Python：获取XML条数据，放入多值字典

Question

我在 XML 中有一些数据需要存储在字典中。 XML文件如下：

<market>
   <grocery>
      <items>
         <item>
            <name>Apple</name>
            <seller>AppleSeller</seller>
            <quantity>30</quantity>
            <price>10</price>
         </item>
         <item>
            <name>Orange</name>
            <seller>OrangeGuy</seller>
            <quantity>25</quantity>
            <price>20</price>
         </item>
         <item>
            <name>Banana</name>
            <seller>BananaMan</seller>
            <quantity>35</quantity>
            <price>5</price>
         </item>
         <item>
            <name>Apple</name>
            <seller>AppleSeller</seller>
            <quantity>67</quantity>
            <price>20</price>
         </item>
      </items>
   </grocery>

   <cleaning>
      <items>
         <item>
            <name>Disinfectant</name>
            <seller>MrClean</seller>
            <quantity>24</quantity>
            <price>50</price>
         </item>
         <item>
            <name>Mop</name>
            <seller>MopIndustries</seller>
            <quantity>5</quantity>
            <price>30</price>
         </item>
      </items>
   </cleaning>

</market>

所以我需要获取数据并根据 Python3 脚本中的第一个 child（杂货、清洁等）对其进行排序需要使用XML ElementTree.

最终的字典（或其他东西）应该通过保留唯一名称（Apple、Orange、Banana 等）来存储数据，如下所示：

sorted_dictionary = {
"grocery": ["Apple", "AppleSeller", "30", "10"],
"grocery": ["Orange", "OrangeGuy", "25", "20"],
"grocery": ["Banana", "BananaMan", "35", "5"],
"cleaning": ... (same as how grocery does it)
"cleaning": ...
}

Answer 1

您不能为字典中的所有元素创建相同的键。检查下面的代码，它将创建所有杂货的列表。

你可以对其他元素做同样的事情

import xml.etree.ElementTree as ET
root = ET.fromstring(xmlstring)
names = [i.text for i in root.findall('grocery/items/item/name')]
seller = [i.text for i in root.findall('grocery/items/item/seller')]
quantity = [i.text for i in root.findall('grocery/items/item/quantity')]
price = [i.text for i in root.findall('grocery/items/item/price')]
ls = [list(i) for i in zip(names,seller,quantity,price)]
print(ls)
d = {"grocery": ls}
print(d)
