Try something along this line:
<?php preg_match_all('/<a\b/Ui',$text,$matches); ?>
Replace $text with the text through which you want to look, and
your results will be an array in $matches. The \b switch in the
regexp will match any word/letter border, which includes whitespaces,
tabs, newlines, periods, et cetera. Essentially, anything that you'll
want to match inside HTML tags, be they valid or otherwise. The U
modifier makes the search "Ungreedy," while the i modifier makes it
case-iNsEnSiTiVe.
