Code-Schnipsel

bsobjswap = BeautifulSoup(r2.content) 
print (bsobjswap.find('table',{'id':'ctl00_cpMainContent_gvNodes'}).find("style",{"color":"Black"})) 

Das ist mein letzter Versuch, funktioniert aber nicht. Jede Hilfe ist willkommen

As installation have been done recently, Lancom uses 2.05 configuration script. Our engineer was unable to see landing page, he was getting connected to the Internet with. I contacted Picopoint who informed me that this is due the fact that their system remembers MAC addresses of the devices that were logged into the system hence no landing page is needed. It have been confirmed by removing MAC addresses of the engineer's devices from the database. By doing so engineer was able to access the landing page again. Picopoint's engineer checked the configuration of the devices at both ends and haven't detected any problems. At the moment we are unable to state what are the issues with venue as we haven't experienced any. <br /><br />Arrival Time: 02/01/2014 16:19:23<br />Leaving Time: 02/01/2014 17:51:18<br />Was the job successful: Yes<br /><br /><br />Notes:Still physically missing lines 3 and 4.

Mein Code Besuche Tausende von Seiten und es bei der Suche jede Tabelle nach dem gleichen Muster folgt und ich vermute, ich werde immer die Daten aus dem dritten td-Tag brauchen, aber nicht sicher, wie man es bekommt.

Prost

Wie sei es damit:

from bs4 import BeautifulSoup 

html = """(your html from the example above)""" 

soup = BeautifulSoup(html, 'html.parser') 

row_data = soup.find('td', {'style':'color:Black;background-color:LightSkyBlue;border-color:LightSkyBlue;font-size:12pt;font-weight:normal;'}) 

clean_data = str(row_data).replace('<td style="color:Black;background-color:LightSkyBlue;border-color:LightSkyBlue;font-size:12pt;font-weight:normal;">','')\ 
    .replace('</td>','') 

print('\n'.join([x for x in clean_data.split('<br/>') if x != ''])) 

"""
