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).

Objet : [basex-talk] Import a large XML file and add an attribute on all children

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
