导航栏名称及url爬取

不知道为啥这个js网页是curl不下来的，就将html节点复制了下来，然后用了如下代码爬取：

'''
//*[@id="catalog-undefined"]/span/a
/body/div[1]/div[5]/div/div/div[1]/div[2]/div[1]/div[1]/nav/div/div[2]/div/div/div/div[1]/div[3]/div[1]/div/div/div[8]/span[3]/span/div/span/span/a
/body/div[1]/div[5]/div/div/div[1]/div[2]/div[1]/div[1]/nav/div/div[2]/div/div/div/div[1]/div[3]/div[1]/div/div/div[11]/span[3]/span/div/span/span/a
/body/div[1]/div[5]/div/div/div[1]/div[2]/div[1]/div[1]/nav/div/div[2]/div/div/div/div[1]/div[3]/div[1]/div/div//span[3]/span/div/span/span/a
'''

xpath='/html/body/div[1]/div[5]/div/div/div[1]/div[2]/div[1]/div[1]/nav/div/div[2]/div/div/div/div[1]/div[3]/div[1]/div/div//span[3]/span/div/span/span/a'
file='yashu_body.html'
base='https://www.yuque.com'

from lxml import etree

html = etree.parse(file, etree.HTMLParser())
for e in html.xpath(xpath):
	print(e.attrib['title']+'\n'+base+e.attrib['href'])

不知道有没有更好的方式。
