如何使用lambda表達式從XML文件中檢索屬性的值？

Question

例如我Let'say想BRANCHNAME的價值

<repo> 
    <Changeset value="abcdefg"/> 
    <BranchName value="gamma"/> 
    <BuildNumber value="1.2.3.4"/> 
</repo> 

類我正在尋找的：

var doc = XDocument.Load(repoPath); 
var c = doc.Descendants("repo")..... Where(x=> x.Name == "changeset"); 

Answer 1

using System.Xml; 
using System.Xml.Linq; 
... 
var c = doc.Descendants("repo") 
      .Elements("Changeset") // getting "Changeset" nodes 
      .Select(x => x.Attribute("value")) // getting "value" attribute 
      .Where(a => a != null) // skip nulls (just in case) 
      .Select(a => a.Value) // getting "value" attribute value 
      .ToList();
