Question

我有一个XML文档，我循环并将输出解析为控制台。所有工作等，但我需要能够确定标签从父节点关闭的位置。例如：

<activity date="2013-07-05T06:42:35" name="open" host="55.555.20.5554">
  <user id="EU-user@email.co.uk" name="J Bloggs" memberType="E" />
  <storageObject docId="4130-7447-0000" name="Documents name" size="1903885" fileExtension="pdf">
    <cabinet name="Client Cabinet">NG-XXXXXX</cabinet>
    <Matter>0000</Matter>
    <Client>X54654</Client>
    <Author>L Bloggs</Author>
  </storageObject>
</activity>

在每个活动结束时，我希望能够输出一行来确定每个活动结束的控制台输出。

有没有办法确定何时使用XDocument发生元素“close”标记？

Answer 1

您不需要确定标签关闭的位置。 XDocument将为您确定：

var activities = from a in xdoc.Descendants("activity")
                 let u = a.Element("user")
                 let so = a.Element("storageObject")
                 select new {
                     Date = (DateTime)a.Attribute("date"),
                     Name = (string)a.Attribute("name"),
                     User = new {
                          Id = (string)u.Attribute("id"),
                          Name = (string)u.Attribute("name")
                     },
                     Storage = new {
                          Client = (string)so.Element("Client")
                     }
                     //...
                 };

它会创建强类型对象，您可以迭代它们：

foreach(var activity in activities)
   Console.WriteLine("{0} on {1}", activity.Name, activity.Date);

Answer 2

怎么样：

// Load document into XDocument instance.
var doc = XDocument.Load("source.txt");

// query for all <activity> element.
var activities = doc.Root.Elements("activity");
// add XComment after each of them.
foreach (var a in activities)
{
    a.AddAfterSelf(new XComment("------------"));
}

// Print document into console.
Console.WriteLine(doc.ToString());

每后打印</activity>。

使用XDocument确定标记关闭
