Hi Willaim

forgive me for my newbie question..
i was not very much successful in writing the xpath expression to
get to the childelement1.
could you please help me getting the expression.
i tries weird expressions like
preceding-sibling[parent::childelement]..
I know i am wrong at the expression.. but my idea was to get the
preceding sibling of the parent of childelement
any suggestions in this regard is appreciated

<xsl:value-of select="parent::childelement/preceding-sibling::childelement1/text()"/>

or as Markus suggested..
<xsl:value-of select="../../childelement1/text()"/>

Hello Cutlass

when node context is <name/>

use parent::  to get to childelement and/or combine with
preceding:: in your
select statement to get to childelement1

well, if they are unneccesary u dont need to use them ? any use
of them will
cause an overhead, no matter how slight.

use parent::  to get to childelement and/or combine with
preceding:: in your
select statement to get to childelement1

if u only need to go up to the parent, then this statement will
take up more
processing time which increases with the overall size of your xml
doc.
