我使用feedparser模块成功地解析了来自国家飓风中心的 RSS 提要：

import feedparser
feedparser.parse('https://www.nhc.noaa.gov/gis-at.xml') #Works Fine
feedparser.parse('https://www.nhc.noaa.gov/gis-ep.xml') #Works Fine

但是，当我尝试从中太平洋飓风中心读取表面上相似的提要时，我生成了一个 KeyError：

feedparser.parse('http://www.prh.noaa.gov/cphc/gis-cp.xml') #Doesn't work

这是 feedparser 的错误吗？CPHC 的 Feed 格式是否错误？有没有我忘记指定的选项？问题似乎在于没有一个名为“where”的键，但我不知道为什么这对 NHC 提要来说不是问题。堆栈复制如下：

>>>  import feedparser
>>>  feedparser.parse('http://www.prh.noaa.gov/cphc/gis-cp.xml')
