织梦CMS采集时keywords字段无法添加过滤规则的解决方法

{dede:trim replace=''}(.*){/dede:trim}

过滤规则无效。查看了下，附上解决办法：

修改include/dedecollection.class.php,717行:

 

  $keywords = preg_replace("#".$this->artNotes['keywordtrim']."#isU",'',$keywords);

为：

 

  $keywords = preg_replace("/".$this->artNotes['keywordtrim']."/isU",'',$keywords);
