解析Visual Studio项目文件的XML [英] Parsing Visual Studio Project File as XML

问题描述

使用动态xml解析器，我试图加载一个VS项目文件作为XElement。这是项目文件的缩小版本：

 <？xml version =1.0encoding =utf-8 > 
< Project ToolsVersion =4.0DefaultTargets =Buildxmlns =http://schemas.microsoft.com/developer/msbuild/2003> 
< ItemGroup> 
< / ItemGroup> 
< ItemGroup> 
< / ItemGroup> 
< / Project> 
  

文件似乎加载，当我ToString（），我得到的内容。但是，当试图选择元素时，什么也找不到：

  XElement元素; 
 
 public DynamicXmlParser（string fileName）
 {
 element = XElement.Load（fileName）; 
} 
 
 public override bool TryGetMember（GetMemberBinder binder，out object result）
 {
 result = null; 
 if（element == null）return false; 
 
 XElement子元素= element.Element（binder.Name）; 
 
 if（subElement == null）return false; 
 
 result = new DynamicXmlParser（subElement）; 
 return true; 
} 
  

subElement总是空的。

binder.Name 是 ItemGroup

  dynamic xmlDoc = new DynamicXmlParser（SampleFileName）; 
 Debug.Pring（xmlDoc.ItemGroup.ToString（））;但是，当我从项目节点中删除所有属性时，subElement将按预期成为一个ItemGroup XElement。 
 
 
 
为什么当属性在项目节点中时可以返回任何元素？
解决方案
您可能要求在空命名空间中的元素，为什么实际上这些元素存在于xmlns =http://schemas.microsoft.com/developer/msbuild/2003中。查看XNamespace。
 
 
 
例如尝试：
  XNamespace msbuildNs =http://schemas.microsoft.com/developer/msbuild/2003
 XElement subElement = element.Element（msbuildNs + binder.Name）; 
  
 
Using a dynamic xml parser, I'm trying to load a VS Project file as an XElement. Here is a slimmed down version of the project file:
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <ItemGroup>
    </ItemGroup>
    <ItemGroup>
    </ItemGroup>
</Project>
The file appears to load in the sense that when I ToString(), I get the contents. However, when trying to pick out elements, nothing is ever found:
XElement element;

public DynamicXmlParser( string fileName )
{
    element = XElement.Load( fileName );
}

public override bool TryGetMember( GetMemberBinder binder, out object result )
{
    result = null;
    if ( element == null ) return false;

    XElement subElement = element.Element( binder.Name );

    if ( subElement == null ) return false;

    result = new DynamicXmlParser( subElement );
    return true;
}
subElement is always null.

binder.Name is ItemGroup
dynamic xmlDoc = new DynamicXmlParser( SampleFileName );
Debug.Pring(xmlDoc.ItemGroup.ToString());
However, when I remove all attributes from the Project node, subElement becomes an ItemGroup XElement as expected.

Why can I return any elements when the attributes are in the project node?
解决方案
You are probably asking for elements in empty namespace why in fact the elements live in  xmlns="http://schemas.microsoft.com/developer/msbuild/2003". Take a look at XNamespace.

For instance try:
XNamespace msbuildNs = "http://schemas.microsoft.com/developer/msbuild/2003"
XElement subElement = element.Element(msbuildNs + binder.Name);
