你能帮我提供一些python的解决方案吗，谢谢大家阅读这篇文章。你可以将xml读入参数并发送到PostgreSQL，如下所示：
root = etree.parse("XML/epg.xml")
for i in root.findall("item"):
p = [i.find(n).text for n in ("program", "start", "duration")]
# now you get list with values of parameters
postgres = ('INSERT INTO epg_live (program, start, duration) VALUES (%s, %s, %s)', p)
cursor.execute(parser,postgres)
cursor.commit()
不知道从何处获取
