У меня есть куча HTML-документов инструментов GCOV для ветвей и линий, файлы выглядят так:

 lt;trgt; lt;td align="right" class="lineno"gt;lt;pregt;224lt;/pregt;lt;/tdgt; lt;td align="right" class="linebranch"gt;lt;span class="takenBranch" title="Branch 1 taken 329 times"gt;amp;check;lt;/spangt;lt;span class="notTakenBranch" title="Branch 2 not taken"gt;amp;cross;lt;/spangt;lt;span class="notTakenBranch" title="Branch 4 not taken"gt;amp;cross;lt;/spangt;lt;span class="takenBranch" title="Branch 5 taken 329 times"gt;amp;check;lt;/spangt;lt;br/gt;lt;span class="notTakenBranch" title="Branch 6 not taken"gt;amp;cross;lt;/spangt;lt;span class="takenBranch" title="Branch 7 taken 329 times"gt;amp;check;lt;/spangt;lt;/tdgt; lt;td align="right" class="linecount coveredLine"gt;lt;pregt;329lt;/pregt;lt;/tdgt; lt;td align="left" class="src coveredLine"gt;lt;pregt; line of C   codelt;/pregt;lt;/tdgt; lt;/trgt;  lt;trgt; lt;td align="right" class="lineno"gt;lt;pregt;225lt;/pregt;lt;/tdgt; lt;td align="right" class="linebranch"gt;lt;/tdgt; lt;td align="right" class="linecount uncoveredLine"gt;lt;pregt;lt;/pregt;lt;/tdgt; lt;td align="left" class="src uncoveredLine"gt;lt;pregt; another line of C   code;lt;/pregt;lt;/tdgt; lt;/trgt;  

Я хотел бы извлечь текст «(другая) строка кода C «, а в идеале также номер строки, чтобы вывод выглядел так:

 224 line of C   code 225 another line of C   code  

Я пытался использовать BeautifulSoup, но он не предоставляет запрошенный вывод, мой код выглядит так:

 from itertools import islice import codecs import glob from ntpath import join import os from bs4 import BeautifulSoup  lineNo = "lt;td align="right" class="lineNo"gt;lt;pregt;" linetextCovered = "lt;td align="left" class="src coveredLine"gt;lt;pregt;" linetextNotCovered = "lt;td align="left" class="src uncoveredLine"gt;lt;pregt;" open('Output.txt', 'w').close() #Erase any content of Output.txt file  for filepath in glob.iglob('path/To/Reports/*.html'):  with codecs.open(os.path.join(filepath), "r") as inputFile, open('Output.txt',"a") as outputFile:  for num, line in enumerate(inputFile, 1):  if lineNo in line:  inputSoup = BeautifulSoup(line)  text = inputSoup.getText()  outputFile.write("".join(islice(text, 1)   "t"))  if linetextCovered or linetextNotCovered in line:  inputSoup = BeautifulSoup(line)  text = inputSoup.getText()  outputFile.write("".join(islice(text, 4)))  outputFile.write("n") print("Done")  

Но результат выглядит так

 /* L a:li {  colo text }  

Что я делаю не так? Большое вам спасибо за любую помощь.

Ты можешь сделать вот так:

 from bs4 import BeautifulSoup  html = ''' lt;trgt; lt;td align="right" class="lineno"gt;lt;pregt;224lt;/pregt;lt;/tdgt; lt;td align="right" class="linebranch"gt;lt;span class="takenBranch" title="Branch 1 taken 329 times"gt;amp;check;lt;/spangt;lt;span class="notTakenBranch" title="Branch 2 not taken"gt;amp;cross;lt;/spangt;lt;span class="notTakenBranch" title="Branch 4 not taken"gt;amp;cross;lt;/spangt;lt;span class="takenBranch" title="Branch 5 taken 329 times"gt;amp;check;lt;/spangt;lt;br/gt;lt;span class="notTakenBranch" title="Branch 6 not taken"gt;amp;cross;lt;/spangt;lt;span class="takenBranch" title="Branch 7 taken 329 times"gt;amp;check;lt;/spangt;lt;/tdgt; lt;td align="right" class="linecount coveredLine"gt;lt;pregt;329lt;/pregt;lt;/tdgt; lt;td align="left" class="src coveredLine"gt;lt;pregt; line of C   codelt;/pregt;lt;/tdgt; lt;/trgt;  lt;trgt; lt;td align="right" class="lineno"gt;lt;pregt;225lt;/pregt;lt;/tdgt; lt;td align="right" class="linebranch"gt;lt;/tdgt; lt;td align="right" class="linecount uncoveredLine"gt;lt;pregt;lt;/pregt;lt;/tdgt; lt;td align="left" class="src uncoveredLine"gt;lt;pregt; another line of C   code;lt;/pregt;lt;/tdgt; lt;/trgt; '''   for tr in BeautifulSoup(html.encode(), 'html.parser').find_all('tr'):  lineno = tr.find('td',{'class':'src'}).text.strip()  src = tr.find('td', {'class':'lineno'}).text.strip()  print(lineno, src)
