Erwin,
Your problem has been a theme lately. (I hope you've been reading.)
At 12:06 PM 9/11/2003, you wrote:
I have a node-set of entries that all have different values for their text
attribute.
An entry looks like this <entry text="aaa"/>.
This node set is build through muenchian grouping and assigned to a
variable called 'legend'.
Now, for some current entry, I need to know the position of an entry with
the same text attribute
within the $legend node-set.
eg. $legend contains entries <entry text="aaa"/>, <entry text="bbb"/>
<entry text="ccc"/>.
for some entry <entry text="ccc"/> I need to get the number 3.
As a result tree fragment (constructed by the processor and bound to a
variable), $legend can't be inspected this way, so if you can't find a way
to see that a <entry text="ccc"/> node in your source *will be* the third
in your order, you're stuck.
If $legend is a true node-set, however, you can traverse it in the usual
way, e.g. ask
count($legend/entry[(_at_)text=current()/@text]/preceding-sibling::*)+1.
To make $legend a true node set, use XSLT 2.0 (the draft is partially
implemented in the current version of Saxon), or, in XSLT 1.0, your
friendly vendor's node-set() extension function.
Cheers,
Wendell
