kauja pret html kaitniekiem :) 

piektdien, 15.10.2004 @2:19 pm | tidliibums

Nesen sapiktojos par to, ka viens neuzmanīgs cibiņš, kurš pavisam nejauši ieraksta savā pukstā </div> (protams, bez atbilstoša atverošā <div>), var galīgi izjaukt visu manu (ārprātīgi glīto :D) layout.

(Un tabulu layout-iem droši vien kaut kas līdzīgs notiek, ja ieraksta noslēdzošo td vai tr vai table.)

Rezultātā uztapa šis te:

######################################
function validated_tag (string tag) : string {
  var string[] tagsallowed = [ "br", "br/", "br /", "/a", "/span", 
    "b", "s", "i", "code", "blockquote", "em", "strong", "p",
    "/b", "/s", "/i", "/code", "/blockquote", "/em", "/strong", "/p" ];
  var string[] tagsskipped = [ "a ", "img ", "span class=", "lj user=" ];
  var string[] tagsreplaced = [ "form ", "/form" ];
  var string[] replaceto = [ "blockquote", "/blockquote" ];

  var string tagl = $tag->lower();

  var int i = -1;
  foreach var string t ($tagsreplaced) { $i = $i + 1; if ($tagl->substr(0, $t->length()) == $t) { return "<" + $replaceto[$i] + ">"; } }

  foreach var string t ($tagsskipped) { if ($tagl->substr(0, $t->length()) == $t) { return "<" + $tag + ">"; } }
  foreach var string t ($tagsallowed) { if ($tagl == $t) { return "<" + $t + ">"; } }
# citus (neapstrādātos) tag-us vienkārši dzēšam
  return "";
}

function striphtml2 (string s) : string {
  var string result = "";
  var string curr_tag = "";
  var bool outside = true;

  foreach var string ch ($s) {
    if ($outside) {
      if ($ch == "<") { $outside = false; }
      else { $result = $result + $ch; }
    } else {
      if ($ch == ">") { $outside = true; $result = $result + validated_tag($curr_tag); $curr_tag = ""; }
      else { $curr_tag = $curr_tag + $ch; }      
    }
  }

  return $result;
}

Jā, ir samērā Quick 'n Dirty, bet savu uzdevumu it kā pilda.

Poll-iem tiek izdarīts nedaudz sāpīgi, bet man tas pat iepatikās. Tikt pie balsošanas var tik un tā, caur poll-a linku.
