我想iframe从网页上获取所有内容.
码:
site = "http://" + url
f = urllib2.urlopen(site)
web_content = f.read()
soup = BeautifulSoup(web_content)
info = {}
content = []
for iframe in soup.find_all('iframe'):
info['src'] = iframe.get('src')
info['height'] = iframe.get('height')
info['width'] = iframe.get('width')
content.append(info)
print(info)
pprint(content)
结果print(info):
{'src': u'abc.com', 'width': u'0', 'height': u'0'}
{'src': u'xyz.com', 'width': u'0', 'height': u'0'}
{'src': u'http://www.detik.com', 'width': u'1000', 'height': u'600'}
结果pprint(content):
[{'height': u'600', 'src': u'http://www.detik.com', 'width': u'1000'},
{'height': u'600', 'src': u'http://www.detik.com', 'width': u'1000'},
{'height': u'600', 'src': u'http://www.detik.com', …我有两张桌子.1st table => member {member_id,name,active} 2nd table => savings {savings_id,member_id,month,year,amount,type,paid}

PS：我无法将所有图像导出到资源，因为我的图像文件夹包含很多子文件夹
什么是这个SQL查询的linq查询
SELECT
sum(IIF(jenis = 'primer',1,0)) as sum_primer,
sum(IIF(jenis = 'sekunder',1,0)) as sum_sekunder
FROM cooperations
尝试从101 Linq Samples中搜索相同的示例,但没有得到任何线索
更新 所以,我在我的C#中使用此查询
var query = (from c in db_cooperations.cooperations
group c by c.jenis into g
select
(new
{
sum_primer = g.Count(c => c.jenis == "primer"),
sum_sekunder = g.Count(c => c.jenis == "sekunder")
})).ToArray();
输出是
sum_primer sum_sekunder

0 0
那么,我如何删除零值,然后返回一行
