Sofar I have always used XSLT to transform from XML to XML.

I am working on a new project where the input file is in a text flat
file:

account_no,123456,subscr_no,654321

Is it possible to read such a file with XSLT and transform the first
field until the comma into an XML element and put the second field as
its value and etc?

Is this a reliable way to do that?

Many Thanks,
Houman
