text formatting...

  Hi,
  
  : i have a fairly simple perl issue, and i was wondering if you guys
  : could help me:
  : i used code like this to format a textarea for html:
  : ($text = $input{'text'});# =~ s/
  //g;
  : the issue is, it still puts a line break before the . however, if i
  : were to change the code to (i know b/c i was writing to html and i
  : checked the source code):
  : ($text = $input{'text'});# =~ s/?//g;
  : if would replace every "?" with a tag, as it should, without
  : putting a line break. thus, it seems like the error is something
  : unique to the
  character. all i want is to turn my multiline
  : string variable into 1 line with tags interspersed somewhere in the
  : middle. do you know of any way i could just delete those line breaks
  : and make the variable a string with no line breaks? thank you for
  : any help...
  
  Hmmm... Could it be anything to do with that some OSes use two characters for linebreaks.
  and
  . If you try stripping
  chars too it may work.
  
  $text = $input{'text'} =~ s/
  //g;
  
  On the other hand, I could me miles off.
  
  : ps: how do i access one character of a string variable?
  : is it: $mystr[7]?
  Use the substr function. $seventhchar = substr($mystr, 6, 1);
  Note 6 not 7 - as I remember it the first char is identified as 0 and not 1. There may be another way. :-)

  thanks for the tip, but it didn't work. i tried checking for
  independently and removing it, but the line breaks didn't go away... anyone else have any ideas?

  yeah, i knew about this, but i was wondering if there was a simpler way like there is in C++...
  
  thanks for any more help...

  Try escaping the '
  ' like this:
  s/\n/
  /g
  
  X

  Maybe instead of
  s/
  //g;
  you should use
  s/[
  ]+//g;
  
  It probably won't help because I'm just learning regexes, but maybe you just overlooked that in your expertise

  actually, in response to all this, i forgot to write what i did. i solved it. i just wrote a loop that went through the string i had one character at a time and added the character on to a new string. if it found a line break, it added "
  " instead of the line break...
  
  it worked like a charm...

  PS. you can access each character in a string by splitting it by a blank delimeter into array first, like this,
  
  @str_array = split(//,$my_str);#there must be NO space between the two slashes
  
  and now you can access each character by calling $str_array[0], $str_array[1], ...
  
  hope that might help ^_^
