XML 使用具有多个键值的相同标签来字典 Python
XML to dict Python with same tags that have multiple keys values
针对 XML Dict 提出了很多解决方案，但我无法解决我的特定用例。
我的XML格式是有多个相同的标签，但每个标签内可能有很多键值，而且并非所有标签都有一致数量的键值。这使它具有挑战性。

指标：
箭头 - “edgeStyle=orthogonalEdgeStyle”
对象（服务）-“resIcon=service_2”/service_1 等
到目前为止我做了什么 -
使用 xml.etree.ElementTree 我在循环中提取标签和属性，使用我想要的关键字提取这些值。'
结果存储在数组中。
id = []
attrb = []
objects_found = []
arrows_found = []
最后我想转换成dict对象-
{
id: '1',
attrb: 'service'
object: 'service_a'
arrows: true
arrow_start: {coordinate}
arrow_end: {coordinate}
}
如果没有箭头：
{
id: '1',
attrb: 'service'
object: 'service_a'
}
我的代码：
for item in tree.iter():
if item.tag == 'mxCell':
id = item.attrib['id']
# to split the long list of words with ';' in 'style' key. Major info is in there.
style_list = item.attrib['style'].split(';')
for style in style_list:
if '=' in style:
style_key = style.split('=')[0]
style_value = style.split('=')[1]
if style_key == 'shape' and style_value != 'icon' and 'keyword-a' in style_value:
service_icon = style_value
id.append(id)
attrb.append("service_name")
objects_found.append(service_icon)
elif style_key == 'resIcon':
service_icon = style_value
id.append(id)
attrb.append("service_name")
objects_found.append(service_icon)
elif style_key == 'edgeStyle':
arrow_style = style_value
id.append(id)
attrb.append("arrows")
arrows_found.append(arrow_style)
我试过
- 字典(zip))。但挑战在于可能有一些可选键在某些 ID 中不存在。
- pandas 数据框（并不理想，因为我打算听写）但我尝试使用 csv 获取 table 形式，数组也无法正常工作，因为我得到的数组值已经丢失ids和key-values之间的关系通过将它们放入数组中来识别，并且不同长度的数组不能一起放入数据帧中。
对任何解决方案有什么好的建议吗？
终于找到简单易行的方法
根据当前的逻辑，我可以使用关键字提取数据，并且对于每个已识别的键值，我将追加到嵌套字典中。
即
dictObj = {} 并在 for 循环中，开始为每个 id 在其中启动嵌套字典 - dictObj[id] = {}
确定每个键后，继续 dictObj[id].update({'key': value})
不确定这是否是最有效的方法，但至少我得到了我想要的输出。如果有人有更好的方法，请分享。
