Javascript BBCode Parser recognizes only first list element

Question

I have a really simple Javascript BBCode Parser for client-side live preview (don't want to use Ajax for that). The problem ist, this parser only recognizes the first list element:

function bbcode_parser(str) {
search = new Array(
      /\[b\](.*?)\[\/b\]/,  
      /\[i\](.*?)\[\/i\]/,
      /\[img\](.*?)\[\/img\]/,
      /\[url\="?(.*?)"?\](.*?)\[\/url\]/,
      /\[quote](.*?)\[\/quote\]/,
      /\[list\=(.*?)\](.*?)\[\/list\]/i,
      /\[list\]([\s\S]*?)\[\/list\]/i,
      /\[\*\]\s?(.*?)\n/);

replace = new Array(
      "<strong>$1</strong>",
      "<em>$1</em>",
      "<img src=\"$1\" alt=\"An image\">",
      "<a href=\"$1\">$2</a>",
      "<blockquote>$1</blockquote>",
      "<ol>$2</ol>",
      "<ul>$1</ul>",
      "<li>$1</li>");

for (i = 0; i < search.length; i++) {
    str = str.replace(search[i], replace[i]);
}

return str;}

[list]
[*] adfasdfdf
[*] asdfadsf
[*] asdfadss
[/list]

only the first element is converted to a HTML List element, the rest stays as BBCode:

adfasdfdf

[*] asdfadsf
[*] asdfadss

I tried playing around with "\s", "\S" and "\n" but I'm mostly used to PHP Regex and totally new to Javascript Regex. Any suggestions?

For multiple matches you will need to use a regular expression with the g modifier:

  /\[b\](.*?)\[\/b\]/g,  
  /\[i\](.*?)\[\/i\]/g,
  /\[img\](.*?)\[\/img\]/g,
  /\[url\="?(.*?)"?\](.*?)\[\/url\]/g,
  /\[quote](.*?)\[\/quote\]/g,
  /\[list\=(.*?)\](.*?)\[\/list\]/gi,
  /\[list\]([\s\S]*?)\[\/list\]/gi,
  /\[\*\]\s?(.*?)\n/g);

try adding the g and m switches /<regex>/gm switches to your regex patterns.
