y cómo extraer datos si en la noticia tengo letras en negrilla, subralladas o si en la noticia hay links. Ese comando solo funciona para ...

y logré hacerlo. En vez de terminar el xpath del body con 'text()' lo elimino. Y luego, cuando veo los párrafos uso el comando text_content()

import requests
import lxml.html as html # para aplicar Xpath a HTML
import os
import datetime

HOME_URL = 'https://www.elcomercio.com/'


XPATH_LINK_TO_ARTICLE = '//h3[@class="article-highlighted__title"]/a/@href' #links of each of the news
XPATH_TITLE = '//h1[@class="entry__title"]/text()'
XPATH_BODY = '//div[@class="entry__content"]/p'

def parse_notice(link, today):
    try: 
        response =  requests.get(link)
        if response.status_code == 200:
            notice = response.content.decode('utf-8')#trae el html de la noticia
            parsed = html.fromstring(notice)

            try:
                title =  parsed.xpath(XPATH_TITLE)[0]#extract title
                #title = title.replace('\"', '')#deletes the character "
                print(title)

                body =  parsed.xpath(XPATH_BODY)

                for i in body:
                    print(i.text_content())

            except IndexError:
                print('ha habido un error')
                return
            '''
            with open(f'{today}/{title}.txt', 'w', encoding='utf-8') as f:
                f.write(title)
                f.write('\n\n')
                f.write(summary)

            home = response.content.decode('utf-8')
