Python crawler crawls data within td tags with only onclick attributes and gets onclick content

problem description

I want to crawl the contents of all the td tags in the tr tag and get the absolute path within the onclick attribute

the environmental background of the problems and what methods you have tried

try to directly ignore onclick to crawl the contents of td tags in all tr tags. Test is successful
attempt to crawl onclick content first, ignore headers (that is, < tr class="fist >), both failed

import requests
from bs4 import  BeautifulSoup
import re
headers = {"User-Agent":"Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36",
           "Host":"www.pgskpw.com"}
link = "http://www.pgskpw.com/"
r = requests.get(link,headers = headers,timeout = 20)
soup = BeautifulSoup(r.text,"html.parser")
user_information = re.compile(r"javascript：window.open("/personal_show.php?showid=");readent(this);")
person_book = soup.find("div",class_="conBox listbox mb10")
person_list = person_book.find_all("tr",attrs={"onclick":user_information})
for i in person_list:
    print(i)
