Hi RonnyI use BaseX to do some transformatins over Pyton binding.
In case I test it in GUI, I have in my current collection one source document.
When I process it remtoely, I pass the data as string and convert it into xml document.
So in my XQuery code I have this:
(:
let $xml := collection()[1]
:)
let $xml := util:eval($xmlString)
The later is used in production and is converting incoming string into xml doc.

Hello,
I want to query a BaseX XML Database via Python (BaseXClient.py).
Therefore I write a XQuery script, which executes a FLOWR expression
combined with a few self-written functions. A bunch of options, which
are generated within my Python script, have to externally bind to this
query.
For convenience it would be appropriate to have optional external
variables which I do not have necessarily to bind, but which will have
default values specified in the XQuery script. Is there a possibility to
do this?
I thought about an alternative, that is to declare the options with the
help of a XML snippet. But then I could not figure out how to bind this
snippet as a node instead of a string, because XQuery itself does not
have a function to convert a String containing a XML document to a node.
Of course I could create before each request a new options document in
the database, but this seems to be a bit unhandy.
All in all I have the impression, that those are quite easy problems,
but for some reason I could not find any solution on the web, so I were
glad about reading a solution to one of those problems.
All the best,
Ronny
