大家好最近想試著撰寫網頁爬蟲想抓取網頁的這部分資訊 http://imgur.com/rNdE4hh

嘗試的結果為 # -*- coding: utf-8 -*- from urllib2 import urlopen import xml.etree.ElementTree as ET from lxml import etree import mechanize import sys url = "http://www.tham.com.tw/recipe6.php" path = "//*[@id=\"left-inner\"]/div[2]/div[3]" html = urlopen(url).read() tree = etree.HTML(html) startindex = 4 data = tree.xpath(path) print data[0].text Output: >>> ================================ RESTART ================================ >>> 材料 2人份 >>> 看網頁的原始碼猜測是因為<br />阻擋了判斷的緣故請問這個有解嗎?? -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 123.195.222.114 ※ 文章網址: https://www.ptt.cc/bbs/Python/M.1457968017.A.79E.html
