推荐答案

我们不做你的功课你 - 它将帮助你学习。我怎么知道这是作业？因为每年的这个时候我们都会有大量新成员提出这个问题。



首先 - 参考你的课程作业。如果您不知道如何开始这项任务，那么您需要与您的导师讨论。



其次 - 学习如何研究。这种能力可能是你可以从教育中获得的最重要的事情 - 如何找到你需要的信息。

We don't do your homework for you - it is set to help you learn. How do I know this is homework? Because this time of year we get a flood of new members asking this question.

First - refer to your course work. If you can't any idea of how to start this assignment then you need to discuss this with your tutor.

Secondly - learn how to research. This ability is probably the most important thing you can pick up from education - how to find the information you need.

首先，请阅读我对这个问题的评论。好像，您必须编写自定义方法来拆分 [ ^ ] 公司名称和产品名称来自 pname 节点。



实现这一目标的方法很少。您可以使用：

XDocument类（System.Xml.Linq） [ ^ ]

XmlDocument Class（System.Xml） [ ^ ]

或 XML序列化 [ ^ ]

来操作xml数据。



对于小部分数据，您可以使用Linq，请参阅：。 NET语言 - XML数据集成查询 [ ^ ]

LINQ - C＃中的示例查询，Visual Studio 2010的VB.NET [ ^ ]

在任何其他情况下，我建议使用序列化和反序列化。

First of all, please read my comment to the question. Seems, you have to write custom method to split[^] company name and product name from pname node.

There's few ways to achieve that. You can use:
XDocument Class (System.Xml.Linq)[^]
XmlDocument Class (System.Xml)[^]
or XML Serialization[^]
to manipulate xml data.

For small portion of data, you can use Linq, see: .NET Language-Integrated Query for XML Data[^]
LINQ - Sample Queries in C#, VB.NET for Visual Studio 2010[^]
In any other case, i'd suggest to use serialization and deserialization.
