Re: [xsl] preceding-sibling reversed ?

you just want <xsl:value-of select="preceding-sibling::div[@class = 'slide'][1]/@id to get the nearest previous sibling with slide class. what you have <xsl:value-of select="preceding-sibling::div[@class = 'slide' and position() = 1]/@id selects the nearest sibling if it has a slide class and nothing otherwise. If all your div elements have a class="silde" then these are equivalent, otherwise not. in the step preceding-sibling::div you are in a reverse axis, so all teh selected nodes are numbered in reverse document order. so your filter [@class = 'slide' and position() = 1] selects all (at most one) of those nodes that satisify the stated condition. however if you do it with two filters first preceding-sibling::div[@class = 'slide'] now the resulting node set is renumbered (still in reverse order, as you are still in the same step) so now the [1] or equivalenetly [position() = 1] selcts the first of _these_ elements, ie the first element (looking back) with class slide.
