If request is for "DIV" tags w.r.t id "Second"
over here i want to exclude table but if it contains some other html tags then i have to maintain the text with there respective tags.

extraction of data within the html tags may be with "id","class" or without there attributes.
i have extracted data between tags w.r.t id but it fails if it has some other div in between

You should really be using an HTML parser for something like this. However, since you asked about regex, you can try:

$tag = 'br';
$attr = '';

// OR

$tag = 'div';
$attr = 'class="test"';

// ******************* //

$tag = preg_quote($tag);
$attr = preg_quote($attr);

if (preg_match("/<$tag(?: +[^>]*$attr[^>]*)?>((?:<|[^<](?!/$tag))+)</$tag>/", $html, $matches) {
    echo $matches[1];
}

thx for info HTML parser can also be used.
as you have mention does it will provide right info for id second as it contains div inside div.
Even i am trying for html parser for this issue

Tried but have got this issue.

syntax error, unexpected '^', expecting T_STRING or T_VARIABLE or T_NUM_STRING

Give me a little while to test. I'm not currently near a machine with PHP installed, but I'll have one shortly. I'll post back with a correction.

OK, let's try it like this:

$tag = 'br';
$attr = '';

// OR

//$tag = 'div';
//$attr = 'class="test"';

// ******************* //

$tag = preg_quote($tag);
$attr = preg_quote($attr);

$pattern = "/<" . $tag . "(?: +[^>]*" . $attr . "[^>]*)?>((?:<|[^<](?!\/" . $tag . ">))+)<\/" . $tag . ">/";

if (preg_match($pattern, $html, $matches)) {
    echo $matches[1];
}
