The example in this article shows how to generate XML using Python. I will share it with you for your reference as follows:

1. bookstore.py 


#encoding:utf-8
'''
 According to the 1 A given XML Schema , the use of DOM The tree form is generated from a blank file 1 a XML . 
'''
from xml.dom.minidom import Document
doc = Document() # create DOM The document object 
bookstore = doc.createElement('bookstore') # Creating the root element 
bookstore.setAttribute('xmlns:xsi',"http://www.w3.org/2001/XMLSchema-instance")# Set the namespace 
bookstore.setAttribute('xsi:noNamespaceSchemaLocation','bookstore.xsd')# Refer to the local XML Schema
doc.appendChild(bookstore)
############book:Python To deal with XML the Minidom################
book = doc.createElement('book')
book.setAttribute('genre','XML')
bookstore.appendChild(book)
title = doc.createElement('title')
title_text = doc.createTextNode('Python To deal with XML the Minidom') # Element content write 
title.appendChild(title_text)
book.appendChild(title)
author = doc.createElement('author')
book.appendChild(author)
author_first_name = doc.createElement('first-name')
author_last_name = doc.createElement('last-name')
author_first_name_text = doc.createTextNode(' zhang ')
author_last_name_text = doc.createTextNode('3')
author.appendChild(author_first_name)
author.appendChild(author_last_name)
author_first_name.appendChild(author_first_name_text)
author_last_name.appendChild(author_last_name_text)
book.appendChild(author)
price = doc.createElement('price')
price_text = doc.createTextNode('28')
price.appendChild(price_text)
book.appendChild(price)
############book1:Python Write the site Django####################
book1 = doc.createElement('book')
book1.setAttribute('genre','Web')
bookstore.appendChild(book1)
title1 = doc.createElement('title')
title_text1 = doc.createTextNode('Python Write the site Django')
title1.appendChild(title_text1)
book1.appendChild(title1)
author1 = doc.createElement('author')
book.appendChild(author1)
author_first_name1 = doc.createElement('first-name')
author_last_name1 = doc.createElement('last-name')
author_first_name_text1 = doc.createTextNode(' li ')
author_last_name_text1 = doc.createTextNode('4')
author1.appendChild(author_first_name1)
author1.appendChild(author_last_name1)
author_first_name1.appendChild(author_first_name_text1)
author_last_name1.appendChild(author_last_name_text1)
book1.appendChild(author1)
price1 = doc.createElement('price')
price_text1 = doc.createTextNode('40')
price1.appendChild(price_text1)
book1.appendChild(price1)
###########  will DOM object doc Written to the file 
f = open('bookstore.xml','w')
f.write(doc.toprettyxml(indent = ''))
f.close()

2. bookstore.xsd 


<?xml version="1.0" encoding="utf-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
 <xsd:element name="bookstore" type="bookstoreType"/>
 <xsd:complexType name="bookstoreType">
  <xsd:sequence maxOccurs="unbounded">
   <xsd:element name="book" type="bookType"/>
  </xsd:sequence>
 </xsd:complexType>
 <xsd:complexType name="bookType">
  <xsd:sequence>
   <xsd:element name="title" type="xsd:string"/>
   <xsd:element name="author" type="authorName"/>
   <xsd:element name="price" type="xsd:decimal"/>
  </xsd:sequence>
  <xsd:attribute name="genre" type="xsd:string"/>
 </xsd:complexType>
 <xsd:complexType name="authorName">
  <xsd:sequence>
   <xsd:element name="first-name" type="xsd:string"/>
   <xsd:element name="last-name" type="xsd:string"/>
  </xsd:sequence>
 </xsd:complexType>
</xsd:schema>

3. XML is generated from Python minidom according to XML Schema above

bookstore.xml 


<?xml version="1.0" ?>
<bookstore xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="bookstore.xsd">
 <book genre="XML">
  <title>
   Python To deal with XML the Minidom
  </title>
  <author>
   <first-name>
     zhang 
   </first-name>
   <last-name>
    3
   </last-name>
  </author>
  <price>
   28
  </price>
 </book>
 <book genre="Web">
  <title>
   Python Write the site Django
  </title>
  <author>
   <first-name>
     li 
   </first-name>
   <last-name>
    4
   </last-name>
  </author>
  <price>
   40
  </price>
 </book>
</bookstore>
