Re: XSLT is a pattern-action language. So is AWK. What

Patterns, and the pieces that make up a pattern, do have an underlying grammar, but I can understand that putting various pieces together it may not be obviously clear what is going to happen or what the side effects will be. Also, there is a temptation to want to put EVERYTHING into one glorious pattern and do the match. It can be done, but it takes a lot of care.

Also, to the original statement. Snobol/Spitbol, especially using the construct of a table or line-based patterns, there is never a need for a linear search.

I noticed this similarity in .xslt with the use of the XPath expressions. Very elegant construct. So glad I never had to learn how to parse the DOM model.

Approaching Snobol/Spitbol and .xslt, imo, requires you to have to a different mindset if you are to write elegant programs.

thanks,

I did mean something else, sorry. Lexically, yes, strings need to be closed.

It was a long time ago, but my recollection is that the syntax
allowed any combination of tokens and that combination would mean
something. I wouldn't get a syntax error that the order of tokens was
wrong, or that declarations were missing, or that some concatenations
were nonsensical, or some such.

But recollections are faulty ... it was just what came to mind when
Mike posted.
