Question

我正在读取XML文件，并尝试从中提取数据。我需要具有所有与“描述”类型相关联的特定ID的“描述”的所有实例，然后需要“描述”的值或文本。

des_id =获取项目的所有描述ID

des_value =获取这些ID的所有值

des_ids字典=将des_id与字典中的des_value关联

描述字典=将商品编号与des_ids字典关联

当我要导出为.csv时，如果看起来是xml文件描述数据中的最后一个项目编号，则要遍历列表中的所有部分。我需要使用文件中每个项目编号的值的各个描述代码。

在我知道它弄乱了我的意图的地方显示一段代码。

for part in soup.find_all('Item'):


for x in part.find_all('PartNumber'):

    partNum = x.get_text()

    for description in part.find_all('Description'):
        des_id = description.get('DescriptionCode')  # key
        des_value = description.get_text()  # value

        des_ids[des_id] = des_value

        descriptions[partNum] = [des_ids]

非常感谢您的帮助！

Ouput是带有PartNum的3列csv | des_id | des_value

Answer 1

问题：我需要单独的描述代码，并带有文件中每个商品编号的值。

for part in soup.find_all('Item'):
    for x in part.find_all('PartNumber'):
        partNum = x.get_text()
        print("partNum{}".format(partNum))

        for description in part.find_all('Description'):
            des_id = description.get('DescriptionCode')  # key
            des_value = description.get_text()  # value

            csv_data = {'PartNumber': partNum, 'DescriptionCode': des_id, 'Description': des_value}
            print("\t{}".format(csv_data))

输出：

partNum2000207
    {'DescriptionCode': 'ASC', 'PartNumber': '2000207', 'Description': "Here's a sample ASC description for 2000207"}
    {'DescriptionCode': 'ASM', 'PartNumber': '2000207', 'Description': '2000207 sample ASM description'}
    {'DescriptionCode': 'DEF', 'PartNumber': '2000207', 'Description': '2000207 Product'}
... (omitted for brevity)    
partNum2000408
    {'DescriptionCode': 'ASC', 'PartNumber': '2000408', 'Description': "Here's a sample ASC description for 2000208"}
    {'DescriptionCode': 'ASM', 'PartNumber': '2000408', 'Description': '2000208 sample ASM description'}
    {'DescriptionCode': 'DEF', 'PartNumber': '2000408', 'Description': '2000208 Product'}
 ... (omitted for brevity)
