Question

这是我的代码输出

<h1 class="it-ttl" id="itemTitle" itemprop="name"><span class="g-hdn">Details about   </span>item name goes here</h1>

我想只获取项目名称，而不是“有关”部分的详细信息。

我的Python代码选择了某个div id

for content in soup.select('#itemTitle'):
    print(content.text)

Answer 1

您可以使用decompose() clear()或extract()。根据文件：

Tag.decompose（）从树中删除标签，然后完全销毁它及其内容

Tag.clear（）删除标记的内容

PageElement.extract（）从树中删除标记或字符串。它返回提取的标记或字符串

from bs4 import BeautifulSoup
html = '''<h1 class="it-ttl" id="itemTitle" itemprop="name"><span class="g-hdn">Details about   </span>item name goes here</h1>'''

soup = BeautifulSoup(html, 'lxml')
for content in soup.select('#itemTitle'):
    content.span.decompose()
    print(content.text)

输出：

  item name goes here

Answer 2

我的答案受到accepted answer的启发。

代码：

from bs4 import BeautifulSoup, NavigableString

data = '''
<h1 class="it-ttl" id="itemTitle" itemprop="name"><span class="g-hdn">Details about   </span>item name goes here</h1>
'''

soup = BeautifulSoup(data, 'html.parser')
inner_text = [element for element in soup.h1 if isinstance(element, NavigableString)]
print(inner_text)

输出：

['item name goes here']

Answer 3

这个怎么样：

from bs4 import BeautifulSoup
html= """<h1 class="it-ttl" id="itemTitle" itemprop="name"><span class="g-hdn">Details about   </span>item name goes here</h1>"""

soup = BeautifulSoup(html, "lxml")

text = soup.find('h1', attrs={"id":"itemTitle"}).text
span = soup.find('span', attrs={"class":"g-hdn"}).text

final_text = text[len(span):]

print(final_text)

这导致：

item name goes here

Answer 4

尝试这是否有效

from bs4 import BeautifulSoup 
soup = BeautifulSoup("""<h1 class="it-ttl" id="itemTitle" itemprop="name">
<span class="g-hdn">Details about  </span>
item name goes here</h1>""")  
print(soup.find('h1', {'class': 'it-ttl'}).contents[-1].strip())
