Re: [Htmlparser-user] Hints on how to change image tag locations and writeoutdocument

[Raghavender S. <kin...@ho...>]

Hi Somik,
I was using the 1.1 version of htmlparser. I save the www.yahoo.com content 
in a flat file yahoo.txt. and I run the parser against this. throws a 
nullpointerexception in HTMLScriptScanner. this seems to be a new addition 
for 1.1. I will send the stacktrace, the main program and the yahoo.txt.
actually I cannot send the stacktrace. I made some changes and the line 
numbers dont match. but if you run this program you would see the 
nullpointerexception.
Thanks,
Raghav

Re: [Htmlparser-user] Hints on how to change image tag locations andwriteoutdocument

[Somik R. <so...@ya...>]

Hi Raghav,
    On analyzing yahoo.txt, I found that you have incorrect html. There =
is a script tag that has not been closed. So naturally the script =
scanner goes bonkers. Rename the extension to .html, and open this file =
in IE, and you will find that IE also cant handle this.
    I verified from www.yahoo.com, and found that they do have the =
correct </script> tag provided. So I guess your yahoo.txt file is =
faulty.

Regards,
Somik
