I want to parse an html file and extract my router's IP address. I
wrote this code and I have python 2.3 installed:
#! /usr/bin/env python
import HTMLParser
class HP(HTMLParser.H TMLParser):
def handle_starttag (self, tag, data):
print "tag is %s." % (tag)
def handle_comment( self, data):
print "caught a comment: %s." % (data)
def handle_data(sel f, data):
if "IP" in data:
print "Caught %s." % data
hp = HP()
out = open('routersta tus.html')
for line in out:
hp.feed(line)
I figured that when I ran this on the html code at the bottom of this
file, it would print every tag, but instead, this is what I got:
tag is html.
tag is head.
tag is meta.
tag is meta.
tag is meta.
tag is meta.
tag is meta.
tag is title.
tag is link.
tag is script.
tag is body.
tag is form.
The program seems to take a vacation after the opening form tag. What
am I doing wrong?
Finally, this is the html code I am trying to parse:
<html>
<head>
<meta http-equiv="content-type" content="text/html;charset=IS O-8859-1">
<meta name="generator " content="Adobe GoLive 5">
<META http-equiv='Pragma' CONTENT='no-cache'>
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
<META http-equiv='Refresh' CONTENT='20'>
<title>router form</title>
<link rel="stylesheet " href="form.css" >
<script language="javas cript" type="text/javascript">
<!-- hide script from old browsers
function loadhelp(num) {
parent.helpfram e.document.loca tion.href="help/help"+num+".htm l"
}
function newwindow(F)
{
if((F.status.va lue =="checked")||( F.EncapPTelstra .value=="checke d")||(F.EncapAo lDhcp.value=="c hecked"))
window.open('en atherstatus.htm ', 'enstatherstatu s', 'width=380,heig ht=450,status=y es');
else if((F.EncapPPTP .value =="checked"))
window.open('pp tpstatus.htm', 'pptpstatus', 'width=380,heig ht=320,status=y es');
else
window.open('pp poestatus.htm', 'pppoestatus', 'width=380,heig ht=320,status=y es');
