该代码用于搜索xml页面，并提取用户键入其商品名称的订单的商品id和客户id。

import xml.etree.ElementTree as ET

def search_product_in_xml(xml_file, product_name):
    tree = ET.parse(xml_file)
    root = tree.getroot()

    # 假设XML结构如下：
    # <orders>
    #     <order>
    #         <customer_id>...</customer_id>
    #         <product>
    #             <product_id>...</product_id>
    #             <name>...</name>
    #         </product>
    #     </order>
    #     ...
    # </orders>

    results = []
    for order in root.findall('order'):
        product = order.find('product')
        if product is not None and product.find('name').text == product_name:
            customer_id = order.find('customer_id').text
            product_id = product.find('product_id').text
            results.append((customer_id, product_id))

    return results

# 使用示例
xml_file_path = 'path_to_your_xml_file.xml'
product_name_to_search = '商品名称'
results = search_product_in_xml(xml_file_path, product_name_to_search)

for customer_id, product_id in results:
    print(f'Customer ID: {customer_id}, Product ID: {product_id}')
