c# - 如何向 SOAP XML 添加新元素

问题描述

我有一个 SOAP XML 文件名“LogEvents.xml”，我想从中添加/删除元素。

<?xml version="1.0" encoding="utf-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://www.w3.org/2001/12/soap-envelope" SOAP-ENV:encodingStyle="http://www.w3.org/2001/12/soap-encoding" >
  <SOAP-ENV:Body xmlns:lle="http://www.examplee.org/logevents" >

  <Event>
    <eventid>ID-1</eventid>
    <title>title1</title>
    <description>desc1</description>
    <location>
      <lat>1.357207</lat>
      <long>103.944880</long>
      <address>address1</address>
    </location>
    <datetimestamp>datetime1</datetimestamp>
  </Event>
  <Event>
    <eventid>ID-2</eventid>
    <title>title2</title>
    <description>desc2</description>
    <location>
      <lat>1.304121</lat>
      <long>103.831950</long>
      <address>addres2</address>
    </location>
    <datetimestamp>datetime2</datetimestamp>
  </Event>
    
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

下面显示了我尝试过但使用 Visual Studio 失败的代码。

XDocument xDoc1 = XDocument.Load(@"C:\LogEvents.xml");
                     

xDoc1.Element("SOAP-ENV").Add(new XElement("Event", new XElement("eventid", "strEventID"),
                                                    new XElement("title", "title2"),
                                                    new XElement("description", "desc3"),
                                                    new XElement("location", new XElement("lat", "lat3"),
                                                                             new XElement("long", "long3"),
                                                                             new XElement("address", "addresses3")),
                                                    new XElement("datetimestamp", "DateTime3")));

我试图删除 XML 文件中的 SOAP 信封并将其替换为“事件”并相应地编辑 C# 代码，它的工作原理如下所示。

<?xml version="1.0" encoding="utf-8"?>
<!--Changed to Events-->
<Events>
  <Event>
    <eventid>ID-1</eventid>
    <title>title1</title>
    <description>desc1</description>
    <location>
      <lat>1.357207</lat>
      <long>103.944880</long>
      <address>address1Edge</address>
    </location>
    <datetimestamp>datetime1</datetimestamp>
  </Event>
  <Event>
    <eventid>ID-2</eventid>
    <title>title2</title>
    <description>desc2</description>
    <location>
      <lat>1.304121</lat>
      <long>103.831950</long>
      <address>addres2</address>
    </location>
    <datetimestamp>datetime2</datetimestamp>
<!--Changed to Events-->
  </Event>
<Events>

XDocument xDoc1 = XDocument.Load(@"C:\LogEvents.xml");
                     
// Changed SOAP-ENV to Events
xDoc1.Element("Events").Add(new XElement("Event", new XElement("eventid", "ID-3"),
                                                    new XElement("title", "title3"),
                                                    new XElement("description", "desc3"),
                                                    new XElement("location", new XElement("lat", "lat3"),
                                                                             new XElement("long", "long3"),
                                                                             new XElement("address", "addresses3")),
                                                    new XElement("datetimestamp", "DateTime3")));

有什么方法可以忽略 SOAP 信封，或者有办法解决它吗？

解决方案

使用根。您始终可以在需要时从根目录获取默认命名空间。

           XDocument xDoc1 = XDocument.Load(FILENAME);
            XElement soap = xDoc1.Root;
            XNamespace ns = soap.GetDefaultNamespace();

            soap.Add(new XElement("Event", new XElement("eventid", "strEventID"),
                                                    new XElement("title", "title2"),
                                                    new XElement("description", "desc3"),
                                                    new XElement("location", new XElement("lat", "lat3"),
                                                                             new XElement("long", "long3"),
                                                                             new XElement("address", "addresses3")),
                                                    new XElement("datetimestamp", "DateTime3")));
