XSLScript is part of Hiawatha web-server, but XSLScript also can be used stand-alone. + +To execute XSLScript script: + +xsls some.xml some.xsls +The XSLScript script (some.xsls) gets compiled into corresponding XSLT stylesheet and then generated XSLT stylesheet is applied to the file some.xml (no temporary .xsl file is created, this all happens in the memory). The actual XSLT tranformation is performed by SAXON. There is 1-1 lines mapping between XSLScript script and generated XSLT ( this means if some XSLScript construction starts on line 5, the corresponding XSLT construction will also start on the same line 5. ) + +To generate the XSLT stylesheet out of XSLScript script: + +xslsdump some.xsls +or + +xslsdump-indent some.xsls +if you want a nice looking indentation. + +Why XSLScript ? + +XSLT syntax is not for human beings. + +One can write complex XSLT code in XSLScript and then generate the 100% XSLT stylesheet.

If this is not enough, please note that XSLScript distribution contains more than 10 examples of XSLScript code. Those examples are XSLT stylesheets from Michael Kay's XSLT Programming Reference (available for download from Wrox website) rewritten in XSLScript. This results in XSLScript examples being educational and covering almost every XSLT (XSLScript) command. + +Rules + +There are top-level XSLScript constructions and instructions. (exactly like it is in XSLT). Instructions could be separated from the content with <% and %> ( optional ). +Instruction has body and header. Body is separated from header with { } +'match', 'select', 'test' and 'name' are not written (but also could be written in some exotic cases.) +Symbols ', ", {, are special. Use \{ e t.c. if you need those special symbols in tne content of your stylesheet. +xsl:apply-templates, !! and xsl:number should end with ";" +Syntax of apply-templates is extremely close to the syntax of call-template. +There are few shortcuts: +You can use !{xpath-expression} for +X:value-of select="xpath-expression"; +!! for X:apply-templates +!foo() for X:call-template name="foo" +X:var for X:variable +There is 'comma' shortcut. It exists for X:stylesheet (see date.xsls for example of XSLT-engine independent java binding).
