(XML) 文档中根元素后面的标记必须格式正确。出发地点：6:2

(XML) The markup in the document following the root element must be well-formed. Start location: 6:2

提问by trtmerlin

Just started out in my XML class and having a bit of trouble finding a solution to my error. I get this error: "The markup in the document following the root element must be well-formed. Start location: 6:2".

刚开始在我的 XML 类中找到解决我的错误的方法有点麻烦。我收到此错误：“文档中根元素后面的标记必须格式正确。起始位置：6:2”。

Any kind of hint or help would be great.

任何形式的提示或帮助都会很棒。

In XML there can be only oneroot element - you have two - headingand song.

在 XML 中只能有一个根元素——你有两个——heading和song.

If you restructure to something like:

如果您重组为以下内容：

<?xml version="1.0" encoding="UTF-8"?>
<song> 
 <heading>
 The Twelve Days of Christmas
 </heading>
 ....
</song>

The error about well-formed XML on the root level should disappear (though there may be other issues).

根级别上有关格式良好的 XML 的错误应该会消失（尽管可能还有其他问题）。

After insuring that the string "strOutput" has a correct XML structure, you can do this:

在确保字符串“strOutput”具有正确的 XML 结构后，您可以执行以下操作：

Matcher junkMatcher = (Pattern.compile("^([\W]+)<")).matcher(strOutput);
strOutput = junkMatcher.replaceFirst("<");
