这是我对strip_tags函数的实现:
CREATE FUNCTION `strip_tags`($str text) RETURNS text
BEGIN
DECLARE $start, $end INT DEFAULT 1;
LOOP
SET $start = LOCATE("<", $str, $start);
IF (!$start) THEN RETURN $str; END IF;
SET $end = LOCATE(">", $str, $start);
IF (!$end) THEN SET $end = $start; END IF;
SET $str = INSERT($str, $start, $end - $start + 1, "");
END LOOP;
END;
我确保它删除了不匹配的左括号,因为它们很危险,尽管它忽略了任何未配对的右括号,因为它们无害。
mysql> select strip_tags('<span>hel<b>lo <a href="world">wo<>rld</a> <<x>again<.');

| strip_tags('<span>hel<b>lo <a href="world">wo<>rld</a> <<x>again<.') |

| hello world again. |

这些行添加到fnStripTags功能
后SET Dirty = Insert( Dirty, iStart, iLength, '');
set Dirty = Replace(Dirty,' ',''); #No space between & and nbsp;
set Dirty = Replace(Dirty,'\r','');
set Dirty = Replace(Dirty,'\n','');
