Hi Marco,
You may be surprised (or not) that I thought about a similar
functionality. Indeed I wondered if we could allow function items as
input for client:query and xquery:evaluate.
I like your idea of providing an explicit serialization function. For
several reasons, we cannot guarantee that
Hi Mansi,

Hi James,
Beforehand: Please send your mails to
basex-talk@mailman.uni-konstanz.de; otherwise, they won't be directed
to everyone.
Currently, there is no way to prevent the unescaping the entities (the
XML and XQuery specifications do not foresee this). One way to enforce
the escaping of certain
Hi Carl,
In the BaseX query parser, tokenization and parsing is a joint
operation. in the past, we thought about splitting these steps, as the
tokens could also be used in the GUI to provide better highlighting.
However, we'd probably need some more coders interested in making that
happen..
One more thing we have to be aware of: In XQuery, we have lots of
different function items. I wonder if we should support all of these?
declare function local:f() { 123 };
inspect:serialize(map {}),
inspect:serialize(local:f#0),
inspect:serialize(substring#2),
This would need a lot of details, so bear with me below:
Briefly my XML files look like:
A name=
B name=
C name=
D name=
E name=/
A can contain B, C or D and B, C or D can contain E. We have 1000s
(currently 3000 in my test data set) of such xml files, of
Hi Mansi,
Here you have a natural partition of your data : the files you ingested.
So my first suggestion would be to query your data on a file basis:
for $doc in db:open(‘your_collection_name’)
let $file-name := db:path($doc)
return
file:write(
$file-name,
names
Interesting idea, I thought of using db partition, but didn't pursue it
further, mainly due to below thought process.
Currently, I am ingesting ~3000 xml files, storing ~50 xml files per db,
which would be growing quickly. So, below approach would lead to ~3000 more
files (which would be
Hi Mansi --
Just out of habitual paranoia about the performance of *// in XPath, I
might try replacing /A/*//E/@name/string() with
E[ancestor::A[not(parent::*)]/@name and not worry about stringifying
the resulting sequence of attribute nodes until the next step,
whatever that might be. It might
The solution depends on the usage you will have of your extraction.
May I ask you what is your extraction for ?
Best regards,

To complement this: In a straightforward implementation, the following query…
declare function local:f() { 123 };
inspect:serialize(map {}),
inspect:serialize(local:f#0),
inspect:serialize(substring#2),
inspect:serialize(function() {1})
…would yield the following result:
map { }
I would be doing tons of post processing. I never use UI. I either use REST
thru cURL or command line.
I would basically need data in below format:

I am trying to whitelist picking up values for only
starts-with(@name,pqr). where pqr is a list of 150 odd values.

Hi Mansi --
If you use
for x in E/@name[starts-with(.,'pqr')] return
(tokenize(base-uri($x),'/')[last()],string($x))
for each of the 150-odd values (you may want to generate the query :)
it will more likely work. It's not just the size of the database,
it's the size of the result, too; keeping
In some case, it's even not possible because the optimizer creates new
expressions that have no counterpart in the original XQuery language
Do you mean they invoke internal BaseX functions? Also to help me
understand what BaseX optimization involves:
If these serializations are post
