Hi I am feeling a bit lost and confused with XML. I am trying to build a very simple web app that will get its data from an XML file which has been created from a SQL server. The application allows the user to hold a contact details on there laptops in a disconnected environment. They only need to be able to read the data and no editing or inputting is required. So I build an XML file using ado.net, I would like the user to be able to query the xml file via a textbox. So if the user types in 'Sam' it will go away and pull out all Contacts with the first name Sam and fill a datagrid with teh results. However I am a bit confused on how I query a XML file also do I have to put it in a dataset before I can fill a datagrid? I briefly heard that I should be using XPath, XQuery or something like XSL. I have never really used XML, all I want to do is pass it one parameter. My code looks like teh below: Dim dsWards As New DataSet() dsWards.ReadXml(Server.MapPath("Contacts.xml")) DataGrid1.DataSource = dsWards DataGrid1.DataBind() I would be grateful for some simle examples that I could have a look at in VB.Net. Also I am using Visual Studio .Net 2003, does this come with any tools that will help me query an XML file? I just feel a bit lost and cant find any good examples PS All the users will have IIS running on their machines
