All filtering to be client-side processing. Yes, you can do this, as long as you don't expect $parameterString to be an XPath expression itself. For example, you can declare the parameter: <xsl:param name="parameterString" select="'groupA'" /> and then do something like: <xsl:if test="contains($parameterString, 'groupA')"> ... process groupA elements ... </xsl:if> Passing in parameters to stylesheets involves scripting the transformation on the client, and using the MSXML3 or MSXML4 methods to do so, via XSLTemplate and XSLProcessor objects. The MSXML documentation contains examples -- look up the addParameter() method for an example. > Any other alternatives for client-side filtering of xml data where > multiple selections can be made (i.e., I want groupA, groupB and > groupD data displayed, but not groupC) or - I just want groupB data > - could be any combination of groupA thru groupX. You could consider doing this through client-side scripting of the display of the groups through their CSS style rather than through XSLT. For example, define a function in the HTML that you generate that toggles between showing or hiding the passed element: function toggle(element) { if (element.style.display = 'block') { element.style.display = 'none'; } else { element.style.display = 'block'; } } and then have buttons that you click to show or hide the element: <a onclick="toggle(groupA)">Show/Hide</a> <div id="groupA"> ... </div> Doing it like this is likely to be less effort for the browser, I think, and it makes the transformation a lot easier :) Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
