PythonでDOM(Document Object Model)を使ってXMLファイルからデータを読み込む例です。この例ではJava, C++, Pythonのそれぞれのprint関数をリストアップします。

This is example code for reading XML by DOM(Document Object Model) in Python. In this example, it list up print function in Java, C++ and Python for each rule.

Reading XML in Python is very easy!

sample.xml


<?xml version="1.0" encoding="UTF-8"?>




<CommandList>
  <cmd type="Java">System.out.print("test")</cmd>
  <cmd type="C++">printf("test")</cmd>
  <cmd type="Python">print("test")</cmd>
</CommandList>

source code.


from xml.dom.minidom import parse



def printCommandList(xmlPath):
  dom = parse(xmlPath);
  root = dom.documentElement
  print(root.nodeName);
    
  cmdNodeList = root.childNodes;
  for cmdNode in cmdNodeList:
    if cmdNode.nodeName == "cmd":
      typeName = cmdNode.getAttributeNode("type");
      command = "";
      cmdText = cmdNode.childNodes[0];
      if cmdText.nodeType == cmdText.TEXT_NODE:
        command = cmdText.data;
      print(str(typeName.nodeValue)+":"+str(command));
       
  dom.unlink();




printCommandList("./sample.xml");
