XSL element apply-imports

Overriding Template Rules

<apply-imports>
Model: EMPTY
</apply-imports>

A template rule that is being used to override a template rule in an imported stylesheet (see conflict) can use the xsl:apply-imports element to invoke the overridden template rule.

At any point in the processing of a stylesheet, there is a current template rule. Whenever a template rule is chosen by matching a pattern, the template rule becomes the current template rule for the instantiation of the rule's template. When an xsl:for-each element is instantiated, the current template rule becomes null for the instantiation of the content of the xsl:for-each element.

xsl:apply-imports processes the current node using only template rules that were imported into the stylesheet element containing the current template rule; the node is processed in the current template rule's mode. It is an error if xsl:apply-imports is instantiated when the current template rule is null.

For example, suppose the stylesheet doc.xsl contains a template rule for example elements:

<xsl:template match="example">
  <pre><xsl:apply-templates/></pre>
</xsl:template>

Another stylesheet could import doc.xsl and modify the treatment of example elements as follows:

<xsl:import href="doc.xsl"/>

<xsl:template match="example">
  <div style="border: solid red">
     <xsl:apply-imports/>
  </div>
</xsl:template>

The combined effect would be to transform an example into an element of the form:

<div style="border: solid red"><pre>...</pre></div>
