flatfile autoformater

[taith]

just trying to make a flatfile autoformatter... and it works... sorta... except that it splits up like tags... as

  <td>text</td>

 

becomes

  <td>text

  </td>

 

function cleanup($array){
$out=array();
foreach($array as $k=>$v){
  if(!empty($v)) $out[$k]=$v;
}
return $out;
}

function autoformat($string,$start=0){
$string=cleanup(explode('<',$string));
foreach($string as $k=>$v){
  if($string[$k]{0}!='<')$string[$k]='<'.$string[$k];
  if($string[$k]{1}=='/') $start--;
  else $start++;
  for($i=0; $i<$start; $i++) $string[$k]=' '.$string[$k];
  $string[$k].="\n";
}
return implode('',$string);
}
$string='<table><tr><td></td></tr></table>';
echo autoformat($string);

Ever thought of using the tidy extension?

 

PS; Indexing a string via $string{3} is being depericated on favour of $string[3].

$string[$k].="\n";

 

That is where the issue lies. you gotta figure out how to determine which needs to have \n after and which doesn't, which will probably need a manual array of known tags to not add the \n too.

no... i need/want to be able to do this on the fly ;-)

ya... thats the problem... i dont know how to determine if theres tags within the tags... in which i would include the next tag at the end...

You will need http://en.wikipedia.org/wiki/recursion . =)

 

EDIT:::

 

www.php.net/recursive maybe ?? if not see the wikipedia entry.

? page isnt there...

[taith]

ok... well... anybody know how to split between tags, without damaging anything?

 

eg '<table><tr><td>text</td></tr></table>'

 

becoming array('<table>','<tr>','<td>','text','</td>','</tr>','</table>')

Half-assed:

 

$tags = split(">", $tags);

 

Just remember to add the > back onto the end of the line.

ya... i could just explode it... however...

 

you get "text</td"

[per1os]

Yea unfortunately without using regex etc that is how it has to be done, unless this is trictly for tables and there will always be a </td> you can always split that up.

www.php.net/preg_match may work better as you can do something like

 

find <td> (allchars here)</td> and it will return the results in an array (i believe) of the all chars here part.

 

EDIT::

 

Found this on the user comments on www.php.net/preg_match

<?php
$string = "<td>text</td>";
$between = preg_match_between("<td>", "</td>", $string);
echo $between;

function preg_match_between($a_sStart, $a_sEnd, $a_sSubject)
{
  $pattern = '/'. $a_sStart .'(.*?)'. $a_sEnd .'/';
  preg_match($pattern, $a_sSubject, $result);

  return $result[1];
}

ya... i dont mind it splitting the text into its own segment in the array... i can join em back up... and preg_split() would prolly be the best/only viable way of doin it... i just dont get regex very well... LOL

i JUST built this... for those out there who wants it

 

function explodebytags($string){
$out=array();
for($i=0; $i<=strlen($string); $i++){
  if($string[$i]=='<'){
   for($i=$i; $i<=strlen($string); $i++){
    $temp.=$string[$i];
    if($string[$i]=='>'){
     $out[]=$temp;
     unset($temp);
     break;
    }
   }
  }else{
   for($i=$i; $i<=strlen($string); $i++){
    if($string[$i]=='<'){
     $out[]=$temp;
     unset($temp);
     $i--;
     break;
    }
    $temp.=$string[$i];
   }
  }
}
return $out;
}
