本文实例讲述了使用Python生成XML的方法。分享给大家供大家参考,具体如下:
1. bookstore.py
#encoding:utf-8 ''' 根据一个给定的XML Schema,使用DOM树的形式从空白文件生成一个XML。 ''' from xml.dom.minidom import Document doc = Document() #创建DOM文档对象 bookstore = doc.createElement('bookstore') #创建根元素 bookstore.setAttribute('xmlns:xsi',"http://www.w3.org/2001/XMLSchema-instance")#设置命名空间 bookstore.setAttribute('xsi:noNamespaceSchemaLocation','bookstore.xsd')#引用本地XML Schema doc.appendChild(bookstore) ############book:Python处理XML之Minidom################ book = doc.createElement('book') book.setAttribute('genre','XML') bookstore.appendChild(book) title = doc.createElement('title') title_text = doc.createTextNode('Python处理XML之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('张') author_last_name_text = doc.createTextNode('三') 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写网站之Django#################### book1 = doc.createElement('book') book1.setAttribute('genre','Web') bookstore.appendChild(book1) title1 = doc.createElement('title') title_text1 = doc.createTextNode('Python写网站之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('李') author_last_name_text1 = doc.createTextNode('四') 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) ########### 将DOM对象doc写入文件 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. 根据上面的XML Schema用Python minidom生成的XML
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处理XML之Minidom </title> <author> <first-name> 张 </first-name> <last-name> 三 </last-name> </author> <price> 28 </price> </book> <book genre="Web"> <title> Python写网站之Django </title> <author> <first-name> 李 </first-name> <last-name> 四 </last-name> </author> <price> 40 </price> </book> </bookstore>
