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

问题描述

我在访问 SimpleXML 对象的 @attribute 部分时遇到问题.当我 var_dump 整个对象时，我得到了正确的输出，而当我 var_dump 对象的其余部分(嵌套标签)时，我得到了正确的输出，但是当我按照文档和 var_dump $xml->OFFICE->{'@attributes'}，我得到一个空对象，尽管第一个 var_dump 清楚地表明有输出的属性.

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.

有人知道我在这里做错了什么/我怎样才能做到这一点吗?

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 attributes() 函数来获取 XML 元素的属性.然后你可以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.
