Re: [xsl] boolean values
Subject: Re: [xsl] boolean values From: David Carlisle <davidc@xxxxxxxxx> Date: Thu, 28 Aug 2003 12:07:06 +0100 |
<xsl:variable name="hasContracts" select=" count(/Output[$branding = 'ABC']/Contracts/Contract[substring(ContractId, 1,1)='Q']) > 0 or boolean(/Output[$branding != 'ABC']/Contracts/Contract) "/> although since a test of count() > 0 is just testing if the node set is non empty, and boolean() does the same, and substring 1,1 is the start of the string, this can be simplified to <xsl:variable name="hasContracts" select=" /Output[$branding = 'ABC']/Contracts/Contract[starts-with(ContractId,'Q')] or /Output[$branding != 'ABC']/Contracts/Contract "/> which makes it clearer that it can be further simplified to <xsl:variable name="hasContracts" select=" boolean(/Output/Contracts/Contract[($branding = 'ABC' and starts-with(ContractId,'Q')) or not($branding = 'ABC')]) "/> which is probably closer to the original description of the problem.
