在Python3中解析循环中的XML数据以创建多个对象

python xml python-3.x

在Python3中解析循环中的XML数据以创建多个对象,python,xml,python-3.x,Python,Xml,Python 3.x,我有以下XML结构： <celestialBodies> <stars> <star> <item name="Name">Sun</item> <item name="Distance from the Earth">100000</item> <item name="Size">9</item> <item

但是正如您所看到的，我不想自己硬编码planets，而是希望以一种好的方式从XML文件中获取数据。因此，与其说“水星”，不如说它应该穿过这棵树，将每个天体的值输入到变量中，然后创建对象

我无法理解的是XML阅读部分。无论我尝试了什么，我都无法循环通过级别将值读入变量。我已经尝试过BeautifulSoup、lxml和ET，但没有成功

一些试验：

   root = lxml.etree.fromstring('planet_info.xml')
   results = root.findall('planets')
   textnumbers = [r.find('planet/name').text for r in results]
   print(textnumbers)

或

每次都会产生错误。应该有一个简单的方法来做到这一点

有什么建议吗

编辑：因此，通过以下内容，我可以联系到这两个孩子，但仅此而已：

   # Get the data from the XML
   solarSystem = ET.parse('planet_info.xml')
   celestialBodies = solarSystem.getroot()
   for bodies in celestialBodies:
       print(bodies.tag, bodies.attrib)

输出：

stars {}
planets {}

如何在这些文件中循环并检索值？

这段代码使用etree很有效。缺少一行，该行仅返回

项

元素，这些元素的

名称

设置为某个值

import xml.etree.ElementTree as ET

root = ET.parse(PATH_TO_YOUR_FILE)
planets = root.findall('./planets/planet')

planets_list = []
for planet in planets:
        name = planet.find("./item[@name='Name']").text
        d = planet.find("./item[@name='Distance from the Earth']").text
        //...
        planets_list.append(Planet(name, d, ...)

从这里你应该可以自己解决剩下的问题。希望对您有所帮助。

首先，您可以找到行星和恒星元素，将它们添加到列表中并从中选择第一个值

import xml.etree.ElementTree as ET  
dump = ET.parse('planet_info.xml') 
root = dump.getroot()  
planet_name = star_name = planet_list = []  
for content in root:
    planet_name = content.findall("planet")
    star_name = content.findall("star")
    if planet_name:
        for planet in planet_name:
             planet_list.append(Planet(planet[0].text, planet[1].text, etc)
    elif star_name:
        for star in star_name:
            planet_list.append(Planet(star[0].text, star[1].text, etc)
    else:
        print("Nothing")

这里有一个简单的方法来迭代该数据结构。为了保持代码的自包含性，我直接从字符串而不是从文件中读取XML
