解析Visual Studio项目文件的XML

本文介绍了解析Visual Studio项目文件的XML的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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 =schemas.microsoft/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 =schemas.microsoft/developer/msbuild/2003中。查看XNamespace。

例如尝试：

XNamespace msbuildNs =schemas.microsoft/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="schemas.microsoft/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="schemas.microsoft/developer/msbuild/2003". Take a look at XNamespace.

For instance try:

XNamespace msbuildNs = "schemas.microsoft/developer/msbuild/2003" XElement subElement = element.Element(msbuildNs + binder.Name);
