[xquery-talk] FLWOR in XSLT 2.0?

[Evan Lenz]

It's the XPath subset of XQuery, which supports "for" expressions but not full FLWOR statements, to the sometime consternation of XSLT developers (e.g. having to switch to <xsl:for-each> and <xsl:variable> when all you really wanted was "let").

Funny, I always thought the FLWOR was an XQuery only thing...

<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:b="books">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:template match="/">
  <xsl:sequence select=
  "(for $m in max(for $n in distinct-values(/*/b:book/(b:author |
b:editor)
                                           /b:name/concat(b:fname, '|',
b:lname)),
                  $cnt in count(/*/b:book/(b:author | b:editor)
                                /b:name[$n eq concat(b:fname, '|',
b:lname) ])

...

(Looks quite horrible to me, like someone couldn't decide between XQuery
and XSLT.. :-/)
