error gt lt quot simplexml

PHP正则
现在要用正则取出里面 17
 


17
同步发送即时短信返回结果


我是这样写的
preg_match("/\(.*)\/U",$string,$state);

但是输出:
Array
(
  [0] => 17
  [1] => 17
)

哪些错了啊,还有我用
simplexml_load_string解析这个XML报错,本想用这个函数取这个节点,但是不行,现在只能用正则了
表帮帮忙,谢谢。

------解决方案--------------------
1.正则没错。
你可以用$state[1]获取到error节点的值。

2.simplexml_load_string()如果报错。很可能是文件BOM头的原因或者编码不一致原因。
------解决方案--------------------
你那个输出时正确的
------解决方案--------------------
你的正则没有错,你取$state[1]就行了 前面那个不用理会

你用simplexml_load_string报错 八成是xml里面的换行符 回车符导致的 把它们都替换掉

PHP code

$xml='<?xml version="1.0" encoding="UTF-8"?>
<response>
<error>17</error>
<message>同步发送即时短信返回结果</message>
</response>';

$obj=simplexml_load_string(str_replace(array("\r","\n","\t"),'',$xml));
print_r($obj);
<br><font color="#e78608">------解决方案--------------------</font><br>$xml = simplexml_load_string($s);<br>echo $xml->error;<br><br>如果出错,是因为你的编码不合适<br> <div class="clear">
                 
              
              
        
            </div>
