Such a preprocessing transformation step would be very useful.
In order to do that entirely in BaseX, I load the data twice.
Once in a temporary collection (that may be an in memory collection), from
where I perform the transformations.
Then I load the transformed data in the final collection.
Hello Etanchaud,
Such a preprocessing transformation step would be very useful.
This means that BaseX does not have such a tranformation step at present.
To achieve this in the current BaseX version, what would be the efficient
method?
I have now tried creating database by importing the XML
If you use XQuery update facility,
I agree that adding a attribute on every element will lead to a huge pending
update list that could fill your ram.
I suggest to process your data in smaller partitions.
For each partition,
You could transform your data with a recursive function and store it in
Hi Mallika,
Then
inserting attribute on all child nodes using an xquery recursive function.
You could try to use XQuery Update and a simple loop:
for $a in db:open('your-database')//*
return insert node attribute x { 'yz' } into $a
I would be interested if such a call can be evaluated
Malika,
Is this attribute a kind of annotation or index ?
If you need to annotate/index your data,
I suggest not to mix source data and annotations,
But to create a annotation/indexation collection afterwards.
Maybe node-pre functions could help you ?
You could create a separate collection
