Re: Release Date vs. Highlight Until Date
john, xslt version 1 does not support type checking, everything is more or less just text. so doing date parsing is kind of tedious, still possible (depending on how complex the check is). you probably could pass the current date as a parameter to the xsltransformer and let the stylesheet do the checking using regular expression and alike. or, if the date is stored in the xs:datetime format, an alphabetic sort will do, then you will need to select only the first 5 elements. (if it4s based on novelty) maybe you will think about letting .net decide weather a xml file qualifies for the main page or not and pass the result (the n selected filenames) as a parameter to the xslt file, which then just 'dumbly' transforms. another possibility is to use a xslt 2.0 transformer (saxon) but the .net implementation is still very at its beginning and IMHO the .net transformer is currently more user friendly and stable. just my 55 -- jan On Mon, 20 Sep 2004 19:15:18 -0400, xsl-list <xsl-list@xxxxxxxx> wrote: > Hi, > > I am new to the list and XSL in general, so I apologize if this is the wrong > forum for this question.
