</race>
所以对于每个种族级别
<race id="211911"
将其作为 raceid 附加到名为 nomination 的子元素中，这样 nomination 就变成了
<nomination raceid="211911" number="1" saddlecloth="1" horse="Prized Icon" id="198206" idnumber=""
...
<nomination raceid="211911" number="4" saddlecloth="4" horse="Crown Him" id="202278" idnumber=""
然后为 <race id="211912" 重复此操作以及作为其子项的提名。
最佳答案
你可以遍历所有的 race 标签，获取 id 并将其添加到 nomination 中:
d = pq(html)
for race_el in d('race'):
race = pq(race_el)
race_id = race.attr('id')
# get the nominations and add the attribute
for nom_el in race.items('nomination'):
pq(nom_el).attr('raceid', race_id)
