我需要使用BeautifulSoup将单词列表转换为跨度。
例如
<html><body>word-one word-two word-one</body></html>
需要
<html><body><span>word-one</span> word-two <span>word-one</span></body></html>
需要将word-one移动到跨度中的位置
到目前为止，我能够使用以下方法找到这些元素：
for html_element in soup(text=re.compile('word-one')):
print(html_element)
此类文本替换为跨度尚不清楚。
我做过这样的事情，其中变量html是你的代码<html><body>word-one word-two word-one</body></html>，我将文本和代码分开，然后将它们加在一起。
soup = BeautifulSoup(html,'html.parser')
text = soup.text # Only the text from the soup
soup.body.clear() #Clear the text between the body tags
new_text = text.split() # Split beacuse of the spaces much easier
for i in new_text:
new_tag = soup.new_tag('span') #Create a new tag
new_tag.append(i) #Append i to it (from the list that's split between spaces)
#example new_tag('a') when we append 'word' to it it will look like <a>word</a>
soup.body.append(new_tag) #Append the whole tag e.g. <span>one-word</span)
我们也可以使用正则表达式来匹配一些单词。
soup = BeautifulSoup(html, 'html.parser')
text = soup.text # Only the text from the soup
soup.body.clear() # Clear the text between the body tags
theword = re.search(r'w+', text) # Match any word in text
begining, end = theword.start(), theword.end()
soup.body.append(text[:begining]) # We add the text before the match
new_tag = soup.new_tag('span') # Create a new tag
new_tag.append(text[begining:end])
# We add the word that we matched in between the new tag
soup.body.append(new_tag) # We append the whole text including the tag
soup.body.append(text[end:]) # Append everything that's left
我相信我们可以以类似的方式使用.insert。
