使用RelaxNG-schema验证XML的问题

时间:2017-11-25 16:28:30

标签: xml validation relaxng xmlschemaset

我无法根据我的RelaxNG架构验证我的XML。我有点新的放松,所以请原谅我,如果错误很明显。

Jing在验证时会产生三种错误:

错误1:“元素”文章“此处不允许;预期元素”章节“”

错误2:“元素”文章“此处不允许;期望元素结束标记”

错误2“元素”章节“此处不允许;期望元素结束标记”

1 个答案:

答案 0 :(得分:1)

您的XML似乎与架构不匹配,因为:

  1. 元素的顺序被定义为“书”,“文章”,“章节” - 你有无序的元素。

  2. 我不熟悉RelaxNG-schema,但在传统的XSD架构中,必须定义元素出现次数(默认min = 1 max = 1)。看起来您的架构只允许一本书,然后是一篇文章,然后是一章。

  3. 所以,

      

    错误1:“元素”文章“此处不允许;预期元素”章节“”

    出现

    是因为首先有<article>,但预计会<chapter>

    Error 2: "element "article" not allowed here; expected the element end-tag"
    Error 2 "element "chapter" not allowed here; expected the element end-tag"
    

    出现是因为在第一本书和第一篇文章之后有很多文章,章节和书籍......

    建议:

    1. 使用无序元素 - 使用XML选择书,文章,章节
    2. 将该选项的出现定义为“many”
    3. 我知道如何在XSD中做到这一点,但对于RelaxNG来说,这取决于你......
