Use Python to generate an XML Method Instance. Use python to generate an xml instance.

This example describes how to generate XML using Python. We will share this with you for your reference. The details are as follows:

1. bookstore. py

# Encoding: UTF-8 ''' generates an XML from a blank file in the form of a DOM tree based on a given XML Schema. ''' From xml. dom. minidom import Documentdoc = Document () # create a DOM Document Object bookstore = doc. createElement ('bookstore') # create the root element bookstore. setAttribute ('xmlns: xsi', "http://www.w3.org/2001/XMLSchema-instance") # Set the namespace bookstore. setAttribute ('xsi: noNamespaceSchemaLocation ', 'bookstore. xsd ') # reference the local XML Schemadoc. appendChild (bookstore) ########### book: python processes XML Minidom ################# book = doc. createElement ('book') book. setAttribute ('genre', 'xml') bookstore. appendChild (book) title = doc. createElement ('title') title_text = doc. createTextNode ('python processes XML Minidom ') # Write the element content to the 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: django ####################### book1 = doc. createElement ('book') book1.setAttribute ('genre', 'web') bookstore. appendChild (book1) title1 = doc. createElement ('title') title_text1 = doc. createTextNode ('django of Python website Writing ') 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 ('lil') author_last_name_text1 = doc. createTextNode ('4') author1.appendChild (author_first_name1) author1.appendChild (author_last_name1) Principal (author_first_name_text1) Principal (principal) book1.appendChild (author1) price1 = doc. createElement ('price') price_text1 = doc. createTextNode ('40') price1.appendChild (price_text1) book1.appendChild (price1) ########## write the DOM object doc 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. Use the XML generated by Python minidom according to the preceding XML Schema

Bookstore. xml

<? Xml version = "1.0"?> <Bookstore xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi: noNamespaceSchemaLocation = "bookstore. xsd "> <book genre =" XML "> <title> Use Python to process XML Minidom </title> <author> <first-name> </first-name> <last -name> 3 </last-name> </author> <price> 28 </price> </book> <book genre = "Web"> <title> write a website using Python django </title> <author> <first-name> LI </first-name> <last-name> 4 </last-name> </author> <price> 40 </price> </book> </bookstore>
