如何使用Python和ElementTree从XML文件的所有元素中提取所有内容？

Question

I have the following XML file called Artists.xml, which contains information on several artists as shown bellow:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Artists>
<Singer name="Britney">
    <Albums>7</Albums>
    <Country>USA</County>
    <Last Single>  Piece of Me
      <Year>2011</Year>
   </Last Single>
</Singer>
<Singer name="Justin">
    <Albums>8</Albums>
    <Country>USA</County>
    <Last Single> Rock Your Body
      <Year>2004</Year>
   </Last Single>
</Singer>
</Artsts>

I am using the Python library ElementTree in order to extract the content of all tags. So far this is the Python code I have written:

from xml.etree import cElementTree as ET
tree = ET.parse('Artists.xml')
root = tree.getroot()
for child in root:
    for content in child:
       print(child[content].text)

Despite that, when I run the script I see no inputs in my console. I would like to see something like : 7 USA Piece of Me 2011, 8 USA Rock Your Body 2004. Could someone help me understand what I am doing wrong? Thanks in advance!

Answer 1

using xml.etree.ElementTree

test.xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Artists>
    <Singer name="Britney">
        <Albums>7</Albums>
        <Country>USA</Country>
        <LastSingle>
               Piece of Me
              <Year>2011</Year>
       </LastSingle>
    </Singer>
    <Singer name="Justin">
        <Albums>8</Albums>
        <Country>USA</Country>
        <LastSingle> Rock Your Body
          <Year>2004</Year>
       </LastSingle>
    </Singer>
</Artists>

Hence :

from xml.etree import ElementTree
tree = ElementTree.parse('test.xml')
root = tree.getroot()
results = root.findall('Singer')

for elem in results:
    for e in elem:
        print(e.text.strip())

OUTPUT :

7
USA
Piece of Me
8
USA
Rock Your Body

Answer 2

A generic approach. Convert the XML to dict and print the dict. (The file 55726013.xml contains your sample data). As you can see the code has zero knowledge about the XML structure.

import xmltodict
import json

with open('55726013.xml') as fd:
    doc = xmltodict.parse(fd.read())

print(json.dumps(doc, indent=4))

Output

{
    "Artists": {
        "Singer": [
            {
                "@name": "Britney", 
                "Albums": "7", 
                "Country": "USA", 
                "LastSingle": {
                    "Year": "2011", 
                    "#text": "Piece of Me"
                }
            }, 
            {
                "@name": "Justin", 
                "Albums": "8", 
                "Country": "USA", 
                "LastSingle": {
                    "Year": "2004", 
                    "#text": "Rock Your Body"
                }
            }
        ]
    }
}
