XML错误:文档末尾的额外内容

Question

这是XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<document>
<name>Sample Document</name>
<type>document</type>
<url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;wordcount3=0</url>
</document>

<document>
<name>Sample</name>
<type>document</type>
<url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;</url>
</document>

我打开它时说: This page contains the following errors: error on line 8 at column 1: Extra content at the end of the document

但只有这样:

<document>
<name>Sample</name>
<type>document</type>
<url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;</url>
</document>

没关系.为什么有两个这样说呢？

Answer 1

您需要一个根节点

<?xml version="1.0" encoding="ISO-8859-1"?>    
<documents>
    <document>
        <name>Sample Document</name>
        <type>document</type>
        <url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;wordcount3=0</url>
    </document>

    <document>
        <name>Sample</name>
        <type>document</type>
        <url>http://nsc-component.webs.com/Office/Editor/new-doc.html?docname=New+Document&amp;titletype=Title&amp;fontsize=9&amp;fontface=Arial&amp;spacing=1.0&amp;text=&amp;</url>
    </document>
</documents>

Answer 2

我发现如果文档为空也会生成此错误。在这种情况下，这也是因为没有根元素 - 但错误消息“额外内容和文档结尾”在这种情况下会产生误导。
