DEDE采集时自动生成摘要和关键字

1、修改 include/dedecollection.class.php

//自动分析关键字和摘要 
preg_match("/<meta[s]+name=['"]keywords['"] content=['"](.*)['"]/isU",$this->tmpHtml,$inarr); 
preg_match("/<meta[s]+content=['"](.*)['"] name=['"]keywords['"]/isU",$this->tmpHtml,$inarr2); 
if(!isset($inarr[1]) && isset($inarr2[1])) 
{ 
$inarr[1] = $inarr2[1]; 
}

用下面一段代码替换上面的

//自动分析关键字和摘要 
preg_match("/<meta[s]+name=['"]keywords['"] content=['"](.*)['"]/isU",$this->tmpHtml,$inarr); 
preg_match("/<meta[s]+content=['"](.*)['"] name=['"]keywords['"]/isU",$this->tmpHtml,$inarr2); 
preg_match("/<meta[s]+name=keywords content=['"](.*)['"]/isU",$this->tmpHtml,$inarr3); 
if(!isset($inarr[1]) && isset($inarr2[1])) 
{ 
$inarr[1] = $inarr2[1]; 
} 
if(!isset($inarr[1]) && isset($inarr3[1])) 
{ 
$inarr[1] = $inarr3[1]; 
}

改了上面的， 还有另一个地方需要修改的，网站描述部分

preg_match("/<meta[s]+name=['"]description['"] content=['"](.*)['"]/isU",$this->tmpHtml,$inarr); 
preg_match("/<meta[s]+content=['"](.*)['"] name=['"]description['"]/isU",$this->tmpHtml,$inarr2); 
if(!isset($inarr[1]) && isset($inarr2[1])) 
{ 
$inarr[1] = $inarr2[1]; 
}

用下面的代码替换掉上面的：

preg_match("/<meta[s]+name=['"]description['"] content=['"](.*)['"]/isU",$this->tmpHtml,$inarr); 
preg_match("/<meta[s]+content=['"](.*)['"] name=['"]description['"]/isU",$this->tmpHtml,$inarr2); 
preg_match("/<meta[s]+name=description content=['"](.*)['"]/isU",$this->tmpHtml,$inarr3); 
if(!isset($inarr[1]) && isset($inarr2[1])) 
{ 
$inarr[1] = $inarr2[1]; 
} 
if(!isset($inarr[1]) && isset($inarr3[1])) 
{ 
$inarr[1] = $inarr3[1]; 
}
