Reading XML documents from Python

For beginners who have just been familiar with Python, they will gradually find that this programming language is actually a computer programming language with powerful functions and simple application. We will introduce in detail how to read XML documents from Python today.

Recently, I made a small function, which contains the function of reading XML documents from Python. It encapsulates a reading class, including reading all the data in xml and returning the list set; reads the value of this node and Its subnode based on the unique node value.

 
 

  
  
From xml. dom. minidom import parse, parseString
  
  
Class XmlConfig:
  
  
Def _ init _ (self, path ):
  
  
Selfself. xmlData = self. GetXml (path)
  
  
Def GetText (self, nodelist ):
  
  
R = ""
  
  
For nxd in nd. childNodes:
  
  
Rr = r + nxd. nodeValue
  
  
Return r
  
  
# Retrieve all xml data
  
  
Def GetXml (self, path ):
  
  
Doc1 = parse (path)
  
  
St = doc1.firstChild
  
  
Websites = st. childNodes
  
  
LstList = []
  
  
For sw in websites:
  
  
If sw. nodeType = sw. ELEMENT_NODE:
  
  
Lsty = []
  
  
For nd in sw. childNodes:
  
  
If nd. nodeType = nd. ELEMENT_NODE:
  
  
NdndName = nd. nodeName
  
  
NdndValue = nd. firstChild. data
  
  
B = (ndName, ndValue)
  
  
Lsty. append (B)
  
  
LstList. append (lsty)
  
  
Return lstList
  
  
# Obtain the values of a single node and Its subnodes
  
  
Def GetSingle (self, siteName ):
  
  
For item in self. xmlData:
  
  
For k, v in item:
  
  
If v = siteName:
  
  
Return item
  
  
# Obtain the values of a single node and Its subnodes
  
  
Def GetSingleDict (self, siteName ):
  
  
Lst = self. GetSingle (siteName)
  
  
Dic1 = {}
  
  
If len (lst)> 0:
  
  
For item in lst:
  
  
Dic1 [item [0] = item [1]
  
  
Return dic1
 
 

Xml document

 
 

  
  
< ?xml version="1.0" encoding="UTF-8"?> 
  
  
< Site> 
  
  
< WebSites> 
  
  
< website>http://www.xxx.net< /website> 
  
  
< loginurl>http:///www.xxx.net/login.php< /loginurl> 
  
  
< username>uname=xxx< /username> 
  
  
< passwd>pass=123456< /passwd> 
  
  
< other>< ![CDATA[r=5&remember=0&ur=xxx]]>< /other> 
  
  
< config>WebSite.ini< /config> 
  
  
< configname>XXX< /configname> 
  
  
< /WebSites> 
  
  
< WebSites> 
  
  
< website>http://www.xxx.com< /website> 
  
  
< loginurl>http:///www.xxx.com/login.php< /loginurl> 
  
  
< username>uname=xxx< /username> 
  
  
< passwd>pass=123456< /passwd> 
  
  
< other>< ![CDATA[r=5&remember=0&ur=xxx]]>< /other> 
  
  
< config>WebSite.ini< /config> 
  
  
< configname>XXX< /configname> 
  
  
< /WebSites> 
  
  
< /Site> 
 
 

Python calls to read XML documents:

 
 

  
  
if __name__=="__main__":  
  
  
f=XmlConfig()  
  
  
print f.xmlData 
 
 

The above is an introduction to reading XML documents from Python.
