我有VAST XML，并针对庞大的2.0.1 xsd对其进行了验证。它引发以下错误:-
我的VAST XML:
<VAST xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="2.0"
xsi:noNamespaceSchemaLocation="vast.xsd">
<Ad id="11267375">
<InLine>
<AdSystem version="1.0">Sample vast</AdSystem>
<AdTitle><![CDATA[AD_NFM3122HD.mov]]></AdTitle>
<Description><![CDATA[<p> </p>]]></Description>
<Creatives>
<Creative sequence="1" AdID="" id="11267375">
<Linear>
<Duration>00:00:15</Duration>
</Linear>
</Creative>
</Creatives>
</InLine>
</Ad>
</VAST>
VAST 2.0.1.xsd-https://github.com/chrisdinn/vast/blob/master/lib/vast_2.0.1.xsd
当我从VAST Xml中删除
xsi:noNamespaceSchemaLocation="vast.xsd">时。它运作良好。我是否应该肯定使用此
xsi:noNamespaceSchemaLocation="vast.xsd">。有什么用呢？我必须在其中使用XSD文件名而不是“vast.xsd”吗？
我在Java 1.8上运行，这是我的堆栈跟踪

最佳答案
这是经过修复的XML，可以针对我远程引用的broad.xsd进行有效处理:
<VAST xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="2.0"
xsi:noNamespaceSchemaLocation="https://raw.githubusercontent.com/chrisdinn/vast/master/lib/vast_2.0.1.xsd">
<Ad id="11267375">
<InLine>
<AdSystem version="1.0">Sample vast</AdSystem>
<AdTitle><![CDATA[AD_NFM3122HD.mov]]></AdTitle>
<Description><![CDATA[<p> </p>]]></Description>
<Survey/>
<Error/>
<Impression/>
<Creatives>
<Creative sequence="1" AdID="" id="11267375">
<Linear>
<Duration>00:00:15</Duration>
</Linear>
</Creative>
</Creatives>
</InLine>
</Ad>
</VAST>
我添加了XSD所需的一些元素，但是即使不添加这些元素，您也不应因提示以下错误而收到错误消息
如果您仍然收到上述XML错误，请发表评论，说明产生错误的软件。
更新:仍然无法正常工作？
如果您要在Java代码中指定XSD的位置，
Schema schema = schemaFactory.newSchema(new URL(getSchemaURLString()));
但您希望改用
xsi:noNamespaceSchemaLocation，请尝试删除XSD位置的基于Java的规范:Schema schema = schemaFactory.newSchema();
关于java - 属性 'xsi:noNamespaceSchemaLocation'不允许出现在元素 'VAST'中，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/36717793/
