but if i want to apply more than one element-content with the help

Correct, because you are not in a node tree when you are acting on
the tokens from a string.
==================================================
<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)
It is not Saxon's problem at all! It is your problem for trying to
use "/" when there is no current node.

You have missed the real cause and blamed software for your own
stylesheet problem.
* And how, if possible, do i get it work as intented?
(I'm afraid I've just overseen a simple thing)
Put the root node you want to use into a variable and then address off if it:
<xsl:variable name="top" select="/"/>
<xsl:for-each select="tokenize(substring-after($input,':'),' ')">
<xsl:variable name="temp_name" select="string(.)"/>
<xsl:apply-templates select="$top//node()[name() = $temp_name]"
mode="pure"/>
</xsl:for-each>
BTW, your use of "name()=$temp_name" is not sensitive to namespaces,
which may or may not be important to you in the long run. Look up
the use of node-name() and functions returning QName values.
I hope this helps.
