使用 python 将 XML 转换为 CSV

我有以下 XML 文件需要转换为 CSV 才能导入 Magento。在下面 <values> <Value AttributeID="attributes"></Value> 每种产品都有数百种不同的可能性。

我尝试通过命令行使用xml2csv 和xmlutils.xml2csv，但没有成功。任何帮助，将不胜感激。

我不熟悉“Magento”，但这个程序将您的 XML 文件转换为 CSV 文件。生成的 CSV 文件有一列用于 Name，每个 Value 一列。

from xml.etree import ElementTree as ET
import csv

tree = ET.parse('x.xml')
root = tree.getroot()

columns = ['Name'] + [
    value.attrib.get('AttributeID').encode('utf-8')
    for value in tree.findall('.//Product//Value')]

with open('x.csv', 'w') as ofile:
    ofile = csv.DictWriter(ofile, set(columns))
    ofile.writeheader()
    for product in tree.findall('.//Product'):
        d = {value.attrib.get('AttributeID').encode('utf-8'):
             (value.text or '').encode('utf-8')
             for value in product.findall('.//Values/Value')}
        d['Name'] = product.findtext('Name')
        ofile.writerow(d)
