Example of how Python builds an XML tree structure

This article illustrates Python's method of constructing XML tree structure. To share for your reference, specific as follows:

1. Build XML elements

#encoding=utf-8
from xml.etree import ElementTree as ET
import sys
root=ET.Element('color')  # with Element Class build tag 
root.text=('black')     # Set element content 
tree=ET.ElementTree(root)  # Creates a number object with the root node object as the argument 
tree.write(sys.stdout)   # The output is in standard output and can be written to a file 

Output results:

<color>black</color>

2. Complete XML tree structure was constructed

#encoding=utf-8
from xml.etree import ElementTree as ET
import sys
root=ET.Element('goods')
name_con=['yhb','lwy']
size_con=['175','170']
for i in range(2):
#  skirt=ET.SubElement(root,'skirt')
#  skirt.attrib['index']=('%s' %i)  # An element with attributes 
  skirt=ET.SubElement(root,'skirt',index=('%s' %i)) # Equivalent to the above two sentences 
  name=ET.SubElement(skirt,'name') # Child elements 
  name.text=name_con[i]       # Node content 
  size=ET.SubElement(skirt,'size')
  size.text=size_con[i]
  tree=ET.ElementTree(root)
ET.dump(tree)  # Print tree structure 

Output results:

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

3. Character entities predetermined in the XML specification

Character entities are special characters in XML documents, such as" < "Cannot be entered directly because" < "

字符实体	符号
<	<
>	>
&	&
&apos;
"
