[xsl] applying templates out of a for-each

[Detlef Heyn <detlef.heyn@xxxxxxxxx>]

Hi my dear experts


I would appreciate your help with a problem i have.

From a xml file i read the content of an element wich i interpret in 
many possible ways for it's a config file for my stylesheet.

This info i give to a template as a parameter simply called "input".

One way i interpret the value is as an element name wich content i want 
to select.

This works fine until i use the following code:

==================================================
<config-input>show_element:Elementname</config-input>
=========================
<xsl:template name="select">
 <xsl:param name="input"/>
 <xsl:choose>
  ...
  <!-- show element -->
  <xsl:when test="contains($input,'show_element:')">

   <xsl:apply-templates select="//node()[name() = 
substring-after($input,':')]" mode="pure"/>

  </xsl:when>
   ...
 </xsl:choose>
</xsl:template>
=========================

but if i want to apply more than one element-content with the help of a 
for-each over the readed config-input (wich im tokenizing to seperate 
the certain element names) i get this error:

"F[Saxon-B 9.0.0.6]Cannot select a node here: the context item is an 
atomic value
URL: http://www.w3.org/TR/xpath20/#ERRXPTY0020";

==================================================
<config-input>show_element:Elementname1 Elementname2</config-input>
=========================
<xsl:template name="select">
 <xsl:param name="input"/>
 <xsl:choose>
  ...
  <!-- show element -->
  <xsl:when test="contains($input,'show_element:')">
   <xsl:for-each select="tokenize(substring-after($input,':'),' ')">
    <xsl:variable name="temp_name" select="string(.)"/>
    <xsl:apply-templates select="//node()[name() = $temp_name]" 
mode="pure"/>
   </xsl:for-each>
  </xsl:when>
   ...
 </xsl:choose>
</xsl:template>
=========================

I understand that Saxon has a problem with applying templates inside of 
a for-each-loop wich is all about selecting atomic values (strings in 
this case)


* Do I guess right or don't i catch the real cause?

* And how, if possible, do i get it work as intented?
(I'm afraid I've just overseen a simple thing)



Thanks a lot for your help in advance.

have a good time
