从SimpleXML访问@attribute [英] Accessing @attribute from SimpleXML

问题描述

访问我的SimpleXML对象的@attribute部分时遇到问题.当我var_dump整个对象时，我得到正确的输出，而当我var_dump其余对象(嵌套标签)时，我得到正确的输出，但是当我遵循docs和var_dump ，尽管第一个var_dump清楚地表明存在要输出的属性，但我还是得到了一个空对象.

I am having a problem accessing the @attribute section of my SimpleXML object. When I var_dump the entire object, I get the correct output, and when I var_dump the rest of the object (the nested tags), I get the correct output, but when I follow the docs and var_dump $xml->OFFICE->{'@attributes'}, I get an empty object, despite the fact that the first var_dump clearly shows that there are attributes to output.

任何人都知道我在这里做错了/如何进行这项工作?

Anyone know what I am doing wrong here/how I can make this work?

推荐答案

您可以通过在XML节点上调用attribute()函数来获取XML元素的属性.然后，您可以var_dump函数的返回值.

You can get the attributes of an XML element by calling the attributes() function on an XML node. You can then var_dump the return value of the function.

该页面上的示例代码:

$xml = simplexml_load_string($string);
foreach($xml->foo[0]->attributes() as $a => $b) {
    echo $a,'="',$b,"\"\n";
}
