Doesn't work if there is, somewhere after, the string `id="dgVeriler"`. You should make your regex ungreedy by adding `?` after the `.*` like `.*?`.

sure, after adding something else, but for <table class="tdicerik" id="dgVeriler", should be ok. Author dont mention what he want :) only say "match", so.. this regex match to his string.

You forgot a dot:
<table\s.*\sid="dgVeriler"
would have worked.
<table\s+.*?\s+id="dgVeriler"
would have been better (making the repetition lazy, matching as little as possible).
<table\s+[^>]*?\s+id="dgVeriler"
would have been better still (making sure that we don't accidentally match outside of the <table>tag).
And not trying to parse HTML with regular expressions, using a parser instead, would probably have been best.
