下面的 GE kml 文件不会直接在 html 代码中进行元素颜色识别。如何将它们连同名称及其坐标与 python 扩展一起提取到 csv 文件中。
我已经获得了名称和坐标,但元素颜色却无法获得。无法提取这些信息吗?
我使用了我在这里得到的几个代码,但元素的颜色仍然是个谜。其中之一是:
from pykml import parser
from pykml.factory import nsmap
namespace = {"ns": nsmap[None]}
with open('test.kml') as f:
root = parser.parse(f).getroot()
pms = root.xpath(".//ns:Placemark[.//ns:LineString]", namespaces=namespace)
for pm in pms:
print(pm.name)
print(pm.LineString.coordinates)
预期结果是一个 csv 文件,其中包含以下字段:名称;坐标;颜色或具有相同字段的简单表格。
