参考：http://cn.php.net/preg_match_all 非常有用的正则。
<?php
// The \\2 is an example of backreferencing. This tells pcre that
// it must match the second set of parentheses in the regular expression
// itself, which would be the ([\w]+) in this case. The extra backslash is
// required because the string is in double quotes.
$html = “<b>bold text</b><a href=howdy.html>click me</a>”; preg_match_all(“/(<([\w]+)[^>]*>)(.*)(<\/\\2>)/”, $html, $matches, PREG_SET_ORDER);foreach (
$matches as $val) {
echo “matched: ” . $val[0] . “\n”;
echo “part 1: ” . $val[1] . “\n”;
echo “part 2: ” . $val[3] . “\n”;
echo “part 3: ” . $val[4] . “\n\n”;
