Python parse XML file operation instance _python

This article illustrates the implementation of Python parsing XML file operations. Share to everyone for your reference. The specific methods are as follows:

The contents of the XML file are as follows:

<?xml version= "1.0"?> 
<!--simple XML document__chapter 8--> 
<book> 
  <title> 
    Sample XML thing 
  </title> 
  <author> 
    <name> 
      <first> 
        ma 
      </ first> 
      <last> 
        xiaoju 
      </last> 
    </name> 
    <affiliation> 
      Springs Widgets, Inc. 
    </affiliation> 
  </author> 
  <chapter number= "1" > 
    <title> 
    </title> 
    <para> 
      I widgets are greate. Should buy lots of them forom
