Its more a question of how you intend to invoke the XSLT processor, and where you want logic to occur. Consider the following snippet, amended from your original xslt; <td><a href="dosomemoreprocessing.asp?person-name={person-name}"><xsl:value-of select="person-name"/></a></td> Note I have used curly brackets {} which is shorthand (avt) for placing the value of the element person-name element. Using HTTP GET ( that is passing var within the url ), you pass the variable person-name to another asp that performs another transform, that performs the query and applies some xslt processing the the resultant xml. You may find that its easier to have a generic ASP xslt processing page, then just leave it to xslt to 'do the thinking'. This will undoubtably be something you have done previously.... Additionally, by using xsl:param you can instruct the XSLT processor to pass a parameter to your XSLT from the ASP page. That way you can let ASP page be your 'controller', as set within a Model View Controller, and let you XSLT provide the 'View', as well as updating the 'Model'. It struck me that this sample chapter might assist; http://www.perfectxml.com/wp/readchap.asp?CurBook=3 > would i do that . Do i have to call etxernal objects > from XSL to call the the search . When u say 'external objects', I understand it as 'do I have to call another ASP page for initiating some other XSLT process'...which the answer to is yes. XSLT main purpose in life is to transform xml into another form of xml; or in a larger sense transforming data into another form of data....many people view it as a programming language perhaps because a lot of what programming languages do is marshal data from one form to another. In general, be careful where you place your application logic, in the ASP or the XSLT....( though I don't work with ASP ), in general place logic in XSLT if its more generally applicable, as you may find yourself using the XSLT in another programming context; embed application specific logic within the ASP. This is a rule of thumb that has served me well over the years. > Any thoughts appreciated .NET, whilst not incompatible with xslt per say, comes along with a particular framework and approach here are a few sites which may assist you; http://www.dpawson.co.uk http://www.topxml.com/ another good site which describes the MSXML approach ( microsoft's XSLT processor which is used in .NET ) go here http://www.perfectxml.com/msxmlxslt.asp.
