循环浏览xml文件列表?

编写CSV文件的最简单方法是使用 Standard CSV 。 要编写CSV文件,只需打开文件并使用默认编写器即可:

import csv
from os import listdir, path
import xml.etree.ElementTree as ET

mypath = 'C:\myfolder'

files = [f for f in listdir(mypath) if f.endswith('.xml')]

for file in files:
    tree = ET.parse(file)
    root = tree.getroot()

ns = {namespaces}

def myfunction():
    if 'something' in root.tag:
        filename = path.splitext(file)[0]
        var1 = root.find('./element1', ns)
        var2 = root.find('./element2', ns)

        row = [
            var1.text,
            var2.text
            ]

        # Open the file and store the data
        with open('outfile.csv', 'a', newline='') as csvfile:
            csv_writer = csv.writer(csvfile, delimiter=' ', quotechar='|', quoting=csv.QUOTE_MINIMAL)
            csv_writer.writerow(row)

    return row   

请注意 csf.writer 接收列表作为参数。
