Subject: [xsl] Re: Using XSL parameters to construct variables to construct expressions From: "Dimitre Novatchev" <dnovatchev@xxxxxxxxx> Date: Fri, 21 Mar 2003 06:53:22 +0100 |

And in this case dynamic evaluation is not necessary -- use: <xsl:apply-templates select="process[starts-with(number, $processArea)]"/> ===== Cheers, Dimitre Novatchev. http://fxsl.sourceforge.net/ -- the home of FXSL XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
