Hi,
Thanx for the info. But what I want to know is if we don't know the
exact position of the current element like *[1] how do I go
the next or
previous element from the current position (assuming that I don't know
the exact position number).
The position() returns the context position, so in *[position() = 1] it refers
to the context of selecing all child element nodes, i.e. filters out all nodes
whose context position is not 1., i.e. returns the child element; if you have
following::*[1], it selects all the elements that follow the current node, then
filters out all those whose context position is not 1, i.e. again selecting
only the first element that follows the current node.
Position() does *not* return the index of an element; use
count(preceding-sibling::*) + 1 to get the index of an element within it's
siblings. See <http://localhost/tr/xpath/#function-position> and
<http://localhost/tr/xpath/#dt-context-position>.
Can I say something like
*[position()=current()] OR following::*[position()=current()] OR
preceding::*[position()=current()]
current() returns the current node, not a position. What should the above
expression select? The current element or the first following element or the
first preceding element? Is
. | following::*[1] | preceding::*[1]
what you're after?
Will it work ?
Depends what you're after, but basically that will not work, or get you want
you want.
