我正在尝试使用<catalog name="SPECIALS">节点并获取嵌套在其中的所有其他<catalog>个节点。我使用XMLTextReader来读取文件，是否有更好的方法？这是我目前使用的代码。
XmlTextReader reader = new XmlTextReader(filePath);
reader.ReadToFollowing("catalog");
do
{
Console.WriteLine("Name: {0}", reader.GetAttribute("name"));
}
while (reader.ReadToFollowing("catalog"));
答案 0 :(得分：3)
这正是XPath的用途。它非常有效，并且是一个w3c标准，用于启动：
XmlDocument doc = new XmlDocument( );
doc.Load( "TextFile1.xml" );
XmlNodeList specialCatalogs = doc.SelectNodes( "/mall_tree/catalog[@name='SPECIALS']/catalog" );
答案 1 :(得分：1)
这将为您提供后代＆＃34;目录＆＃34;节点：
XDocument xDoc = XDocument.Load("yourFile.xml");
var doc = xDoc.Descendants("catalog")
.Where(x => x.Attribute("name").Value == "SPECIALS")
.Select(x => x.Nodes())
.SelectMany(x => x.ToList())
.ToList();
对于Popular，Packs和Dime Store，输出为3 XNode个实例。
将它们打印到控制台：
foreach (var d in doc.OfType<XElement>())
Console.WriteLine("Name: {0}", d.Attribute("name").Value);
