copied!<p>In you xsl create a <code>xsl:parameter</code> at the top before all your templates.</p> <pre><code><xsl:parameter name="showdate"/> </code></pre> <p>You can now treat this like you would a variable:-</p> <pre><code><xsl:when test="@date = $showdate"> </code></pre> <p>In order to pass a parameter in you need to use an XSL processor object which allows you to add the parameter before processing. In turn you get a processor from an instance of an XSL Template object. In turn you need a FreeThreadedDOMDocument to assign to the templates stylesheet parameter. Hence the code is more complex:-</p> <pre><code> Dim xsl : Set xsl = CreateObject("MSXML2.FreeThreadedDOMDocument.3.0") xsl.async = false xsl.load xslFile Dim xml : Set xml = CreateObject("MSXML2.DOMDocument.3.0") xml.async = false xml.load sourceFile Dim xslTemplate : Set xslTemplate = CreateObject("MSXML2.XSLTemplate.3.0") xslTemplate.stylesheet = xsl; Dim processor : Set processor = xslTemplate.createProcessor() processor.addParameter "showDate", "20091203" processor.input = source processor.transform() Response.Write processor.output </code></pre> <p>Its tempting to assign the Response object to the processor's output parameter which works quite well and is more efficient. However recent Service packs of MSXML have made such a technique incompatible with ASP's implementation of IStream in the Response object.</p> <p>So thats how you do it officially, how I do it normally is to inject some arbitary attribute on to the source XML's root node then use a variable:-</p> <pre><code>xml.documentElement.setAttribute("_showDate", "20091203") </code></pre> <p>Now you can use a variable instead of a parameter inside your main template:-</p> <pre><code><xsl:template match="rota"> <xsl:variable name="showdate" select="@_showDate" /> <html> ... <xsl:when test="@date = $showdate"> </code></pre> <p>In this approach you can use the transform code you are already using which is much simpler.</p>
