Hi there,


I have been using templates where I pass in a node set and the template returns a single value.

Just wondering if it is possible to pass a parameter which contains a node set to a template. And this template does some processing to this node set and generates another node set.

for eg. my node set is such
<parent>
  <name>john</name>
  <amount>50</amount>
<parent>

so I call the template in my xslt
<xsl:variable name="result_node">
  <xsl:call-template name="process_parent">
    <xsl:param name="myNode" select=parent[1]/>
  </xsl:call-template>
</xsl:variable>

the result_node should hopefully be
<person>
  <name>john</name>
  <balance>positive</balance>
</person>

thanks

Your "node set" seems actually to be a tree rooted at a single node (the children don't count, they come with it automatically). So the simplest way to "pass it to a template" is to call apply-templates on it.

You actually seem to be doing a standard transformation on this tree, so you want an identity template that copies things unchanged:

<xsl:template match="*">
  <xsl:copy>
    <xsl:apply-templates/>
  </xsl:copy>
</xsl:template>

and another one that changes amount into balance:

<xsl:template match="amount[. &gt; 0]">
  <balance>positive</balance>
</xsl:template>

<xsl:template match="amount[. = 0]">
  <balance>zero</balance>
</xsl:template>

<xsl:template match="amount[. &lt; 0]">
  <balance>overdrawn</balance>
</xsl:template>
