Subject: Re: [xsl] Passing xs:string containing zero characters From: David Carlisle <davidc@xxxxxxxxx> Date: Wed, 19 May 2010 09:22:19 +0100 |
Hi!
I'm new to XSLT 2.0 and using it with Saxon 9.1 in DITA-Open Toolkit. I wrote following variable and pass it as a parameter as $prmLang to the template.
<xsl:variable name="lang" as="xs:string" select="string(@xml:lang)"/>
<xsl:apply-templates select="child::*[contains(@class, ' topic/related-links ')]"> <xsl:with-param name="prmLang" as ="xs:string" select="$lang"/> </xsl:aplly-templates>
<xsl:template match="*[contains(@class, ' topic/related-links ')]"> <xsl:param name="prmLang" as="xs:string" required="yes"/> ... </xsl:template>
Then the following error is occured when $lang is empty string.
"[xslt] D:\DITA-OT1.5-FB\demo\xxx\xsl\xxx_dita2fo_relatedlinks.xsl:34: Fatal Error! No value supplied for required parameter"
Is it a right behavior? I thought that xs:string can contain any sequence of zero or more characters.
(If I rewrite the template code required="yes" to select="''", then it works fine.)
