Subject: [xsl] Using @validation and @type? From: "David Birnbaum djbpitt@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Tue, 26 Nov 2019 01:38:37 -0000 |
Dear XSL-list, I'm beginning to explore schema-aware processing, and for a real project I need to create some temporary elements with attributes that I would like to treat as integers. In the non-schema-aware version I explicitly pass the attributes through the number() function when I need integer behavior, and that does what I want, but I thought that if I typed the values as xs:integer when creating them they would be recognized as instances of that type when used, and would have integer behavior, so that I could avoid using the number() function explicitly. I created a small test sample below that replicates the problem I see in my real code, and I would be grateful if someone could please advise about what I've misunderstood. What I think I'm doing is creating a a variable that contains <cell> elements with @row attributes that are typed as xs:integer, and that therefore should behave as integers when I use them. But when I test in the <xsl:for-each> at the end whether they are instances of integers, the system reports that they are not. I'm running the tests at the command line with Saxon EE and the -sa and -it switches. Thank you for any guidance you might be able to provide. Best, David __ <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" exclude-result-prefixes="xs" version="3.0"> <xsl:output method="xml" indent="yes"/> <xsl:template name="xsl:initial-template"> <xsl:variable name="test" as="element(test)"> <test xsl:validation="preserve"> <xsl:for-each select="1 to 5"> <cell> <xsl:attribute name="row" type="xs:integer" select="."/> <xsl:text>Hi!</xsl:text> </cell> </xsl:for-each> </test> </xsl:variable> <xsl:for-each select="$test//cell"> <xsl:message select="@row, @row instance of xs:integer"/> </xsl:for-each> <root> <xsl:sequence select="$test"/> </root> </xsl:template> </xsl:stylesheet>
