Python method for generating XML files

This article mainly describes the use of Python to generate XML methods, combined with specific examples of detailed analysis of Python generated XML file specific fluency and related considerations, the need for friends can refer to the following

The example in this article describes how to generate XML using Python. Share to everyone for your reference, 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 () #创建DOM文档对象bookstore = doc.createelement (' bookstore ') # Create root element Bookstore.setattribute (' Xmlns:xsi ', "Http://www.w3.org/2001/XMLSchema-instance") # Set the namespace Bookstore.setattribute (' xsi:nonamespaceschemalocation ', ' bookstore.xsd ') #引用本地XML schemadoc.appendchild ( Bookstore) ########### #book:P ython processing xml minidom############### #book = doc.createelement (' book ') Book.setattribute ( ' Genre ', ' XML ') bookstore.appendchild (book) title = Doc.createelement (' title ') Title_text = Doc.createtextnode (' Python handles XML minidom ') #元素内容写入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 (' three ') 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 (' + ') price.appendchild (Price_text) Book.appendchild (Price) ########### #book1:P Ython Write the django################### of the website #book1 = doc.createelement (' book ') Book1.setattribute (' genre ', ' Web ') bookstore.appendchild (book1) title1 = doc.createelement (' title ') Title_text1 = Doc.createtextnode (' python writes website 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 (' Lee ') author_last_name_text1 = Doc.createtextnode (' four ') 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 (' + ') price1.appendchild (PRICE_TEXT1) Book1.appendchild (Price1) ########### writes DOM object doc to 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 generated from Python minidom based on the 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 processing XML minidom  </title>  <author>   <first-name>    Zhang   </first-name>   <last-name >    three   </last-name>  </author>  <price>  </book </price> > <book genre= "Web" >  <title>   python writing web site Django  </title>  <author>   <first-name>    Lee   </first-name>   <last-name>    four   </last-name>  </author>  <price>  </price> </book></bookstore>
