求dingsongtao大哥帮我解决一个问题

在我获取的一段HTML内容中，有以下内容很多条：<tr><td class="cols01">¥710 
经济舱 <a href="javascript:void(0)" method="moreflight" itemid="1" flightNo="CA1559" flightclass="Y" datacache="0" >所有舱位</a></td><td>.....</td>......</tr><tr><td class="cols01">¥810 
经济舱 <a href="javascript:void(0)" method="moreflight" itemid="1" flightNo="MA1578" flightclass="Y" datacache="0" >所有舱位</a></td><td>.....</td>......</tr>我写了以下代码来提取上面的红色部分：$html = preg_replace('/>(\s+)/','>',$html);
$html = preg_replace('/(\s+)</','<',$html);
$html = str_replace("\r\n",'',$html);
$html = str_replace("\t",'',$html);
$result=array();
$lowerPrice = array();preg_match_all('~<tr><td class="cols01">¥(.*?)(.*?) <a href="javascript:void$0$" method="moreflight" itemid="1" flightNo="(.*?)" flightclass="Y" datacache="0" >(.*?)</a></td>~is',$html,$data);foreach($data[1] as $key=>$item){
 $result[$key]["price"]=$item;
}
foreach($data[3] as $key=>$item){
 $result[$key]["flyno"]=$item;
}
print_r($result);
但是却得不到。求dingsongtao大哥赐教! 谢谢

用这个正则<tr><td class="cols01">¥(.*?)(.*?) <a href="javascript:void$0$" method="moreflight" itemid="1" flightNo="(.*?)" flightclass="Y" datacache="0" >(.*?)</a></td>
//比较傻的办法，$str = str_replace(array("\r", "\n", ' '), '', $str);
echo htmlspecialchars($str) . ' ';
preg_match_all("'<tr><td class=\"cols01\">¥(.*?)(.*?) <a href=\"javascript:void$0$\" method=\"moreflight\" itemid=\"1\" flightNo=\"(.*?)\" flightclass=\"Y\" datacache=\"0\" >(.*?)</a></td>'isx",$str,$data);print_r($data);
哦，原来的应该是$html，，，，我这弄成了$str,测试注意下，，，，
$html = '<tr><td class="cols01">¥710 
经济舱 <a href="javascript:void(0)" method="moreflight" itemid="1" flightNo="CA1559" flightclass="Y" datacache="0" >所有舱位</a></td><td></td></tr><tr><td class="cols01">¥810 
经济舱 <a href="javascript:void(0)" method="moreflight" itemid="1" flightNo="MA1578" flightclass="Y" datacache="0" >所有舱位</a></td><td></td></tr>
';$html = preg_replace('/>(\s+)/','>',$html);
$html = preg_replace('/(\s+)</','<',$html);
$html = preg_replace('/(\s+)/',' ',$html);
$html = str_replace("\r\n",'',$html);
$html = str_replace("\t",'',$html);
echo $html;
echo "<pre>";
$result=array();
preg_match_all('~<tr><td class="cols01">¥(.*?)(.*?)~is',$html,$data);
foreach($data[1] as $key=>$item){
$result[$key]["money"]=$item;
}
foreach($data[2] as $key=>$item){
$result[$key]["tax"]=$item;
}preg_match_all('~<a[^>]*?href="javascript:void$0$"[^>]*?flightNo="(.*?)"[^>]*?>所有舱位</a>~is',$html,$data);
foreach($data[1] as $key=>$item){
$result[$key]["flightNo"]=$item;
}
print_r($result);
错了，是我在 加了一个空格，下面那个删掉了一个空格，我用红色标识出来的，你晕毛啊，我这里是可以的
