Subject: RE: [xsl] Challenge: do better than my implementation of "update map" and "print map" From: "Costello, Roger L." <costello@xxxxxxxxx> Date: Thu, 29 Aug 2013 09:16:56 +0000 |
Wow! Thank you Sean, Dimitre, and Wolfgang. You are awesome. Okay, we now have two very fine functions on maps: 1. Update an existing map with another key/value pair 2. Print the contents of a map Below is a complete, working stylesheet which tests the two map functions. /Roger ------------------------------------------------------------ <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:map="http://www.w3.org/2005/xpath-functions/map" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:f="function" version="3.0"> <xsl:template match="/"> <xsl:variable name="m" select="map{'Linda' := 'Rosie'}" /> <xsl:variable name="m1" select="f:add-entry-to-map('Sally', 'Betsy', $m)" /> <xsl:variable name="m2" select="f:add-entry-to-map('Barb', 'Sue', $m1)" /> <xsl:variable name="m3" select="f:add-entry-to-map('Nadia', 'Valerie', $m2)" /> <xsl:variable name="m4" select="f:add-entry-to-map('Faye', 'Carol', $m3)" /> <xsl:sequence select="f:print-map($m4)" /> <!-- The output is: Linda - Rosie Sally - Betsy Barb - Sue Nadia - Valerie Faye - Carol --> </xsl:template> <xsl:function name="f:add-entry-to-map" as="map(xs:anyAtomicType, item()*)"> <xsl:param name="key" as="xs:anyAtomicType" /> <xsl:param name="value" as="item()*" /> <xsl:param name="m" as="map(xs:anyAtomicType, item()*)" /> <xsl:sequence select="map:new(($m, map:entry($key, $value)), map:collation($m) )" /> </xsl:function> <xsl:function name="f:print-map" as="xs:string*"> <xsl:param name="m" as="map(xs:anyAtomicType, item()*)" /> <xsl:sequence select="map:keys($m) !
