我正在寫一個解析工具來幫助我清理一個大的VC++項目，然後再爲它製作.net綁定。誰能告訴我爲什麼我的XML編寫器不寫屬性？
我正在使用一個XML編寫器來讀取一個xml文件並將每個元素寫出到一個新文件中。如果找到具有特定名稱的元素，則它執行一些代碼並將輸出值寫入元素值。
到目前爲止，它幾乎工作，除了一件事：它不是複製屬性。誰能告訴我爲什麼會發生這種情況？
這裏是什麼是應該複製/修改（包括屬性）的樣本：
<?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>
這是我得到的輸出（無屬性）：
<?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>
這是我的代碼目前。我已經盡了各種方法來寫出屬性。
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;
}
}
}
}
我幾乎可以肯定你的問題是你的XML命名空間的無知和\或「ConformanceLevel.Fragment」 – Soonts
對不起，我忘了提，我加ConformanceLevel.Fragment後我收到一個錯誤，指出由於XML無效，我需要添加它。我在嘗試不同的選項時實際上已將其刪除，但創建複製品時我無意中再次添加了它。就輸出而言，它是無關緊要的。儘管請解釋爲什麼我在這件事上的無知是問題所在？ – user1632018
@Soonts你基本上是對的。我的問題是我對XML命名空間的無知，並且缺乏它。我也將我的一致性級別更改爲Auto。謝謝。 – user1632018
