使用正则表达式捕获不同的语法

I'll have code embedded in HTML, it will look something like this:

<div id="someDiv">
{:
    HTMLObject
    id: form
    background: blue
    font: large
    fields [
        username: usr
        password: pwd
    ]

    foo: bar
:}
</div>

I am trying to write a regular expression that will take these HTMLObjects and break them into manageable arrays. I already have the regexp that will do the lines such as

id: form

However, I'm having trouble with making the regexp also match ones like

fields [
    username: usr
    password: pwd
]

Here is the function I have that performs these tasks:

function parseHTMLObjects($html) {
    $details = preg_replace('/[{:]([^}]+):}/i', '$1', $html);
    $details = trim(str_replace('HTMLObject', '', $details));

    $dynamPattern = '/([^\[]+)\[([^\]]+)]/';
    $dynamMatch = preg_match_all($dynamPattern, $details, $dynamMatches);

    print_r($dynamMatches); // nothing is shown here

    $findMatch = preg_match_all('/([^:]+):([^
]+)/', $details, $matches);

    $obs = array();
    foreach($matches[0] as $o) {
        $tmp = trim($o);
        echo $tmp . "
";
    }
}

When I pass an HTML string like I demonstrated at the beginning of the page, the $findMatch regexp works fine, but nothing gets stored in the dynams one. Am I going about this in the wrong way?

Basically all I need is each object stored in an array, so from the sample HTML string above, this would be an ideal array:

Array() {
    [0] => id: form
    [1] => background: blue
    [2] => font: large
    [3] => fields [
               username: usr
               password: pwd
           ]
    [4] => foo: bar
}

I have all the sorting and manipulation handled beyond that point, but like I said, I'm having trouble getting the same regexp that handles the colon style objects to also handle the bracket style objects.

If I need to use a different regexp and store the results in a different array that is fine too.

    It would be easly made with some black sorcery called YAML or JSON with these syntaxes:

    YAML

    {:
        HTMLObject:
          id: form
          background: blue
          font: large
          fields: [
            username: usr,
            password: pwd
          ]
          foo: bar
    :}
    

    JSON

    {:
        { 
          "HTMLObject":{
            "id": "form",
            "background": "blue",
            "font": "large",
            "fields": [
              {"usernamd": "usr"},
              {"password": "pwd"}
            ],
            "foo": "bar"
          }
        }
    :}
    

    Bu-bu-but why? 'Cuz it's natively parsed. No dirty RegExps.
