替代.NET中的XPath id()

<text xmlns:its="http://www.w3.org/2005/11/its" >
 <its:rules version="2.0">
  <its:termRule selector="//term" term="yes" termInfoPointer="id(@def)"/>
 </its:rules>
 <p>We may define <term def="TDPV">discoursal point of view</term>
 as <gloss xml:id="TDPV">the relationship, expressed through discourse
  structure, between the implied author or some other addresser,
  and the fiction.</gloss>
 </p>
</text>

termInfoPointer是一个XPath表达式,它指向< gloss xml：id =“TDPV”>元件.

我使用LINQ-to-XML来选择它.

XElement term = ...;
object value = term.XPathEvaluate("id(@def)");

我得到以下异常：System.NotSupportedException：此XPathNavigator不支持ID.

我找不到这个问题的解决方案所以我试图用其他表达式替换id()：

//*[@xml:id='TDPV'] // works, but I need to use @def

//*[@xml:id=@def]
//*[@xml:id=@def/text()]
//*[@xml:id=self::node()/@def/text()]

但这些都不起作用.

有没有办法实现id()或用另一个表达式替换它？

我更喜欢不涉及用另一个表达式替换id()的解决方案/解决方法,因为这个表达式可能像id(@def)| ID(// * [@ ATTR = “(ID(@abc()))))))”]).

//*[@xml:id = //@def]

如果可能存在不同的def属性,那么您需要提供一个XPath表达式,在您的情况下精确选择所需的def属性：

//*[@xml:id = someExpressionSelectingTheWantedDefAttribute]

基于XSLT的验证：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/">
     <xsl:copy-of select="//*[@xml:id = //@def]"/>
 </xsl:template>
</xsl:stylesheet>

在提供的XML文档上应用此转换时：

<text xmlns:its="http://www.w3.org/2005/11/its" >
 <its:rules version="2.0">
  <its:termRule selector="//term" term="yes" termInfoPointer="id(@def)"/>
 </its:rules>
 <p>We may define <term def="TDPV">discoursal point of view</term>
 as <gloss xml:id="TDPV">the relationship, expressed through discourse
  structure, between the implied author or some other addresser,
  and the fiction.</gloss>
 </p>
</text>

评估XPath表达式,并将此评估的结果(所选元素)复制到输出：

<gloss xmlns:its="http://www.w3.org/2005/11/its" xml:id="TDPV">the relationship, expressed through discourse
  structure, between the implied author or some other addresser,
  and the fiction.</gloss>
