Re: [xsl] xsl:function

[Abel Braaksma <abel.online@xxxxxxxxx>]

XSLT is a language that can be run in a number of ways (just like any 
other language). If you want to run it from inside a browser, you can 
indeed do that, but you are stuck with XSLT 1.0 for the near foreseeable 
future.

However, browser based transformations are not easy and you have to know 
quite a bit of what is going on under the hood which makes it far from 
ideal for beginners (let alone the differences between browsers: subtle, 
but important).

If you want to learn XSLT, I recommend downloading Saxon. Use Saxon.NET 
if you want just a simple executable that you can run from within your 
favorite Integrated Development Environment. If you use Eclipse as IDE, 
I think it is more likely that Saxon for Java suites you better.

If for one reason or the other, you are stuck with using client side 
transformations, you can create non-portable functions using 
msxml:script. Search google for examples, but remember: it will only 
work in IE and it is not a recommended practice (IE7 has parsing scripts 
in XSLT off by default).
