Use python to generate xml

1. Bookstore. py
 

 #  Encoding: UTF-8  
  '''  
Based on a given XML schema, an XML is generated from a blank file in the form of a DOM tree.
  ''' 
 From XML. Dom. minidom Import Document

Doc = Document () #  Create a DOM Document Object  
 
Bookstore = Doc. createelement ('  Bookstore  ' ) #  Create root element  
 Bookstore. setattribute ( '  Xmlns: xsi  ' , "  Http://www.w3.org/2001/XMLSchema-instance  " ) #  Set namespace  
 Bookstore. setattribute ('  Xsi: nonamespaceschemalocation  ' , '  Bookstore. XSD  ' ) #  Reference local XML Schema  
 Doc. appendchild (bookstore)

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  = "Book"  Type  = "Booktype"  /> 
 </ XSD: Sequence  > 
 </  XSD: complextype  > 

 <  XSD: complextype  Name  = "Booktype"  > 
 <  XSD: Sequence  >

3. Use the XML generated by Python minidom according to the preceding XML Schema
 

 
Bookstore. xml
 

 <?  XML version = "1.0"  ?>
