Subject: Re: [xsl] concat with unspecific length From: Wolfgang Laun <wolfgang.laun@xxxxxxxxx> Date: Mon, 18 Jun 2012 16:03:13 +0200 |
You might consider a function pad: <xsl:function name="x:pad" as="xsd:string"> <xsl:param name="s" as="xsd:string"/> <xsl:param name="l" as="xsd:integer"/> <xsl:choose> <xsl:when test="string-length($s) >= $l"> <xsl:sequence select="$s"/> </xsl:when> <xsl:otherwise> <xsl:sequence select="concat(x:pad($s, $l - 1),' ')"/> </xsl:otherwise> </xsl:choose> </xsl:function> which you can call like this x:pad( $Field1, 11 ) You might want to truncate when the string length exceeds the 2nd operand. -W On 18/06/2012, Syd Bauman <Syd_Bauman@xxxxxxxxx> wrote: > Length various based on what?
