I'm looking to build up an open cookbook of XSLT recipes and SVG is a particularly interesting new area. Do you think you have any you could contribute from your current project? This is an open question for anyone on the list. FO is also something that I could use help with. >... > ${$col1} > but xalan doesn't accept these syntaxes !!! > > Do you know how to access to a variable of a variable ? >... I don't think it is possible. There are really very few programming languages where it *is* possible and even in those ones it isn't easy. Variable names are just labels for places that store information. They aren't first-class objects that you should be manipulating in your programs. There must be another way to solve the same problem. If you explain the underlying problem, we might be able to help you find a solution that doesn't involve "meta-variables." For instance here's one idea: <xsl:choose> <xsl:variable name="col-val"> <xsl:when test="$col='HOUR'"/> <xsl:value-of select="$HOUR"/> </xsl:when> <xsl:when test="$col='DAY'"/> <xsl:value-of select="$DAY"/> </xsl:when> </xsl:choose> -- Take a recipe.
