brilliant - works perfectly. thanks.
(a possible suggestion: for newbies like me, it would be nice to have a
very very basic example right on the front page of the site, which gives
the "import" element and a simple call to "sin" (for example). now that i
see how to do it, it is so simple it seems obvious, but at first i was
confused how to call a "library" from xsl).
thanks again,
andrew

Hi,
I can't work out how to do more complex maths (like logarithms, trig
functions, etc) in XSL. Is it possible? If not, is there any other
tool
I can use in an xml pipeline? Is the only option writing SAX or DOM
code
in some non-dedicated programming language?
(I'm generating plots from XML data via XSL to SVG)
FXSL (a function/template library implementing HOF in XSLT and written
in pure XSLT) implements:
Math functions:

Random number generators:
http://fxsl.sourceforge.net/articles/Random/Casting%20the%20Dice%20with%20FXSL-htm.htm
Higher-order functions, currying/partial application, etc...:

A good example of the math capabilities of FXSL for XSLT 2.0 was
recently provided at:
