For instance if $lcpath contains /images/dir.path/file.png how do I set $ext to be "png"? Below is the best I have been able to come up with - suggestions greatly appreciated. <xsl:variable name="lcpath" select="/images/dir.path/file.png" /> <xsl:variable name="pos"> <xsl:choose> <xsl:when test="substring( $lcpath, string-length( $lcpath ) - 5, 1 ) = '.'">4</xsl:when> <xsl:when test="substring( $lcpath, string-length( $lcpath ) - 4, 1 ) = '.'">3</xsl:when> <xsl:when test="substring( $lcpath, string-length( $lcpath ) - 3, 1 ) = '.'">2</xsl:when> <xsl:when test="substring( $lcpath, string-length( $lcpath ) - 2, 1 ) = '.'">1</xsl:when> <xsl:otherwise>0</xsl:otherwise> </xsl:choose> </xsl:variable> <xsl:variable name="ext" select="substring( $lcpath, string-length( $lcpath ) - $pos )" /> Current Thread Determine file extension of path stored in variable John - 27 Dec 2004 16:23:55 -0000 <= Mukul Gandhi - 27 Dec 2004 17:53:43 -0000 John - 28 Dec 2004 17:15:48 -0000 Mukul Gandhi - 29 Dec 2004 12:48:47 -0000 <- Previous Index Next -> RE: XSL Transformation!!, cknell Thread Re: Determine file extension , Mukul Gandhi Re: Transformations between d, Garfield Date Re: Radio Button Values, Thorr Giddings Month
