Hi Rudolf, > ok, my original data are: > > <table> > <cols> > <col name="persno" width="..." align=".." grid="..." .....> > <col name="name" width="..." align=".." grid="..." .....> > <col name="address" width="..." align=".." grid="..." .....> > </cols> > <rows> > <row memo=".."> > <cell>123</cell> > <cell>John Smith</cell> > <cell>1st avenue, 1040 Boston</cell> > </row> > ... > </rows> > </table> > > When I format this xml I want: > <xsl:for-each select="table/rows/row"> > <TR><TD> > <xsl:value-of select="give me the cell cell > which position is the same [position()= > as the position of element col count(../../cols/col > which attribute is name"/> [@name='name']/preceding-sibling::col)+1] > </TD> > </TR> > </xsl:for-each> in other words: find the correct col element, count its predecessors and compare this number to the current position of the cell. cell[position()=count(../../cols/col[@name='name']/preceding-sibling::col)+1] or shorter, by omitting the comparison with position() cell[count(../../cols/col[@name='name']/preceding-sibling::col)+1] > Thats all what I want.

Because you can write in the same manner following::element[position()=5] following-sibling::element[position()=5] descendant::element[position()=5] and get probably three different element nodes. An element has no position by itself, only within a node list. Hope that helps, Oliver /-------------------------------------------------------------------\ | ob|do Dipl.Inf.
