SimpleXML 似乎没有加载任何东西...？

这真让我困惑。我以前从未使用过 XML，所以我只是在玩（当然是半夜......！）

代码：

$xml_string = "<?xml version="1.0" encoding="utf-8" ?><result>
    <status>fail</status>
    <error>
        <code>192</code>
        <message>Previous command still being processing</message>
    </error>
</result>"
$rss = simplexml_load_string($xml_string);
print $rss->result->status;

我有点困惑......我读过的每个教程似乎都表明这一点这将打印“失败” - 但它没有......？有人能指出我正确的方向吗？

This is really baffling me. I've never used XML before, so I'm just playing about (it's the middle of the night of course...!)

The code:

$xml_string = "<?xml version="1.0" encoding="utf-8" ?><result>
    <status>fail</status>
    <error>
        <code>192</code>
        <message>Previous command still being processing</message>
    </error>
</result>"
$rss = simplexml_load_string($xml_string);
print $rss->result->status;

I'm kinda baffled... Every tutorial that I have read seems to suggest that this will print "fail" - but yet it doesn't...? Can someone point me in the right direction?

有一些错误：

解决这个问题要么逃避双重

result 节点是
要打印 fail 文档，您需要：
```
print $rss->status;
```

查看

为提示您始终可以通过执行 print_r($rss); 转储 XML 对象的内容

There are some errors:

You are quoting your string in double
quotes but there are unescaped double
quotes inside the string which
prematurely terminate your string. To
fix this either escape the double
quotes inside the string or use
single quote or here doc.
The result node is the root of the
document so to print fail you need:
```
print $rss->status;
```

See it

As a tip you can always dump the content of the XML object by doing print_r($rss);
