c# - 如何在 C# 中编辑和保存 abc.testsettings(xml) 文件

Question

我有以下内容的文件。我想删除 DeploymentItem 下的所有元素并创建新的。

<?xml version="1.0" encoding="UTF-8"?>
<TestSettings name="Settings" id="6f67be45-4967-40c3-a89f7665cc7f654e2" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">
  <Description>These are default test settings for a local test run.</Description>
  <Deployment>
<DeploymentItem filename="TestCaseXml\LTestCases.xml" />
<DeploymentItem filename="..\..\Framework\Common\Xmls\TestSuite.xml" />
<DeploymentItem filename="TestCaseXml\bTestCases.xml" />
<DeploymentItem filename="TestCaseXml\PTestCases.xml" />
<DeploymentItem filename="TestCaseXml\1TestCases.xml" />
</Deployment>
</TestSettings>

当我使用下面的代码时，它会给我下面给出的输出

XmlDocument doc2 = new XmlDocument();
            doc2.Load(testBinaryFile);
foreach (XmlNode node in doc2.DocumentElement.ChildNodes)
                {
                if (node.Name == "Deployment")
                {
                    node.RemoveAll();

                    foreach(string element in Folders)
                    {
                        if(!element.Contains("Scripts"))
                        {
                            string[] Files7 = Directory.GetFiles(element);
                            foreach(string File2 in Files7)
                            {
                                string addName = File2.Substring(File2.LastIndexOf(@"TestBinaries\")).Replace("TestBinaries\\", "");
                                XmlElement elem = doc2.CreateElement("DeploymentItem");
                                elem.InnerText = "filename='" +  addName + "'";
                                node.AppendChild(elem);
                            }

                        }
                        else
                        {
                            string addName = element.Substring(element.LastIndexOf("TestBinaries\\")).Replace("TestBinaries\\","") + "\\";
                            XmlElement elem = doc2.CreateElement("DeploymentItem");
                            elem.InnerText = @"filename='" + addName + "'";
                            node.AppendChild(elem);
                        }
                    }

                    doc2.Save(testBinaryFile);
                }   



<?xml version="1.0" encoding="UTF-8"?>
<TestSettings name="Settings" id="6f67be45-4967-40c3-a89f7665cc7f654e2" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">
  <Description>These are default test settings for a local test run.</Description>
  <Deployment>
<DeploymentItem xmlns="">filename='Scripts\'</DeploymentItem>
<DeploymentItem xmlns="">filename='TestCaseXml\bTestCases.xml'</DeploymentItem>
<DeploymentItem xmlns="">filename='Xmls\TestSuite.xml'</DeploymentItem>
  </Deployment>
</TestSettings>

我想要如下所示的输出。请帮忙。

<?xml version="1.0" encoding="UTF-8"?>
<TestSettings name="Settings" id="6f67be45-4967-40c3-a89f7665cc7f654e2" xmlns="http://microsoft.com/schemas/VisualStudio/TeamTest/2010">

<DeploymentItem filename='TestCaseXml\bTestCases.xml' />
<DeploymentItem filename='Xmls\TestSuite.xml' />
  </Deployment>
</TestSettings>

关于将 xmlns="" 添加到新元素，那是因为您的 XML 具有默认 namespace 。请注意，在 XML 中，后代元素隐式继承祖先的默认 namespace ，除非另有说明。

也就是说，在您发布的预期输出中，DeploymentItem 位于默认命名空间 “http://microsoft.com/schemas/VisualStudio/TeamTest/2010” 中。

您可以使用 CreateElement() overload它接受前缀、localName、namespaceURI 参数以在命名空间中创建元素。具体来说，尝试替换这一行:

XmlElement elem = doc2.CreateElement("DeploymentItem");

用这个:

XmlElement elem = doc2.CreateElement(
                            string.Empty, 
                            "DeploymentItem", 
                            "http://microsoft.com/schemas/VisualStudio/TeamTest/2010"
                      );
