C# Use Linq to Extract a individual XML mandatee for each XML file in a summary.
原标题:C# Use Linq to Extract a single XML attribute for each XML file in a directory

我如何利用Linq在名录中提取一个XML特性表,并将这一要素列入一个C#清单。 我是否必须逐个处理每件档案。 XML的档案相当庞大,所以我不想把整个档案装上记忆。

Thanks, j

问题回答

除非档案数量庞大(100兆米+) 我无法推翻该法典的成文:

var result = Directory.GetFiles(filePath)
    .Select(path => XDocument.Load(path))
    .Select(doc => doc.Root.Element("A").Attribute("B").Value)
    .ToList();

我确实希望您的XML文件不是“......>。

你们确实必须去过每一个档案,这至少意味着每个档案的XML内容足以符合要求。

XDocument (i.e. LINQ to >,将每起案件填上完整的文件,因此,你可以直接使用XmlReader。 这将需要做更多的工作:在你到达正确位置之前,你必须阅读XML的节点,并跟踪你所处的位置。
