推荐答案

我将如何处理这个问题与@Kirill Polishchuk 所做的相同 (+1 btw)，即仅覆盖节点的身份转换需要改变.

How I would approach this question is the same way that @Kirill Polishchuk did (+1 btw) and that is to override the identity transform only for the node that needs to change.

但是，在您的问题中，您表示我只想使用身份模板.".如果确实如此并且您只想要一个模板，您可以这样做:

However, in your question you stated "I would like to use identity template, only.". If this is truly the case and you only want one template, you can do it like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="node()|@*">
    <xsl:choose>
      <xsl:when test="current()[name()='RequestQueue'][ancestor::SORRegion[@name = 'default']]">
        <xsl:copy>
          <xsl:text>DEFAULT.REQUEST</xsl:text>
        </xsl:copy>
      </xsl:when>
      <xsl:otherwise>
        <xsl:copy>
          <xsl:apply-templates select="node()|@*"/>
        </xsl:copy>        
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

</xsl:stylesheet>

我很想知道为什么您只想使用身份转换模板.如果您最终需要修改的不仅仅是 RequestQueue，它会很快变得丑陋.

I would be curious to know though why you would want to use the identity transform template only. If you end up needing to modify more than just RequestQueue, it's going to get ugly fast.
