RelaxNG枚举的元素名称 [英] RelaxNG enumerated element names

问题描述

如果我的元素名称必须看起来像这样:

If I have element names that must look like this:

<myElem>
  <subElem_n/>
  <subElem_n+1/>
  <subElem_n+2/>
</myElem>

其中'n'= 0;

我将如何实施RelaxNG?

How would I enforce this is RelaxNG?

棘手的部分是动态生成的元素名称.

The tricky part is the dynamically generated element names.

推荐答案

关于XML示例文件:

您提供的XML格式不正确. XML名称中不允许+. 请参见此处，看看PrefixedName和UnprefixedName具有精确的语法.

The XML you provide is not well formed. The + is not allowed in XML names. See here, have a look at PrefixedName and UnprefixedName to have precise syntax.

关于您的验证案例:

据我所知，您不能使用Relax NG在元素名称上添加动态生成的验证规则.

As far as I know, you can't add dynamically generated validation rules on element names with Relax NG.

检查这种结构的唯一方法是使用ISO Schematron或即将带有xs:assert元素的XML Schema 1.1重新命令.

The only way to check this kind of structure is to use either ISO Schematron or the upcoming XML Schema 1.1 recommandation with the xs:assert element.

这两种解决方案都使用XPath，您可以使用local-name()函数检查名称.

Those two solutions use XPath and you can check the names with the local-name() function.

还有一件事

请注意，拥有这种结构并不总是被视为一种好习惯，您也可以考虑采用这种结构:

Be aware that it's not always considered a good practice to have such structure, you can also consider this kind :

<myElem>
    <subElem rank="1"/>
    <subElem rank="2"/>
    <subElem rank="3"/>
    ...
</myElem>
