Re: [xsl] XSLT Hello World - outreach

Hi,

I have been wondering how to introduce what Rich has just mentioned
... XSLT's accessibility to (so-called) "non-programmers".

I have had similar success. Indeed, I have gone (considerably) beyond
what he describes -- I give them templates. They usually say "how
curious", and then start using them -- training their brains in tree
traversals and learning about context while doing so.

A big part of the reason why the question of promoting XSLT is complex
is that one of our natural constituencies may not be in the places
where "experts" in computing or programming are to be found.

To be sure, they tend to be active and inquisitive people, and not
inclined to think of their machines (or the priests who attend their
needs) as masters to be humored. And they may not be as interested in
programming as in their data and what they want to do with it.

These people can often do very well with XSLT, and not only on a
casual basis, especially if they have an accessible expert and/or
community to help when they get stuck. Then they become "experts" and
everyone thinks they are "programmers".

Organizational culture may make this difficult, however, Putting these
people in a position where they can help themselves doesn't seem to be
something that can be done from outside -- organizations have immune
systems to prevent this sort of thing, which can be disruptive.

Cheers, Wendell

I've never got anybody to believe XSLT was easy; I have got people to

XSLT is along that axis. "Here are things we can do reliably that are
much harder any other way".
Remarkably, I *have* gotten people to believe XSLT is easy -- and those have 
almost always been people who are not traditional programmers!

Of course, these folks aren't doing complex transformations. But they are 
people, who for one reason or another, have been given XML to deal with, and 
just want to produce a nice HTML page or convert to a different XML format. 
I've shown these folks just three elements, wrapped in a single <xsl:template 
match="/">:

1. xsl:value-of
2. xsl:choose
3. xsl:for-each

and only enough XPath to understand something like "//book[@author='Bob']".

This is not "Hello World" -- which I have always considered a useless 
exercise for anything other than testing a compile/build environment. But it 
is what I call an 80-20 solution: 80% of what you want, for 20% of the effort.

The people I've shown this to have done a lot of great things with just these 
three elements, and some have gone on to learn a lot more of XSLT. Funny that 
the non-programmers have been easier to convert than the hot-shot hackers. ;-)
