Python example tutorial for building an XML tree structure

This article mainly introduced the Python constructs the XML tree structure the method, unifies the example form to analyze the Python creation and the print XML number structure implementation step and the related operation skill, needs the friend can refer to the next

The example in this article describes how Python constructs the XML tree structure. Share to everyone for your reference, as follows:

1. Building XML Elements

#encoding =utf-8from xml.etree Import elementtree as Etimport Sysroot=et. Element (' color ')  #用Element类构建标签root. text= (' black ')     #设置元素内容tree =et. ElementTree (Root)  #创建数对象, the parameter is the root node object Tree.write (sys.stdout)   #输出在标准输出中, can also be written in the file

Output Result:

<color>black</color>

2. Building a complete XML tree structure

#encoding =utf-8from xml.etree Import elementtree as Etimport Sysroot=et. Element (' goods ') name_con=[' YHB ', ' Lwy ']size_con=[' 175 ', ' the ']for I in range (2): #  Skirt=et. subelement (Root, ' skirt ') #  skirt.attrib[' index ']= ('%s '%i)  #具有属性的元素  Skirt=et. subelement (Root, ' skirt ', index= ('%s '%i)) #相当于上面两句  Name=et. subelement (skirt, ' name ') #子元素  name.text=name_con[i]       #节点内容  size=et. subelement (skirt, ' size ')  size.text=size_con[i]  tree=et. ElementTree (Root) et.dump (tree)  #打印树结构

Output Result:

<goods><skirt index= "0" ><name>yhb</name><size>175</size></skirt>< Skirt index= "1" ><name>lwy</name><size>170</size></skirt></goods>

Predefined character entities in the 3.XML specification

The so-called character entity is a special character in an XML document, such as "<" in the content of an element that cannot be entered directly because "<"
