[英]How do I get only the part of an HTML tree which is above a certain tag with certain string BeautifulSoup?
[英]How do I get an item but only if is a sibiling of a certain tag
我有一個很長的 html 但這是一個片段:
<tr>
<td data-bind="text:name, css: isActive() ? 'variable-active': 'variable-inactive'" class="variable-active">Vehicle</td>
<td data-bind="text:value">Ford</td>
</tr>
<tr>
<td data-bind="text:name, css: isActive() ? 'variable-active': 'variable-inactive'" class="variable-inactive">Model</td>
<td data-bind="text:value">Focus</td>
</tr>
我想根據它是否為“變量活動”來獲取所有內容標簽,然后從下一個“td”標簽中獲取值。 在這種情況下,由於第二個 class 標記是“變量無效”,因此 output 應該是:
"Vehicle - Ford"
我設法根據“變量活動”獲取第一個標簽,但我無法從其他標簽中獲取第二個值。 這是我的代碼:
from bs4 import BeautifulSoup
with open ("html.html","r") as f:
doc = BeautifulSoup(f,"html.parser")
tag = doc.findAll("tr")[0]
print(tag.findAll(class_="variable-active")[0].contents[0]) #vehicle
tag.findNextSibling(class_="variable-active") # nothing
您想構建您的搜索有點不同:
tag = soup.findAll("tr")[0]
tag1 = tag.find(class_="variable-active") # <-- use .find
tag2 = tag1.findNextSibling() # <-- use tag1.findNextSibling() to find next sibling tag
print(tag1.text) # <-- use .text to get all text from tag
print(tag2.text)
印刷:
Vehicle
Ford
另一個使用 CSS 選擇器的版本:
data = soup.select(".variable-active, .variable-active + *")
print(" - ".join(d.text for d in data))
印刷:
Vehicle - Ford
