XPath和*的.csproj [英] XPath and *.csproj

问题描述

我肯定在这里缺少一些重要的细节。我不能让与Visual Studio项目文件。NET的XPath的工作。

I am for sure missing some important detail here. I just cannot make .NET's XPath work with Visual Studio project files.

让我们加载XML文档：

Let's load an xml document:

var doc = new XmlDocument();
doc.Load("blah/blah.csproj");

现在执行我的查询：

var nodes = doc.SelectNodes("//ItemGroup");
Console.WriteLine(nodes.Count); // whoops, zero

当然，也有文件中命名的ItemGroup节点。此外，该查询的工作：

Of course, there are nodes named ItemGroup in the file. Moreover, this query works:

var nodes = doc.SelectNodes("//*/@Include");
Console.WriteLine(nodes.Count); // found some

与其他文档，XPath的工作就好了。
我绝对疑惑了。任何人都可以解释我是怎么回事？

With other documents, XPath works just fine. I am absolutely puzzled about that. Could anyone explain me what is going on?

推荐答案

您可能需要添加到该命名空间的引用 http://schemas.microsoft.com/developer/msbuild/2003 。

You probably need to add a reference to the namespace http://schemas.microsoft.com/developer/msbuild/2003.

我有一个类似的问题，我写了一篇关于它的here.做这样的事情：

I had a similar problem, I wrote about it here. Do something like this:

XmlDocument xdDoc = new XmlDocument();
xdDoc.Load("blah/blah.csproj");

XmlNamespaceManager xnManager =
 new XmlNamespaceManager(xdDoc.NameTable);
xnManager.AddNamespace("tu",
 "http://schemas.microsoft.com/developer/msbuild/2003");

XmlNode xnRoot = xdDoc.DocumentElement;
XmlNodeList xnlPages = xnRoot.SelectNodes("//tu:ItemGroup", xnManager);

这篇关于XPath和*的.csproj的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
