XSLT Pass current context in call-template

Question

In XSLT 1.0, what is the shortest/cleanest/recommended way to pass the current context node to a called template and have that node become the context node inside the called template?

It would be nice (it would, right?) if a template with no xsl:param and called by an empty call-template would simply pick up the caller's context node, but the best I can think of is this:

    <xsl:call-template name="sub">         <xsl:with-param name="context" select="." />      </xsl:call-template> 

with

<xsl:template name="sub">     <xsl:param name="context" />     <xsl:for-each select="$context">      </xsl:for-each> </xsl:template> 

Answer 1

It would be nice (it would, right?) if a template with no xsl:param and called by an empty call-template would simply pick up the caller's context node.

This is exactly how xsl:call-template is defined in the W3C XSLT 1.0 (and 2.0) specification, and implemented by any compliant XSLT processor.

Here is a small example:

<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">  <xsl:output method="text"/>   <xsl:template match="a">   <xsl:call-template name="currentName"/>  </xsl:template>   <xsl:template name="currentName">   Name: <xsl:value-of select="name(.)"/>  </xsl:template> </xsl:stylesheet> 

When this transformation is applied on the following XML document:

<t>  <a/> </t> 

the wanted, correct result is produced:

  Name: a

Just otherway of explaining what Dimitre said.

When you call a template from a node, you are already there in that node,

example:

assume this code:

<xsl:template match="MyElement">     <xsl:call-template name="XYZ"/> </xsl:template>  <xsl:template name="XYZ>     <xsl:value-of select="."/> </xsl> 

The above code is as good as writing:

<xsl:template match="MyElement">     <xsl:value-of select="."/> </xsl:template> 

You can use for-each loop in the called template as well. :)

But just be sure where you exactly are ..
