XML Parse Error - Extra content at the end of the document
提问by JD Vangsness
I am trying to give the option to get either a JSON or XML response.
我正在尝试提供获取 JSON 或 XML 响应的选项。
JSON works fine but when I view the XML, I get an error.
JSON 工作正常，但当我查看 XML 时，出现错误。

I'm not sure what is going wrong. I have searched and the only thing I see is to make sure that I don't have any extra whitespace or even have spaces in my element names, which I don't.
我不确定出了什么问题。我已经搜索过，我看到的唯一一件事是确保我的元素名称中没有任何多余的空格，甚至没有空格，而我没有。

Any help would be much appreciated!

XML can only have one "document entity" or "root", you're trying to use two (statusand format). Wrap your two elements in a single one, so that your XML document only has one root element.
XML 只能有一个“文档实体”或“根”，您正在尝试使用两个（status和format）。将两个元素合二为一，这样您的 XML 文档就只有一个根元素。
Bad
坏的
<?xml version="1.0"?>
<status>success</status>
<format>xml</format>
Good
好的
<?xml version="1.0"?>
<response>
<status>success</status>
<format>xml</format>
</response>

Make sure you also triple check for a duplicate urlset declaration at the top of your document. This was my problem. It was a very careless oversight.
确保您还三重检查文档顶部是否有重复的 urlset 声明。这是我的问题。这是一个非常粗心的疏忽。
