我是xml的新手，我不知道如何用python xml.etree处理它？我从https://docs.python.org/2/library/xml.etree.elementtree.html#parsing-xml读取的基本内容非常有用，但仍然难以打印出几何下的纬度和经度值 - ＆gt; location.i尝试了类似这样的内容

        with open('data.xml', 'w') as f:
            f.write(xmlURL.text)
        tree = ET.parse('data.xml')
        root = tree.getroot()
        lat = root.find(".//geometry/location")
        print(lat.text)

Answer 1

你几乎得到了它。将root.find(".//geometry/location")更改为root.find(".//geometry/location/lat")：

lat = root.find(".//geometry/location/lat")
print(lat.text)
>> 12.3067864

同样适用于lng：

lng = root.find(".//geometry/location/lng")
print(lng.text)
>> 78.7957856

如何使用xml.etree.Elementree读取xml标记之间的文本？如果xml很复杂
