Python读取大型xml文件并保存为csv文件

import xml.etree.ElementTree as ET
import csv

def parse_xml(xml_file):
    tree = ET.parse(xml_file)
    root = tree.getroot()

    data = []
    for child in root:
        # 提取所需的数据，可以根据XML文件的结构进行相应的处理
        # 示例中假设XML文件的结构为<item><name>...</name><price>...</price></item>
        name = child.find('name').text
        price = child.find('price').text

        # 将提取的数据保存到列表中
        data.append([name, price])

    return data

def save_to_csv(data, csv_file):
    with open(csv_file, 'w', newline='') as file:
        writer = csv.writer(file)
        writer.writerow(['Name', 'Price'])  # 写入CSV文件的表头
        writer.writerows(data)  # 写入数据行

if __name__ == '__main__':
    xml_file = 'large.xml'  # 替换为你的XML文件路径
    csv_file = 'output.csv'  # 替换为你想保存的CSV文件路径

    data = parse_xml(xml_file)
    save_to_csv(data, csv_file)
