我正在尝试仅从已选中的表单中检索复选框旁边的标签文本。
这是 html:
<div class="x-panel-bwrap" id="ext-gen1956"><div
class="x-panel-body" id="ext-gen1957" style="width: 226px;">
<div class="x-form-check-wrap" id="ext-gen1959"><input type="checkbox" autocomplete="off" id="ext-comp-1609" name="ext-comp-1609" class=" x-form-checkbox x-form-field">
<label for="ext-comp-1609" class="x-form-cb-label" id="ext-gen1960">labeltext1</label></div>
<div class="x-form-check-wrap" id="ext-gen1961"><input type="checkbox" autocomplete="off" id="ext-comp-1607" name="ext-comp-1607" class=" x-form-checkbox x-form-field">
<label for="ext-comp-1607" class="x-form-cb-label" id="ext-gen1962">labeltext2</label></div>
<div class="x-form-check-wrap" id="ext-gen1963"><input type="checkbox" autocomplete="off" id="ext-comp-1605" name="ext-comp-1605" class=" x-form-checkbox x-form-field" checked="">
<label for="ext-comp-1605" class="x-form-cb-label" id="ext-gen1964">labeltext3</label></div>
我想要获取的复选框旁边的标签由属性 checked=""区分
for checkboxes in soup.find_all('input', attrs={"id":"ext-comp-1609"}):
if checkboxes.find('input', attrs={"checked":""}):
label_1 = soup.find('label',{'id':'ext-gen1960'}).text
print(label_1)
else:
continue
for checkboxes in soup.find_all('input', attrs={"id":"ext-comp-1607"}):
if checkboxes.find('input', attrs={"checked":""}):
label_2 = soup.find('label',{'id':'ext-gen1962'}).text
print(label_2)
except:
continue
for checkboxes in soup.find_all('input', attrs={"id":"ext-comp-1605"}):
if checkboxes.find('input', attrs={"checked":""}):
label_3 = soup.find('label',{'id':'ext-gen1964'}).text
print(label_3)
else:
continue
我的问题是,无论标签是否被选中,它都会抓取标签。我也尝试过使用 has_attr() 但它产生了相同的结果。
尝试过的解决方案:
soup = BeautifulSoup(browser.page_source, 'html.parser')
for checkbox in soup.find_all('input', checked=True):
print(checkbox.label.get_text())
和
soup = BeautifulSoup(browser.page_source, 'html.parser')
for checkbox in soup.select('input[checked]'):
print(checkbox.label.get_text())
for checkbox in soup.find_all('input', checked=True):
print(checkbox.find_next_sibling("label").get_text())
最佳答案
您应该对所有 input
元素应用 checked=True
检查。然后,获取内部 label
元素及其文本:
soup = BeautifulSoup(data, "html.parser")
for checkbox in soup.find_all('input', checked=True):
print(checkbox.label.get_text())
请注意,对于 html5lib
或 lxml
,您需要一种不同的方式来获取标签:
soup = BeautifulSoup(data, "html5lib")
for checkbox in soup.find_all('input', checked=True):
print(checkbox.find_next_sibling("label").get_text())
在你的输入数据上为我工作:
In [1]: from bs4 import BeautifulSoup
In [2]: data = """your HTML here"""
In [3]: soup = BeautifulSoup(data, "html.parser")
In [4]: for checkbox in soup.find_all('input', checked=True):
...: print(checkbox.label.get_text())
