Re: [xsl] Are there any free, fully-compliant XSLT/XPath 3.0 processors?

eXist is working towards full XPath and XQuery 3.0 compliance and we
already implement most of this. eXist is open source under LGPL 2.1

Whilst eXist can run as a standalone database you can also use it as
an embeddable library in your own Java applications and it will allow
you to execute XPath 3, XQuery 3 and XSLT 2.

Hello Roger,

Yes I see your situation ... when non techies are confronted by
choosing between XYZ technology and one has a cost and another
apparently has no cost ... they classically drift towards the zero
cost solution. I sometimes wonder how much 'impl' detail to give to
people making cost decisions ... e.g. there is always a cost
associated with adopting any software.

I believe what your challenge is to present the true costs of both
approaches; remember to include major risks as well (what if Oracle
wanted to try and kill off Java ???). as the positives (xslt has a
rich history in document manipulation)(extensible markup is not going
away). Software is a bit different then buying some part of a piece of
machinery, it can enable cost optimisations but it can also present
new opportunities which create new revenue generating scenarios ... I
sometimes think the most successful software is when it was brought in
to do a job (does it well), and also enables a range of future
positive scenarios.

While having a 'free' implementation may seem like a 'silver bullet'
solution to your conundrum its not ... you have enough 'free' out
there IMO to tell your non techies the story.

A software license of a few k to a medium sized company represents a
very minor cost (Compared to the humans running/managing the software)
.. .its easy to demonstrate how the license pays for itself, getting
over that first unit of currency is the issue.

That is a wonderful argument Liam. When I tell my operational people this 
and then tell them, "Oh, you want to distribute this capability to the xx 
thousands of people in the field. Okay, I'll implement it using XSLT/XPath 
and you'll have to buy a license for them and that will cost many yy 
thousands of dollars." They simply respond, "No, do not use XSLT/XPath. 
Implement the capability in Java and distribute it for free to the people in 
the field."

    BaseX is free and as an XQuery 3.0 implementation
    it is also an XPath 3.0 implementation.

Thanks for notifying me of this Dimitre. I took a look at it. It appears to 
be a database supporting XPath and XQuery queries. That won't help me build 
fieldable applications. Please correct me if I am wrong.

Jim, they are non-techies. They don't care about XML or XSLT or XPath. They 
are people with real, operational needs. Particular technologies is of no 
interest to them. But telling them that by using XSLT/XPath they will have 
to purchase licenses costing many yy thousands of dollars -- that gets their 
attention. And immediate dismissal of XSLT/XPath.
