</race>
所以每个种族都有
<race id="211911"
将其添加到称为提名的子元素中，作为种族标记，因此成为提名
<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"和其子代提名重复此操作。
您可以遍历所有race标签，获取id并将其添加到nomination：
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)
我建议您使用Beautiful Soup。在这样的任务上做得很好。
from bs4 import BeautifulSoup
soup = BeautifulSoup(YOUR_HTML_HERE, 'html.parser')
for race in soup.find_all('race'):
raceid = race['id']
# recursive=False because you said you only want direct children.
# omit recursive=False if you want all nomination tags within each race.
for nomination in race.find_all('nomination', recursive=False):
nomination['raceid'] = raceid
print(soup.prettify("latin-1"))
您已经完成。
