这是我的XML响应 -

我希望能够获得 ALL “Map”属性的名称,即time,isobaric,lat,lon。目前使用以下代码,仅打印出第一个。我尝试迭代但它只打印时间变量n次。
import requests
from xml.etree import ElementTree
response = requests.get("http://rda.ucar.edu/thredds/dodsC/aggregations/g/ds083.2/2/TP.ddx?Temperature_isobaric")
tree = ElementTree.fromstring(response.content)
grid = tree.find("{http://xml.opendap.org/ns/DAP2}Grid")
map = grid.find("{http://xml.opendap.org/ns/DAP2}Map")
for child in map:
print(child.get('name'))
答案 0 :(得分:2)
两个小变化:
map = grid.findall("{http://xml.opendap.org/ns/DAP2}Map")
for child in map:
print(child.get('name'))
findall
获取所有匹配项,当您循环child in map
时,您希望确保返回与child
相关的值。
