Hi,
So I’m looking for a xquery function that I would have thought would be quite
common, but searching has turned up a blank (partly because the search terms I
can think of are too generic). Say if you have the following documents:
<book> <title>Moby Dick</title> <chapter>Chapter 1 title</chapter>
<chapter>Chapter 2 title</chapter></book>
<book> <title>War of the Worlds</title> <chapter>Chapter 1
title</chapter> <chapter>Chapter 2 title</chapter> <chapter>Chapter 3
title</chapter></book>
You can import all of the documents into corb using the following get-uris.xqy:
xquery version "1.0-ml";let $uris := cts:uris('', 'document')return
(count($uris), $uris)
I would then like to add another element to each book document that gives the
number of chapters in each of the books, i.e., the resulting documents should
be like this:
<book> <title>Moby Dick</title> <chapter>Chapter 1 title</chapter>
<chapter>Chapter 2 title</chapter> <total chapters>2</total
chapters></book>
<book> <title>War of the Worlds</title> <chapter>Chapter 1
title</chapter> <chapter>Chapter 2 title</chapter> <chapter>Chapter 3
title</chapter> <total chapters>3</total chapters>
</book>
What xquery would one use in the transform-docs.xqy to do this? Inserting
another element is easy (xdmp:node-insert-child) but actually counting up the
number of a particular element for each document is what I’m not sure of. Any
insight appreciated.
Thanks,
Mark
