Add sugar to XSLT
A simple template that transforms XSLT with a slight addition of syntactic sugar to regular XSLT. Instead of the description, I give a small example in which all new constructions are used.
After converting this code, we get the usual XSLT:

PS: Script to transform your Sugar XSLT:
#!/bin/sh cp $1 $1.bak xsltproc -o $1 xslsugar.xslt $1 On Windows, this can be done through: msxsl.exe -o template.xslt template.xslt xslsugar.xslt (did not try)PPS: If you want to use an existing xmlns: xsl, which is not correct, but convenient, then simply replace the
xmlns:x="xslt-sugar" namespace in xslsugar.xslt with xmlns:x="http://www.w3.org/1999/XSL/Transform" and remove x:* from the empty template: <xsl:template match="@x:*"/> , as a result you can write without an additional namespace: <p xsl:each="item">For the next version, and further development, look at code.google.com/p/xslt-sugar
