OpenCv Haar函数创建的XML内部是什么。

Question

I am using OpenCV haartraining to create a classifier for an object. http://note.sonots.com/SciSoftware/haartraining.html
The classifier creates a XML file. I wanna know what means all those values from the XML file.
I have an idea for a start up and is all about optimizing the process of detecting an object based on multiple xml from training data. Can anyone explain me what is actually inside a XML. Lets say if i have 10 xml files from 10 training different date but with the same subject( the same car let's say) is there anything that is common between the file?

You have a couple of options here:

• Open a XML generated by OpenCV, take a look inside and see if you can make sense of it;
• Download OpenCV source code and see how the XML is created in the code;
• Download OpenCV Reference Manual v2.1 and investigate page 470.
