Question

I have many functions that takes in one input, e.g.:

<xsl:template name="F">
    <xsl:param name="input"/>
    ... ...
</xsl:template>

To call the function, I need to write:

<xsl:call-template name="F">
    <xsl:with-param name="input" select="'jkljkljkl'"/>
</xsl:call-template>

This seems overly verbose. Since the function has only one parameter, why do we have to write the xsl:with-param node?

Is there a shortcut for calling one-parameter functions?

I want to be able to do something like this:

<xsl:call-template name="F" select-param="'jkljkl'"/>

It’s short and sweet and equally non-ambiguous (since there’s only one parameter). How can we call one-parameter functions in a short and sweet way?

_{Am looking for a solution in both XSLT 1.0 and XSLT 2.0.}

Answer 1

In XSLT 2.0 you can write your own functions by:

• declaring your namespace
• defining the function as a child of the transform root element, using xsl:function declaration.

Example:

<xsl:stylesheet version="2.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:nTan="http://nTan.comr">

  <xsl:function name="nTan:Hello">
   <xsl:param name="string1"/>
    <xsl:value-of select="concat('Hello ',$string1)"/>
  </xsl:function>

  <xsl:template match="/">
    <xsl:value-of select="nTan:Hello('World!')"/>
  </xsl:template>

</xsl:stylesheet>
