本文为一个提取一批新闻网页中的文本的小程序,它可以将各篇新闻的内容存为以该新闻标题为文件名的文本文件。如有更好的处理方法,请和我联系:
lwx3069@sina.com
   这里以人民网中的“今日要闻”下的新闻为例.
($url) ? "" : $url = "http://www.unn.com.cn/GB/channel2/3/11/index.html";        // 今日要闻
if(isset($url)&&$url!="")        {
   $str = implode("",file($url));
   $str_ary = explode("
    ",$str);
       $str_ary = explode("
  • ",trim($str_ary[1]));
       for ($i=0; $i      if (strlen(trim($str_ary[$i]))      continue;
          }
          echo "新闻".$i.":".$str_ary[$i];
          $str1=strstr("$str_ary[$i]",'      $len1=strlen("$str1");
          $len2=strlen("$str2");
          $len=$len1-$len2;
          $url=substr("$str1",10,$len-10);
          if (strlen(trim($url))!=0) {
             $url = "http://www.unn.com.cn/".$url;
             define(CONTENTS_DIR,"./contents/");
             if(isset($url)&&$url!="")        {
                $str = implode("",file($url));
                $str1=explode('
    ',$str);            //去掉文件没用的上半部分
                $str2 = explode('

     

    ',$str1[1]);
                //取出文件的下半部分,并去掉没用的下半部分,这时得到的都是有用的
                $str3=explode('',$str2[0]);   //从整个有用部分取出文件标题和正文
                $str4=explode('
    ',$str2[0]);   //取出日期和时间
                $str5=explode('',$str3[1]);     //从标题和正文部分取出标题
                $title=str_replace("
    ","",$str5[0]);
                $str3=explode('

    ',$str2[0]);          //从整个有用部分取出文件正文
                $str3[1]=str_replace('

        ',"\n"."  ",$str3[1]);
                $str3[1]=str_replace(' ',"",$str3[1]);
                $str3=strip_tags($str3[1]);
                $pf=trim($title).".txt";
                $ppf=fopen(CONTENTS_DIR."$pf",'w');
                fputs($ppf,$title);
                fputs($ppf,"$str4[0]");
                fputs($ppf,$str3);
            }
         }
      }
    }
    ?>
