beautifulsoup找到特定标签

Question

我开始进入美丽的世界，但我遇到了一个我似乎无法解决的问题。

我this

网站，想解析项的值。此值可以在

<span class="gw2money-fragment">%value <i class="gw2money-silver">s</i></span> 

标签和

<span class="gw2money-fragment">%value <i class="gw2money-copper">c</i></span>. 

获取这些值不是一个问题之间找到，问题是检查值是否是<i class="gw2money-silver">或<i class="gw2money-copper">标签内。

r = requests.get("http://www.gw2spidy.com/item/24467", proxies=proxyDict) 

soup = BeautifulSoup(r.text) 
checksoup = soup.find_all("span") 

numliste = [] 
for links in checksoup: 
    #print(links) 
    price = links.contents[0] 
    print(price)  

del numliste[0] 
print(numliste) 

这是我如何检索当前的铜和银值。

我搜索gw2money-fragment类，然后进行测试，看看这个类是包含i元素是什么：

for row in soup.find_all('tr'): 
    fragments = row.find_all('span', class_='gw2money-fragment') 
    if not fragments: 
     continue 
    label = row.th or row.td 
    print(label.text) 
    for fragment in fragments: 
     value = fragment.text.split()[0] 
     type_ = fragment.i['class'][0].rsplit('-', 1)[-1] 
     print('-', value, type_) 

演示：

>>> for row in soup.find_all('tr'): 
...  fragments = row.find_all('span', class_='gw2money-fragment') 
...  if not fragments: 
...   continue 
...  label = row.th or row.td 
...  print(label.text) 
...  for fragment in fragments: 
...   value = fragment.text.split()[0] 
...   type_ = fragment.i['class'][0].rsplit('-', 1)[-1] 
...   print('-', value, type_) 
...
