simulating for with foreach

Thanks Mike, Thanks David,
to clarify my request, suppose I don't have needed sequence of nodes
anywhere, and want to access every 4 elements: 1, 5, 9, ... to the
end. Do I have to use <xsl:if test="position() mod 4 = 1", or there is
a more flexible way?

If you only want to iterate over elements, just select elements not text
nodes, then position() will give the position in the sequence of
selected items.

<xsl:for-each seelct="node[position() mod 2 =1]"

does what you want, I think.
