That almost works. It appears I can pass the variable by executing the ‘set bindings’ command ahead of the query. But if I use the variable in a test like this:

declare variable $ext_variable as xs:string external;

for $div in collection(‘waldo’)//div[@xml:id=$ext_variable]

I get nothing. And yet I’ve been able to return the variable itself from the module and check its type, and use it in a let assignment. So I can see that the module is receiving the value I send, it just isn’t matching for some reason.

Hi Bryan,

Could http://docs.basex.org/wiki/Options#BINDINGSgive you a solution ?

Best regards,

Objet : [basex-talk] sending variables to xquery module via client api (python)

Hi—

Hoping someone can help me with this. I’m trying to write a python script that calls an xquery module in the database. It seems to be pretty easy to use a line such as:

session.execute(“run gettext.xqm”)

and get back the response I want. What I want to do is pass a bound variable to the module. The client api has a provision to bind a variable to a query object, but I’m not making a query object. I’m simply executing the stored query. I don’t find anything in the documentation to suggest that a variable can be added to the run command this way.
