDoAssignmentGroup", typeof(string));
    dt.Columns.Add("ToDoAssigneeName", typeof(string));
    dt.TableName = "instance";

    string content = "<DocumentElement>" +
        //DIRTY HACK TO REMOVE NAMESPACE
            node.InnerXml.Replace("xmlns=\"http://schemas.hp.com/SM/7\"", "")
         + "</DocumentElement>";

    //this code makes the trick
    using(MemoryStream  ms=new MemoryStream(Encoding.UTF8.GetBytes (content)))
    {
        dt.ReadXml(ms);    
    }

}

如何正确处理此XML响应（SOAP：Envelope）以获取至少一个DataView / DataTable？
