compare two xml files with xslt?

Question

I have 2 xml files. How can I compare both files are equal or not by using xslt? If not equal means where the changes havebeen occur in the second xml?

In XPath 2.0 you could simple use fn:deep-equal.

Following the same pattern in XSLT 1.0, this stylesheet:

    
    
        
            
                
            
        
        
            
                Documents are different
            
            
                Documents are deep equal
            
        
    
    
        
        
            
                
                    
                        false
                    
                
                
                    
                    
                        
                    
                
            
            false
        
    
    
        
        
            false
        
    

Output:

Documents are different
