帮助构建日志分析实用程序？ [英] help in building a log analysis utility ?

问题描述

我有大日志文件，其中包含文本和xml数据。我想从中取出包含相同id元素（在下面的情况值1中）的xml数据并进一步处理它。你可以建议一些从文件中获取xml数据的方法吗？







例如文件





02182015发送请求

< soap：envelope xmlns：soap =http：// schemas。 xmlsoap.org/soap/envelope/\">

< soap：header>



< soap：body>

< id> 1







02182015回应

< soap：envelope xmlns：soap =http://schemas.xmlsoap.org/soap/envelope/>

< soap：header>



< soap：body>

< id> 1

解决方案

.NET FCL提供了解析XML的不同方法。这是我对它们的简短概述：

1. 使用 System.Xml.XmlDocument class 。它实现了DOM接口;如果文档的大小不是太大，这种方式是最简单和最好的。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx [ ^ ]。
2. 使用类 System.Xml.XmlTextReader ;这是最快的阅读方式，特别是你需要跳过一些数据。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx [ ^ ]。
3. 使用类 System.Xml.Linq.XDocument ;这是类似于 XmlDocument 的最合适的方式，支持LINQ to XML Programming。
   参见 http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx [ ^ ]，http://msdn.microsoft.com/en-us/library/bb387063.aspx [ ^ ]。

另外，特别是根据数据来源，您可能希望使用序列化而不是直接处理XML，例如SOAP序列化或数据合同。请从这里开始：

http://en.wikipedia.org/wiki/Serialization [ ^ ]，

https://msdn.microsoft.com/en-us/library/ms733127% 28v = vs.110％29.aspx [ ^ ]。

解决方案

.NET FCL offers different ways to parse XML. This is my short overview of them:

1. Use System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^].
2. Use the class System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^].
3. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^], http://msdn.microsoft.com/en-us/library/bb387063.aspx[^].

Also, depending, in particular, on origin of data, you may want to use serialization instead of dealing with XML directly, such as SOAP serialization or Data Contract. Please start here:
http://en.wikipedia.org/wiki/Serialization[^],
https://msdn.microsoft.com/en-us/library/7ay27kt9%28v=vs.110%29.aspx[^],
https://msdn.microsoft.com/en-us/library/90c86ass%28v=vs.110%29.aspx[^],
https://msdn.microsoft.com/en-us/library/ms733127%28v=vs.110%29.aspx[^].
