在编写.net绑定之前，我正在编写一个解析工具来帮助我清理一个大型VC ++项目。
我正在使用XML编写器读取xml文件并将每个元素写出到新文件中。如果找到具有特定名称的元素，则它执行一些代码并将输出值写入元素值。
到目前为止它几乎正常工作，除了一件事：它不是复制属性。谁能告诉我为什么会这样？
以下是应该复制/修改内容的示例（包括属性）：
<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<ItemGroup Label="ProjectConfigurations">
<ProjectConfiguration Include="Debug|Win32">
<Configuration>Debug</Configuration>
<Platform>Win32</Platform>
</ProjectConfiguration>
<ProjectConfiguration Include="Release|Win32">
<Configuration>Release</Configuration>
<Platform>Win32</Platform>
</ProjectConfiguration>
</ItemGroup>
<PropertyGroup Label="Globals">
<ProjectGuid>{57900E99-A405-49F4-83B2-0254117D041B}</ProjectGuid>
<Keyword>Win32Proj</Keyword>
<RootNamespace>libproj</RootNamespace>
</PropertyGroup>
以下是我得到的输出（无属性）：
<?xml version="1.0" encoding="utf-8"?>
<Project>
<ItemGroup>
<ProjectConfiguration>
<Configuration>Debug</Configuration>
<Platform>Win32</Platform>
</ProjectConfiguration>
<ProjectConfiguration>
<Configuration>Release</Configuration>
<Platform>Win32</Platform>
</ProjectConfiguration>
</ItemGroup>
<PropertyGroup>
<ProjectGuid>{57900E99-A405-49F4-83B2-0254117D041B}</ProjectGuid>
<Keyword>Win32Proj</Keyword>
<RootNamespace>libproj</RootNamespace>
这是我目前的代码。我已经尝试了各种方法来编写属性。
string baseDir = (textBox2.Text + "\\" + safeFileName);
string vcName = Path.GetFileName(textBox1.Text);
string vcProj = Path.Combine(baseDir, vcName);
using (XmlReader reader = XmlReader.Create(textBox1.Text))
{
XmlWriterSettings settings = new XmlWriterSettings();
settings.OmitXmlDeclaration = true;
settings.ConformanceLevel = ConformanceLevel.Fragment;
settings.Indent = true;
settings.CloseOutput = false;
using (XmlWriter writer = XmlWriter.Create(vcProj, settings))
{
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element:
if (reader.Name == "ClInclude")
{
string include = reader.GetAttribute("Include");
string dirPath = Path.GetDirectoryName(textBox1.Text);
Directory.SetCurrentDirectory(dirPath);
string fullPath = Path.GetFullPath(include);
//string dirPath = Path.GetDirectoryName(fullPath);
copyFile(fullPath, 3);
string filename = Path.GetFileName(fullPath);
writer.WriteStartElement(reader.Name);
writer.WriteAttributeString("Include", "include/" + filename);
writer.WriteEndElement();
}
else if (reader.Name == "ClCompile" && reader.HasAttributes)
{
string include = reader.GetAttribute("Include");
string dirPath = Path.GetDirectoryName(textBox1.Text);
Directory.SetCurrentDirectory(dirPath);
string fullPath = Path.GetFullPath(include);
copyFile(fullPath, 2);
string filename = Path.GetFileName(fullPath);
writer.WriteStartElement(reader.Name);
writer.WriteAttributeString("Include", "src/" + filename);
writer.WriteEndElement();
}
else
{
writer.WriteStartElement(reader.Name);
}
break;
case XmlNodeType.Text:
writer.WriteString(reader.Value);
break;
case XmlNodeType.XmlDeclaration:
case XmlNodeType.ProcessingInstruction:
writer.WriteProcessingInstruction(reader.Name, reader.Value);
break;
case XmlNodeType.Comment:
writer.WriteComment(reader.Value);
break;
case XmlNodeType.Attribute:
writer.WriteAttributes(reader, true);
break;
case XmlNodeType.EntityReference:
writer.WriteEntityRef(reader.Value);
break;
case XmlNodeType.EndElement:
writer.WriteFullEndElement();
break;
}
}
}
}

在Soonts发表评论后，我最终看到了一些名称空间，并意识到为什么我的一次尝试无效。我必须事先指定命名空间，而不是允许编写器将其复制到读者XML文件中。以下是我解决问题的方法：
string baseDir = (textBox2.Text + "\\" + safeFileName);
string vcName = Path.GetFileName(textBox1.Text);
string vcProj = Path.Combine(baseDir, vcName);
using (XmlReader reader = XmlReader.Create(textBox1.Text))
{
XmlWriterSettings settings = new XmlWriterSettings();
//settings.OmitXmlDeclaration = true;
settings.ConformanceLevel = ConformanceLevel.Auto;
settings.Indent = true;
settings.CloseOutput = false;
string nameSpace = "http://schemas.microsoft.com/developer/msbuild/2003";
using (XmlWriter writer = XmlWriter.Create(vcProj, settings))
{
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element:
if (reader.Name == "ClInclude")
{
string include = reader.GetAttribute("Include");
string dirPath = Path.GetDirectoryName(textBox1.Text);
Directory.SetCurrentDirectory(dirPath);
string fullPath = Path.GetFullPath(include);
//string dirPath = Path.GetDirectoryName(fullPath);
//MessageBox.Show("Path: " + dirPath + Environment.NewLine + "Filename: " + filename);
copyFile(fullPath, 3);
string filename = Path.GetFileName(fullPath);
writer.WriteStartElement(reader.Name, nameSpace);
writer.WriteAttributeString("Include", "include/" + filename);
writer.WriteEndElement();
}
else if (reader.Name == "ClCompile" && reader.HasAttributes)
{
string include = reader.GetAttribute("Include");
string dirPath = Path.GetDirectoryName(textBox1.Text);
Directory.SetCurrentDirectory(dirPath);
string fullPath = Path.GetFullPath(include);
//string dirPath = Path.GetDirectoryName(fullPath);
//MessageBox.Show("Path: " + dirPath + Environment.NewLine + "Filename: " + filename);
copyFile(fullPath, 2);
string filename = Path.GetFileName(fullPath);
writer.WriteStartElement(reader.Name, nameSpace);
writer.WriteAttributeString("Include", "src/" + filename);
writer.WriteEndElement();
}
else
{
writer.WriteStartElement(reader.Name, nameSpace);
writer.WriteAttributes(reader, true);
}
break;
case XmlNodeType.Text:
writer.WriteString(reader.Value);
break;
case XmlNodeType.XmlDeclaration:
case XmlNodeType.ProcessingInstruction:
writer.WriteProcessingInstruction(reader.Name, reader.Value);
break;
case XmlNodeType.Comment:
writer.WriteComment(reader.Value);
break;
case XmlNodeType.Attribute:
writer.WriteAttributes(reader, true);
break;
case XmlNodeType.EntityReference:
writer.WriteEntityRef(reader.Value);
break;
case XmlNodeType.EndElement:
writer.WriteFullEndElement();
break;
}
}
}
