- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
如何为简单的 Web 抓取应用程序解析表格中的表格?
我的流程是:
HTML代码:
<table border="0" cellpadding="2" cellspacing="1" width="660">
<tbody><tr bgcolor="#CCCCCC">

<th class="IntWxHeader">Weather</th>
<th class="IntWxHeader">Temperature</th>

我想抓取最后一行的所有数据(
这是我目前所拥有的:
try:
resp = urlopen(url)
except URLError as e:
print "An error occured fetching %s \n %s" % (url, e.reason)
return 1
soup = BeautifulSoup(resp.read(), 'lxml')
# get outer table
try:
outerTables = soup.findAll('table')
except AttributeError as e:
print "No tables found, exciting"
return 1
# get inner table
try:
for table in outerTables:
innerTables = soup.findAll('table')
except AttributeError as e:
print "No inner tables found"
return 1
# get rows
try:
for table in innerTables:
rows = soup.findAll('tr')
except AttributeError as e:
print "No rows found"
return 1
# get headers
headers = []
try:
for row in rows:
markup = soup.findAll('th')
except AttributeError as e:
print "No headers found"
return 1
for i in range(0,len(markup)):
headers.append(markup[i].string)
我走的路对吗?
最佳答案
你的 html 有一个表,标题是 th 标签,一些行是 tr 标签,行内是你想要在 td 标签:
h = """<table border="0" cellpadding="2" cellspacing="1" width="660">
<tr bgcolor="#CCCCCC">
<th class="IntWxHeader">Time</th>
<th class="IntWxHeader">Weather</th>
<th class="IntWxHeader">Temperature</th>
<th class="IntWxHeader">Dewpoint</th>
<th class="IntWxHeader">Humidity</th>
<th class="IntWxHeader">Pressure</th>
<th class="IntWxHeader">Winds</th>
<th class="IntWxHeader">Visibility</th>
