C# 如何获取此元素的xpath?
我需要返回dependentAssembly的codebase属性(即asmv1:assembly=>dependency=>dependentAssembly(第一个)=>codebase属性) 以下是XML文件:C# 如何获取此元素的xpath?,c#,xml,xpath,C#,Xml,Xpath,我需要返回dependentAssembly的codebase属性(即asmv1:assembly=>dependency=>dependentAssembly(第一个)=>codebase属性) 以下是XML文件: <?xml version="1.0" encoding="utf-8"?> <asmv1:assembly xsi:schemaLocation="urn:schemas-microsoft-com:asm.v1 assembly.adaptive.xsd" m

这是可行的,但它非常丑陋:
var childNode = node.ChildNodes
.OfType<XmlElement>()
.First(n => n.LocalName == "dependency")
.ChildNodes[0]
.Attributes["codebase"].InnerText;
var childNode=node.ChildNodes
第()类
.First(n=>n.LocalName==“依赖关系”)
.ChildNodes[0]
.Attributes[“codebase”].InnerText;
依赖项
继承默认命名空间,URI为urn:schemas microsoft com:asm.v2
:
var nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("asmv1", "urn:schemas-microsoft-com:asm.v1");
nsmgr.AddNamespace("asmv2", "urn:schemas-microsoft-com:asm.v2");
var node = xmlDoc.DocumentElement.SelectSingleNode(@"/asmv1:assembly/asmv2:dependency", nsmgr);
您是否尝试过
asmv1:assembly/asmv1:dependency
?这可能不起作用,但你永远不知道。@G0dsquad不起作用,谢谢!作为参考,最后的xpath是/asmv1:assembly/asmv2:dependency/asmv2:dependentAssembly[1]/@codebase
var nsmgr = new XmlNamespaceManager(xmlDoc.NameTable);
nsmgr.AddNamespace("asmv1", "urn:schemas-microsoft-com:asm.v1");
nsmgr.AddNamespace("asmv2", "urn:schemas-microsoft-com:asm.v2");
var node = xmlDoc.DocumentElement.SelectSingleNode(@"/asmv1:assembly/asmv2:dependency", nsmgr);
