Code:

alias striptags { return $regsubex($$1,/\[ $iif($prop == strict,style \40) .+?\]/gx,) }

I've added a .strict property to make it only remove [style] tags. If you suppress .strict it will remove all tags, including [b], [i], etc..

To see the difference try this example:

Code:

alias test {
  var %tags = [b][i]l[style co:#040404;b;]i[style co:#080808;b;]k[style co:#0C0C0C;b;]e [style co:#141414;b;]t[style co:#181818;b;]h[style co:#1C1C1C;b;]i[style co:#202020;b;]s [style co:#282828;b;]o[style co:#2C2C2C;b;]n[style co:#303030;b;]e [style co:#383838;b;]l[style co:#3C3C3C;b;]a[style co:#404040;b;]l[style co:#444444;b;]a[style co:#484848;b;]l[style co:#4C4C4C;b;]a[style co:#505050;b;]l[style co:#545454;b;]a[style co:#585858;b;]l
  echo -a Strict: $striptags(%tags).strict 
  echo -a Normal: $striptags(%tags)
}

pouncer P	i found some problems because its only supposed to remove style tags for e.g Code: var %tags = [[]root[][][[[]] echo -a Normal: $striptags(%tags) Normal: root] it should give [[]root[][][[[]] becasue there arent any style tags in it sorry i should have been more clear in my first post. i only want to remove the style tags which look like [style attributes]some text here[/style] Last edited by pouncer; 23/09/07 06:28 PM.

pouncer P	another problem: var %tags = :[style ff:Comic Sans MS;co:#4B0082;b;]hellooo[/style] echo -a $striptags(%tags).strict gives me :hellooo[/style] any idea why it puts the extra [/style] on?

thanks, im still getting some style echos though, for example

Code:

alias striptags { return $regsubex($$1,/\[ $iif($prop == strict,(?:style \40|/style)) .*?\]/gx,) }

alias test {
  var %tags = :[Style ff:Maiandra GD;co:#81CB41;b;](F)(¯`·.[style co:#ff0000;b;i;](L)(¯`·.(F)(r*)[style co:#4eee94;b;](\\\\_pony_1_//)(r*)[style co:#ff0000;b;i;](F).·´¯)(L)[style co:#7d26cd;b;i;].·´¯)(F)[/style]

  echo -a Strict: $striptags(%tags).strict
}

it echos

Strict: :[Style ff:Maiandra GD;co:#81CB41;b;](F)(¯`·.(L)(¯`·.(F)(r*)(\\\\_pony_1_//)(r*)(F).·´¯)(L).·´¯)(F)

I basically used it here because it's easier than using $+
