thank you very much.

Unless I completely mis-understand DOM Joe, XML-INTO is not a DOM parser. The only thing you can tell it to do (via the path=... option in the %XML BIF) is where to start in the document. But that is a long way from the DOM notion of random access. path=... will let me specify to skip a chunk at the beginning before (for example) the section detailing all the invoices - but it won't let me specify to start at invoice X which is how I think of DOM.

I do think that XML-INTO is a lot better than folks here have given it credit for - it is very "RPG-like" and works very well. It is not perfect by a long way - but for straightforward schemas it is wayyyyyyyy easier than any SAX approach.

I wrote a series of articles for MC Press on the topic the first one is here:
