使用 Python 解析 XML 属性

Question

I am trying to parse out all the green highlighted attributes (some sensitive things have been blacked out), I have a bunch of XML files all with similar formats, I already know how to loop through all of them individually them I am having trouble parsing out the specific attributes though.

XML Document

I need the text in the attributes: name="text1"

from

project logLevel="verbose" version="2.0" mainModule="Main" name="text1">

destinationDir="/text2" from

put label="Put Files" destinationDir="/Trigger/FPDMMT_INBOUND">

destDir="/text3" from

copy disabled="false" version="1.0" label="Archive Files" destDir="/text3" suffix="">

I am using

import csv
import os
import re
import xml.etree.ElementTree as ET

tree = ET.parse(XMLfile_path)
item = tree.getroot()[0]
root = tree.getroot()
print (item.get("name"))
print (root.get("name"))

This outputs:

Main
text1

The item.get pulls the line at index [0] which is the first line root in the tree which is <module The root.get pulls from the first line <project

I know there's a way to search for exactly the right part of the root/tree with something like:

test = root.find('./project/module/ftp/put')
print (test.get("destinationDir"))

I need to be able to jump directly to the thing I need and output the attributes I need.

Any help would be appreciated

Thanks.

Simplified copy of your XML:

xml = '''<project logLevel="verbose" version="2.0" mainModule="Main" name="hidden">
    <module name="Main">
        <createWorkspace version="1.0"/>
        <ftp version="1.0" label="FTP connection to PRD">
            <put label="Put Files" destinationDir="destination1">
            </put>
        </ftp>
        <ftp version="1.0" label="FTP connection to PRD">
            <put label="Put Files" destinationDir="destination2">
            </put>
        </ftp>
        <copy disabled="false" destDir="destination3">
        </copy>
    </module>
</project>
'''

# solution using ETree
from xml.etree import ElementTree as ET

root = ET.fromstring(xml)

name = root.get('name')
ftp_destination_dir1 = root.findall('./module/ftp/put')[0].get('destinationDir')
ftp_destination_dir2 = root.findall('./module/ftp/put')[1].get('destinationDir')
copy_destination_dir = root.find('./module/copy').get('destDir')

print(name)
print(ftp_destination_dir1)
print(ftp_destination_dir2)
print(copy_destination_dir)

# solution using lxml
from lxml import etree as et

root = et.fromstring(xml)

name = root.get('name')
ftp_destination_dirs = root.xpath('./module/ftp/put/@destinationDir')
copy_destination_dir = root.xpath('./module/copy/@destDir')[0]

print(name)
print(ftp_destination_dirs[0])
print(ftp_destination_dirs[1])
print(copy_destination_dir)
