难道仅仅是我吗？我发现的LINQ to XML来排序的繁琐，相比与XPath [英] Is it just me? I find LINQ to XML to be sort of cumbersome, compared to XPath

问题描述

我是一个C＃程序员，所以我没有得到参加VB利用凉爽的XML语法。

I am a C# programmer, so I don't get to take advantage of the cool XML syntax in VB.

Dim itemList1 = From item In rss.<rss>.<channel>.<item> _
                Where item.<description>.Value.Contains("LINQ") Or _
                      item.<title>.Value.Contains("LINQ")

使用C＃，我发现的XPath 更容易去思考，更容易code，更容易理解，不是执行多嵌套查询使用的LINQ to XML 。看看这个语法，它看起来像希腊宣誓：

Using C#, I find XPath to be easier to think about, easier to code, easier to understand, than performing a multi-nested select using LINQ to XML. Look at this syntax, it looks like Greek swearing:

var waypoints = from waypoint in gpxDoc.Descendants(gpx + "wpt") 
          select new 
          { 
            Latitude = waypoint.Attribute("lat").Value, 
            Longitude = waypoint.Attribute("lon").Value, 
            Elevation = waypoint.Element(gpx + "ele") != null ? 
                waypoint.Element(gpx + "ele").Value : null, 
            Name = waypoint.Element(gpx + "name") != null ? 
                waypoint.Element(gpx + "name").Value : null, 
            Dt = waypoint.Element(gpx + "cmt") != null ? 
                waypoint.Element(gpx + "cmt").Value : null 
          }; 

所有铸造，重语法的可能性NullPointerExceptions的。这一切都不发生使用XPath。

All the casting, the heavy syntax, the possibility for NullPointerExceptions. None of this happens with XPath.

我喜欢LINQ在一般情况下，我用它的对象集合和数据库，但我第一次去圆与查询XML使我马上回的XPath。

I like LINQ in general, and I use it on object collections and databases, but my first go-round with querying XML led me right back to XPath.

难道仅仅是我吗？

我缺少的东西？

修改：有人投票关闭此为不是一个真正的问题。但它的是的一个真正的问题，说清楚。现在的问题是：我误解 东西的LINQ to XML？的

EDIT: someone voted to close this as "not a real question". But it is a real question, stated clearly. The question is: Am I misunderstanding something with LINQ to XML?

推荐答案

使用你感觉最舒服的，只要它能够完成任务。我用这两种方法取决于我需要做的与XML。这听起来好像你有什么LINQ是好的，什么XPath是很好的一个良好的手感。

Use what you feel the most comfortable with, as long as it gets the job done. I use both methods depending on what I need to do to with XML. It sounds to me like you've got a good handle on what LINQ is good for and what XPath is good for.
