Hi,

I am currently evaluating ATL for pure XML to XML transformations. There are certain aspects which I found cumbersome in ATL and I have listed them here (and compared with XSLT where applies):

1. ATL does not directly input or output XML, and in order to do so, we need to use AM3 and write additional ATL transformations to convert XML to XMI. XSLT works directly with XML.

2. XSLT has ready facility to call external Java methods within the transformation. No idea if ATL has the same, ( read that we have to extend a class to write our custom Java methods)

3. ATL has no graphical tool to define the transformation, and nor has XSLT, so I dont see any clear advantage of ATL over XSLT.

4. Can ATL use XML strings as input and output, and not just File URLs?

Appreciate some guidance on this, and whether I am right in my evaluation.
