XML 验证错误

【问题标题】：Error with XML ValidationXML 验证错误
【发布时间】：2014-09-29 02:08:40
【问题描述】：

我对 XML 还很陌生，我确实很难弄清楚我做错了什么。返回的大多数错误是文档类型不允许此处的元素“跟踪”。如果有人能告诉我我做错了什么，我将不胜感激。 请记住，我已经这样做了不到一个月，提前谢谢。

【问题讨论】：

  • 您能否告诉我们您收到的具体错误，而不是如此笼统地描述它们？
  • 我的主要错误消息是“第 27 行，第 10 列：文档类型不允许元素在此处“跟踪”多行，但我也收到“错误第 156 行，第 9 列：结束标记未完成的“专辑”。

标签： xml validation w3c


【解决方案1】：

是错误的结束标签——听起来你缺少一个 &gt; 字符。查看文件的第 156 行或附近是否有 &lt;/album&gt; 标记，并找出您是如何输入错误的。

关于验证错误：您已声明 

<!ELEMENT disk(#PCDATA)>

您已经告诉它&lt;disk&gt; 应该只包含未标记的文本。你想要的大概是

<!ELEMENT disk(#PCDATA | track)>

甚至可能

<!ELEMENT disk(track)>

如果除&lt;track&gt; 元素之外的唯一内容将格式化空格。

请参阅http://www.w3.org/TR/REC-xml/#sec-mixed-content 和描述 DTD 元素声明的相关部分，或者一个好的 XML DTD 教程。

（您可能需要考虑从 DTD 迁移到 XML Schema，这是描述文档预期结构的一种更强大的方式……除非您需要保持与旧解析器的兼容性。）

【讨论】：

  • 感谢您的帮助，立即清除了我的大部分错误。我重新检查了我的标签，我没有打错或拼错任何一个。我目前正在上 XML 课程，我们实际上将在下周学习 XML Schemas。
  • 如果你得到“错误的结束标签”，解析器会说你输入了错误的东西，并且指向了哪里。再看一遍。这可能不是我建议的具体错误，但文档是错误的，这就是解析器发现错误的地方。
