RE:  simulating for with foreach
You're not making your requirements very clear. 

If you have the sequence of positions as input (in XSLT 1.0 this would have
to be in a node-set, e.g.

<xsl:variable name="positions">
  <p>1</p>
  <p>5</p>
  <p>6</p>
</xsl:variable>

then you can process the nodes at those positions using

<xsl:variable name="nodes" select="nodes"/>

<xsl:for-each select="$positions/p">
  <xsl:variable name="pos" select="number(.)"/>
  <xsl:apply-templates select="$nodes/node[$pos]"/>
</xsl:for-each>
