Chinadaily双语新闻爬取

今天临时需要爬取一些双语资料

（尚未清洗）

需要充分利用

下边代码是想拿到Chinadaily网页中每篇双语新闻的链接，首先研究这些网页的网址和网页结构，包括翻页一般是首页网址加上_2，_3...等等。所以以下代码只是拿到链接。

    page = urllib.urlopen(url)
    html = page.readlines()

    return html

    reg = r'src="(.+?\.jpg)" pic_ext'
    imgre = re.compile(reg)
    imglist = re.findall(imgre,html)

    for imgurl in imglist:
        urllib.urlretrieve(imgurl,'%s.jpg' % x)
        x+=1

                os._exit(0)
            else:
                url = re.findall(r'\d\d\d\d\-\d\d/\d\d/content\_\d{4,}.htm',line)
                print("http://language.chinadaily.com.cn/" + url[0])
                bi_urls.append("http://language.chinadaily.com.cn/" + url[0])

                
if __name__ == '__main__':        
    n = 1
    # os.system('wget -r --spider http://language.chinadaily.com.cn/news_bilingual.html')
    # #geturl(getHtml("http://language.chinadaily.com.cn/news_bilingual.html"))
    # '''
    while n:
        if(n < 2):
            html = getHtml("http://language.chinadaily.com.cn/columnist/columnist.html")
            
        elif(n > 1):
            html = getHtml("http://language.chinadaily.com.cn/columnist/columnist.html_" + str(n) + ".html" )
        geturl(html)
        n = n + 1

执行python bi_news.py >url.txt 把想要的网址保存

url.txt内容：

下一步是简单爬取把url中每行链接的网页内容，且把新闻按照月份整理进入文件夹，文件名是每个新闻链接的后面八位数字
