- How bout gaps in the HTML file? do we have to account for that? <html> <--- gap? <header> what do u mean? find a < and get it plus everything before and including the >. use paul gries' webpage as a sample. |

but gaps are null ...
your file is supposed to end when they're null ?
it says that "... that implements interface java.util.Iterator and that iterates through the tags in a BufferedReader until readLine() returns null."
....................................................
if you were to consider them, then how would you differenciate the end of the file and a gap ?

just not sure because he says that if we want extra samples to play with .. then we should use his website html .. and his website html ~pgries.htm is filled with gaps !!!  What does everyone else think? and how did everyone else do it ? |

Gaps aren't null. Null is end of file.

sorry .. gaps isn't a very precise word
hmm... a blank line?
<html>
<head>
if you go readLine() between <html> and <head> .. then it gives a null.

it shouldn't affect anything as long as u keep looping until u find the end tab

A blank line/gap is called an empty string. Null and empty string are not the same.
String s = "": //an empty string
String s = null; //a string that points to nothing. ie. null

it does..
Bahamut have you tried with yours? cause unless my readLine() thing is messed up .. .that's what its doing..
I thought it wouldn't read as a null .. but so far what I'm thinking is wrong !

>>>Bahamut have you tried with yours? cause unless my readLine() thing is messed up .. .that's what its doing.. <<< I tested for every conceivable combination.  I've tested this case and it works. Try checking your IF statements, it sounds like your problem is within those buggers. But remember, tattoo this in your brain, that an empty String and a null String are not the same. |
