问题描述
我一直在使用lxml创建rss feed的xml.但是我在标签上遇到了麻烦,无法真正弄清楚如何添加动态数量的元素.鉴于lxml似乎只是将函数作为函数的参数,因此我似乎无法弄清楚如何在不重新生成整个页面的情况下为动态数量的项目循环.
I have been using lxml to create the xml of rss feed. But I am having trouble with the tags and cant really figure out how to to add a dynamic number of elements. Given that lxml seems to just have functions as parameters of functions, I cant seem to figure out how to loop for a dynamic number of items without remaking the entire page.
rss = page = (
E.rss(
E.channel(
E.title("Page Title"),
E.link(""),
E.description(""),
E.item(
E.title("Hello!!!!!!!!!!!!!!!!!!!!! "),
E.link("htt://"),
E.description("this is a"),
),
)
)
)
推荐答案
channel = E.channel(E.title("Page Title"), E.link(""),E.description(""))
for (title, link, description) in container:
try:
mytitle = E.title(title)
mylink = E.link(link)
mydesc = E.description(description)
item = E.item(mytitle, mylink, mydesc)
except ValueError:
print repr(title)
print repr(link)
print repr(description)
raise
channel.append(item)
top = page = E.top(channel)
