我是Python新手,而BeautifulSoup也跟我一起......
我正在尝试弄清楚如何使用Beautifulsoup4从HTML文件中删除Doctype,但似乎无法弄清楚如何实现这一目标。
def saveToText(self):
filename = os.path.join(self.parent.ReportPath, str(self.parent.CharName.text()) + "_report.txt")
filename, filters = QFileDialog.getSaveFileName(self, "Save Report", filename, "Text (*.txt);;All Files (*.*)")
if filename is not None and str(filename) != '':
try:
if re.compile('\.txt$').search(str(filename)) is None:
filename = str(filename)
filename += '.txt'
soup = BeautifulSoup(self.reportHtml, "lxml")
try: # THROWS AttributeError IF NOT FOUND ..
soup.find('font').extract()
except AttributeError:
pass
try: # THROWS AttributeError IF NOT FOUND ..
soup.find('head').extract()
except AttributeError:
pass
soup.html.unwrap()
soup.body.unwrap()
for b in soup.find_all('b'):
b.unwrap()
for table in soup.find_all('table'):
table.unwrap()
for td in soup.find_all('td'):
td.unwrap()
for br in soup.find_all('br'):
br.replace_with('\n')
for center in soup.find_all('center'):
center.insert_after('\n')
for dl in soup.find_all('dl'):
dl.insert_after('\n')
for dt in soup.find_all('dt'):
dt.insert_after('\n')
for hr in soup.find_all('hr'):
hr.replace_with(('-' * 80) + '\n')
for tr in soup.find_all('tr'):
tr.insert_before(' ')
tr.insert_after('\n')
print(soup)
except IOError:
QMessageBox.critical(None, 'Error!', 'Error writing to file: ' + filename, 'OK')
我尝试使用:
from bs4 import Doctype
if isinstance(e, Doctype):
e.extract()
但是抱怨'e'是一个未解决的参考。我搜索了文档和谷歌,但我没有找到任何有用的东西。
另外,有没有办法减少此代码?
答案 0 :(得分:0)
这似乎可以完美地解决问题。
from bs4 import BeautifulSoup, Doctype
for item in soup.contents:
if isinstance(item, Doctype):
item.extract()
