This article describes the method of building XML tree structure in Python. Share it for your reference, as follows:
1. Build XML elements
#encoding=utf-8
from import ElementTree as ET
import sys
root=('color') #Build tags with Element class=('black') #Set element contenttree=(root) #Create a number object, the parameters are root node object() #Output is in standard output, or can be written in a file
Output result:
<color>black</color>
2. Build a complete XML tree structure
#encoding=utf-8
from import ElementTree as ET
import sys
root=('goods')
name_con=['yhb','lwy']
size_con=['175','170']
for i in range(2):
# skirt=(root,'skirt')
# ['index']=('%s' %i) #Element with attributes skirt=(root,'skirt',index=('%s' %i)) #Equivalent to the above two sentences name=(skirt,'name') #Sube Elements =name_con[i] #Node Content size=(skirt,'size')
=size_con[i]
tree=(root)
(tree) #Print tree structure
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 specification
The so-called character entity is a special character in an XML document. If there is "<" in the element content, you cannot enter it directly because "<"
| Character entity | symbol |
|---|---|
| < | < |
| > | > |
| & | & |
| ' | |
| " |
