Why doesn't Python save to excel as it should?

Question

Python

There is a code that parses the forum page.
Essence: parses information about the user, a link to his profile and the message that the user left, saves all this in Excel.
But the problem is this, the list of users is created in the file as normal as links to their profile, but the message itself binds only the first from the page, well, or that

from urllib.request import urlopen
from urllib.parse import urljoin
from bs4 import BeautifulSoup
from time import sleep
from lxml.html import fromstring
from lxml.etree import XMLSyntaxError
import xlsxwriter

URL = 'http://www.banki.ru/forum/?PAGE_NAME=read&FID=51&TID=150146'
ITEM_PATH = '.forum-user-name'
DESCR_PATH = '.forum-post-entry'

def parse_posts():
  f = urlopen(URL)
  list_html = f.read().decode('cp1251')
  list_doc = fromstring(list_html)
  posts = []
  for elem in list_doc.cssselect(ITEM_PATH):
    a = elem.cssselect('a')[0]
    href = a.get('href')
    url = urljoin(URL, href)
    title = a.get('title')
    name = a.text_content()

    descr = list_doc.cssselect(DESCR_PATH)[0].text_content()

    post = {'name': name, 'url': url, 'descr': descr}
    
    posts.append(post)
  return posts	
    
def export_excel(filename, posts):
  workbook = xlsxwriter.Workbook(filename)
  worksheet = workbook.add_worksheet()
  
  bold = workbook.add_format({'bold': True})
  field_names = ('Название темы', 'URL', 'ДиФ')
  for i, field in enumerate(field_names):
    worksheet.write(0, i, field, bold)
    
  fields = ('name', 'url', 'descr')
  for row, post in enumerate(posts, start=1):
    for col, field in enumerate(fields):
      worksheet.write(row, col, post[field])
  workbook.close()
      
      
def main():
  posts = parse_posts()
  export_excel('posts1.xlsx', posts)
  
if __name__ == '__main__':
  main()

Essence: parses information about the user, a link to his profile and the message that the user left, saves all this in Excel.
But the problem is this, the list of users is created in the file as normal as the links to their profile, but the message itself binds only the first from the page, well, or the message on the account that you change in this piece of code. Removing [0] generally gives an error

descr = list_doc.cssselect(DESCR_PATH)[0].text_content()

It is necessary that, respectively, the user has a link and his message.
Please help, I've been stuck here for two days...

for post in list_doc.cssselect('.forum-post-table'):
    user = post.cssselect('.forum-user-name a')[0]
    name = user.text_content()
    url = urljoin(URL, user.get('href'))
    # title = user_name.get('title')
    descr = post.cssselect('.forum-post-text')[0].text_content()

Sketched on the knee. Haven't tested it in combat. Even if there are some errors, then, I hope, I conveyed the essence.
