推荐答案

我认为您的问题是您在该脚本中推出的不仅仅是 XML.您首先将内容类型设置为 XML 并 echoing XML 声明，但之后您开始 echo 看起来像调试命令的内容，它们不是有效的 XML，所以解析器会抛出一个错误.

I think your problem is that you're pushing out more than just XML within that script. You start by setting the content type to XML and echoing the XML declaration, but after that you start to echo what looks like debugging commands, which aren't valid XML, so the parser throws an error.

所以，首先，我会从脚本中注释掉或删除任何 echo 非 XML 内容的内容.

So, to start, I would comment out or remove anything that echos non XML content from your script.

如果这有帮助，请告诉我.

Let me know if that helps.
