XML解析错误：文档末尾的额外内容-XMLParsingerror:Extracontentattheendofthedocument

Pasting the XML that's generated is probably what you'd need to do. My guess is that you are generating XML with multiple top-level elements; XML requires that you have a single wrapper element at the top level and have all other elements inside it: it's a tree, not a forest.

粘贴生成的XML可能就是您需要做的事情。我的猜测是你用多个顶级元素生成XML; XML要求您在顶层有一个包装元素，并且其中包含所有其他元素：它是树，而不是森林。

My second guess is that you are seeing the error in your Web browser, and it is not being generated by php at all; check your Web server error logs to make sure.

我的第二个猜测是你在Web浏览器中看到错误，并且它根本不是由php生成的;检查您的Web服务器错误日志以确保。

Look at the XML. It should look something like the following:

看看XML。它应该类似于以下内容：

    Here's an item
    Here's another item
    Here's an item with some sub-items
        one
        two
    

The root of the XML document is the block item; it's the item that encloses and surrounds all of the other items.

XML文档的根是块项;它是包围和包围所有其他项目的项目。

If you don't have a root - ie, if the code looks something like this:

如果你没有root - 即，如果代码看起来像这样：

Here's a list of items
But there's no root element

Then you'll get the error you describe.

然后你会得到你描述的错误。

Two possible options. It might be because the rendered XML is not valid. Sometimes, it might be because you don't have enough permissions to access the XML.

两种可能的选择。这可能是因为渲染的XML无效。有时，可能是因为您没有足够的权限来访问XML。
