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.
A great improvement would be to provide the import step with an iteration’s xpath and a xquery transformation function, So the transformations are loaded instead (Zorba and Saxon-enterprise have a streaming mode like this).

Hello,
We have a requirement to create a database by importing a large XML file. During this process, we also want to insert a particular attribute on all child nodes. Which is the efficient method to do the same? The file size is nearly 1GB.
Thanks in advance, Mallika Jacob
