Subject: [xsl] Concat function returning nodeset when param is part of arguments From: Alex Muir <alex.g.muir@xxxxxxxxx> Date: Fri, 16 Oct 2009 13:28:20 +0000 |
Hi, Running my code in version 11 of oxygen I'm getting the following error on the matches function in the when test in the code below Severity: error Description: Attempting to access a sequence as a singleton item <?xml version="1.0"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0"> ... <xsl:param name="regex_string_tags" as="xs:string" select="'\[\[B\]\]'"/> ... <xsl:variable name="matchingString" as="xs:string" select="concat('^',$regex_string_tags,'(##[^#]+?##|\s)*?\[\[FONT')"/> ... <xsl:when test="matches(.,$matchingString,$regex_flags)"> In the debugger it is stating that the variable matchingString is a nodeset(5) rather than the string I would have expected. I noticed that if I remove the parameter from the concat statement and replace it with 'some string' it then returns a string as I expect also if I change the param into a variable it returns a string. <xsl:variable name="matchingString" as="xs:string" select="concat('^','some string','(##[^#]+?##|\s)*?\[\[FONT')"/> So why is the parameter having this effect? I suppose I could have made a change I didn't notice however this was working in version 10.3 of oxygen. Thanks -- Alex https://sites.google.com/a/utg.edu.gm/alex
