blocks|key|2239564|text|你有没有考虑过使用XPath？这似乎是获取所有子节点的一种简单方法。然后，您将能够遍历节点并比较属性/textContent。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2239565|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Have you looked at using XPath at all? Seems like an easy way to grab all of the child nodes. Then you'd be able to loop through the nodes and compare the attributes/textContent.

I was looking for something to compare two XML like you, and I found this solution that works very well.

This might be a very alternative solution for you but this is how I would do it. 

First, I'd try to get the format into something much more manageable like an array so I would convert the XML to an array.

<a href="http://www.bytemycode.com/snippets/snippet/445/" rel="nofollow">http://www.bytemycode.com/snippets/snippet/445/</a> 

This is some simple code to do just that. 

Then PHP has an array_diff() function that can show you the differences.

<a href="http://www.php.net/manual/en/function.array-diff.php" rel="nofollow">http://www.php.net/manual/en/function.array-diff.php</a>

This may or may not work for you considering what you need to do with the differences but if you're looking to just identify and act upon them this might be a very quick solution to your problem.

Try the xmldiff extension

<a href="http://pecl.php.net/xmldiff" rel="nofollow">http://pecl.php.net/xmldiff</a>

It's based on the same library as the perl module DifferenceMarkup, you'll get a diff XML document and can even merge then.

I want to compare 2 big xml files and retrieve the differences. Like ExamXML and DiffDog do. The solution I found was cycling through all child nodes of each file simultaneously and check if they are equal. But I have no idea how to achieve that... How can I loop through all child nodes and their properties? How can I check if the first element of the first file is equal to the first element of the second file, the second element of the first file is equal to the second element of the second file and so on?

Do yo have a better idea to compare 2 xml files?

我想要比较两个大的xml文件，并检索差异。就像ExamXML和DiffDog一样。我找到的解决方案是同时遍历每个文件的所有子节点，并检查它们是否相等。但我不知道如何做到这一点……如何遍历所有子节点及其属性？如何检查第一个文件的第一个元素是否等于第二个文件的第一个元素，第一个文件的第二个元素是否等于第二个文件的第二个元素，以此类推？你有没有更好的办法来比较两个xml文件？
