在python中反序列化xml.data

Question

我有一个包含很多属性的 xml 文件。所有属性都有相同的名称

我确实有一个解决方案，但它需要将 id 添加到属性中，以便我可以选择我想要的解决方案。但这需要在 xml 文件中进行调整。至于我的研究论文，我无法更改 xml 文件。那么，有没有一个命令或一段代码可以让 python 知道，我只想要属性名称，其值为 Geometry？例如。

如果我打电话给酒店，我就会得到所有的信息。我不知道如何过滤这部分以获得我想要的部分。有什么建议吗？

我在 python 中添加了我的解决方案。但一定有一种方法无需对 xml 进行调整。

#parse 
mytree = ET.parse('C:/Users/f.badloe/.spyder-py3\Stagefiles/ASD_18_244_KW_0001_WM0230(BaseanlogROB).xml') # data van xml naar python

Answer 1

我找到了一个解决方案，无需在 xml 文件中进行调整。 通过这个命令我可以选择我需要的属性。

for prop in myroot.findall(".//shape[@Name= 'Waarde']//prop[@name ='RefPoint']"): RefPoint= print(prop.text)
