python - 如何将多个 XML 文件解析为多个 CSV 文件？

Question

我使用此代码解析了 XML 文件，该代码适用于单个 xml 输入到单个 csv 输出。我尝试使用 glob 处理多个输入以及多个 csv 输出，但我知道这是不正确的。

import glob
import xml.etree.ElementTree as et
import csv

for file in glob.glob('./*.xml'):
    with open(file) as f:
        tree = et.parse(f)
        nodes = tree.getroot()

        with open(f'{f[:-4]}edited.csv', 'w') as ff:
            cols = ['dateTime','x','y','z','motion','isMoving','stepCount','groupAreaId','commit']
            nodewriter = csv.writer(ff)
            nodewriter.writerow(cols)
            for node in nodes:
                values = [ node.attrib.get(kk, '') for kk in cols]
                nodewriter.writerow(values)

我应该如何更改以获得多个 csv 输出？

您的代码当前使用文件句柄来形成输出文件名。代替 f 使用 file 如下:

import glob
import xml.etree.ElementTree as et
import csv

for file in glob.glob('./*.xml'):
    with open(file) as f:
        tree = et.parse(f)
        nodes = tree.getroot()

        with open(f'{file[:-4]}edited.csv', 'w') as ff:
            cols = ['dateTime','x','y','z','motion','isMoving','stepCount','groupAreaId','commit']
            nodewriter = csv.writer(ff)
            nodewriter.writerow(cols)
            for node in nodes:
                values = [ node.attrib.get(kk, '') for kk in cols]
                nodewriter.writerow(values)
