刚开始碰php,解析xml时碰到问题了

本帖最后由 yxxue 于 2012-11-25 18:57:42 编辑 远程XML文档格式如下:
<br />
<?xml version="1.0" encoding="UTF-8" ?> <br />
 <user><br />
  <data errorcode="0" usernum="100626" <br />
username="u1" sex="1" nickname="麦芽糖" <br />
score="0" province="" city="" area="" /> <br />
  </user><br />


我在PHP中这样获取到这个XML:
使用自己写的gethttpdata方法,是为了容错,避免访问远程服务器出错时程序报错。
<br />
$login_interface_url = "http://www.1.com/1.xml";<br />
	$data = gethttpdata($login_interface_url); //获取远程文件内容<br />
	$xml = simplexml_load_string($data);<br />
	$xmldata = var_export($xml,true);<br />
        //如果使用var_dump()就直接输出了,不是我想要的。<br />
<br />


接下来我怎么读取这个xmldata呢?
如何获得中的各个属性的值呢?

本帖最后由 xuzuning 于 2012-11-25 22:28:58 编辑 默认是 utf-8 的
$string = <<<XML<br />
<?xml version="1.0" encoding="gb2312" ?> <br />
<a><br />
<foo name="Jack" game="lonely">1</foo><br />
<foo name="千斤顶" game="寂寞">1</foo><br />
</a><br />
XML;<br />
<br />
$xml = simplexml_load_string($string);//但也可以接受非 utf-8 声明的xml<br />
foreach($xml->foo as $item) {<br />
  foreach($item->attributes() as $a => $b) {<br />
    echo $a,'="',$b,"\"\n";<br />
  }<br />
}

但结果还是 utf-8 的
name="Jack"
game="lonely"
name="千斤顶"
game="寂寞"
