Question

我开始进入beautifulsoup，但我遇到了一个我似乎无法解决的问题。

我有this

网站并希望解析该项的价值。该值可以在

之间找到

<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>.

获取这些值不是问题，问题是检查值是否在<i class="gw2money-silver">或<i class="gw2money-copper">标记内。

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)

这就是我目前检索铜和银的价值。

Answer 1

我会搜索gw2money-fragment类，然后测试以查看包含在i元素中的类：

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_)
