你会如何​​比较两个XML文档？ [英] How would you compare two XML Documents?

问题描述

至于一些广泛的单元测试的基类的一部分，我写一个辅助函数，递归比较1 XmlDocument对象的节点到另一个在C＃（.NET）。这方面的一些要求：

As part of the base class for some extensive unit testing, I am writing a helper function which recursively compares the nodes of one XmlDocument object to another in C# (.NET). Some requirements of this:

• 在第一份文件是在源，例如：我想要的XML文档的样子。因此，第二就是我想要找的差异，它不能包含的额外的节点不是第一个文件
• 在被发现太多显著差异时必须抛出一个异常，它应该由一个人扫了一眼描述很容易理解。
• 子元素顺序很重要，属性可以以任意顺序。
• 在有些属性是忽略不计;特别是 XSI：的schemaLocation 和的xmlns：XSI ，不过我想应该能够传递哪些是
• prefixes命名空间必须在两个属性和元素相匹配。
• 元素之间的空白是无关紧要的。
• 元素的或者的子元素的或的的InnerText ，但不能同时使用。

• The first document is the source, e.g. what I want the XML document to look like. Thus the second is the one I want to find differences in and it must not contain extra nodes not in the first document.
• Must throw an exception when too many significant differences are found, and it should be easily understood by a human glancing at the description.
• Child element order is important, attributes can be in any order.
• Some attributes are ignorable; specifically xsi:schemaLocation and xmlns:xsi, though I would like to be able to pass in which ones are.
• Prefixes for namespaces must match in both attributes and elements.
• Whitespace between elements is irrelevant.
• Elements will either have child elements or InnerText, but not both.

而我再杀共同的东西：有没有人写过这样code和它有可能要在这里分享

While I'm scrapping something together: has anyone written such code and would it be possible to share it here?

在顺便说一句，你会称之为第一和第二文档？我已经提到他们作为源和目标，但感觉错了，因为在源是我想在目标的样子，否则我扔一个例外。

On an aside, what would you call the first and second documents? I've been referring to them as "source" and "target", but it feels wrong since the source is what I want the target to look like, else I throw an exception.
