我正在尝试解析 XML 文档。有问题的文档是一个 AppxManifest 文件。
示例文档如下所示:
<?xml version="1.0" encoding="utf-8"?>
<Package xmlns="http://schemas.microsoft.com/appx/2010/manifest" xmlns:build="http://schemas.microsoft.com/developer/appx/2012/build" IgnorableNamespaces="build">

我尝试像这样解析它:
var xml=new XmlDocument();
xml.Load(myfile);
var mgr=new XmlNamespaceManager(xml.NameTable);
mgr.AddNamespace("", "http://schemas.microsoft.com/appx/2010/manifest");
var nodes=xml.SelectNodes("Applications");
但是,在我执行此操作后,nodes
将永远不会包含任何内容。xml 文档已加载等。usingSelectNodes("//*")
按预期返回每个节点。我的问题是什么?
我还尝试了该 XPath 查询的许多变体,例如
/Package/Applications/Application
Applications/Application
Applications/*
不过,似乎没有任何东西可以检索单个节点。理想情况下,我希望节点包含所有Application
节点
