Hi,
I’m testing BaseX and I have a very short question about XQuery Update Facility. If I try in other XQuery processor like Saxon a simple query that add a ‘id’ in XML, like this:
xquery version "1.0";
declare default element namespace "http://www.w3.org/1999/xhtml";
let $sourcedoc := fn:doc("MOST.xhtml")
return
for $ancora at $gatto in $sourcedoc//*[@class="testo"]
return
if (not($ancora/@id)) then
insert node attribute id {concat("testo",$gatto)} into $ancora
else()Saxon run the Query and change the original file, “MOST.xhtml”. If I try the same query in XBase on Ubuntu, I see in the log XBase find the tag to add the id, but the original file is not changed. What I’m missing?
Thank you
Fabrizio

Hi Fabrizio,
By default, updates will not be written back to documents in the file system. However, this feature can be activated with the -u
command-line option [1].
Hope this helps,
Christian

Written for BaseX 8.1. BaseX may have changed since: please check the current documentation.
