How can i read it?Kindly Guide me please Thanks, Deepak kr_deepak123@hotmail.com kr_deepak123@yahoo.co.in > Hi All, > [quoted text clipped - 23 lines] > kr_deepak123@hotmail.com > kr_deepak123@yahoo.co.in With a small document like this you can use XmlDocument from Sytem.Xml. Load the XML: doc.LoadXml(myTextbox.text) Read the EarlyStart data: XmlNode start = doc.SelectSingleNode("/*/EarlyStart") Convert to a DateTime: DateTime dt = XmlConvert.ToDateTime(start.InnerText, XmlDateTimeSerializationMode.Utc) (May want to change the serialization mode enum depending on what you do with the info.)

Hi Joe, the question is that how to get this xml as there is no textbox in real production environment and this xml message will come through internet via http protocol. tHIS PAGE dont play any role in actual production environment and this is just asumption that we r goign to process the message of production (present in this text box) through this page but in actual the same xmlmessage willcome through http protocol... then how to get the xml message through request object like request.form.getvalues(...).....Kinldy tell me i would be highly helped by this? > Hi Joe, > [quoted text clipped - 41 lines] > > (May want to change the serialization mode enum depending on what you do > > with the info.) > Actually this asp.net page(having text box) is just a demo within us but in > production environment with customers, they will send this xml message > through http protocol then how we shoudl read this...kindly tell me i would > be greatful to u... Assuming you have an ASP.NET page and that receives a HTTP POST request with the XML in the request body then you can read in the XML as follows Dim doc As New XmlDocument() Try doc.Load(Request.InputStream) ' now use doc here e.g. Dim earlyStart As XmlNode = doc.SelectSingleNode("SXPTaskUpdateOrAdd/Task/EarlyStart") Catch e As XmlException ' handle exception here End Try SignatureMartin Honnen --- MVP XML http://JavaScript.FAQTs.com/ Hi Martin, Hope u r fine. I tried your code i.e. Request.InputStream but its giving me 'nothing' in quick watch of Visual Studio IDE then i tried Request.Form.Item("SXP").GetValue(0) ,its also giving me nothing(and hence error object refrce not set to instance of object) but if i try to add any attachment file (say hi.txt) through 2nd texbox present in the asp.net page(as i tokd u before ther are 2 textboxex available on that asp.net page 1. for sending sxptaskuodate or add message 2. for adding any attachment with sxptaskupdateoradd mesage after browsing the file say hi.txt. so if i try to add any attachment and then lick on submit while sending the sxptaskupdateoradd message , i gets that entire sxp message in Request.Form.Item("SXP").GetValue(0) as string i.e. "<SXPTaskUpdateORAdd...." why it is so means the question is that if i add any attachment then i can read this sxptaskupdateorAdd in Request.Form.Item("SXP").GetValue(0) but if i dont add any attachment file i.e. that texbox having path of file is empty then i dont get anything in Request.Form.Item("SXP").GetValue(0) and gets "object refercene not set to instance...." error .My aim is to read that sxptaskupdateoradd message even if there is no attachment file with this message.Your way Request.InputStream is giving me null value. In actual producion environment this SXPTaskUpdateorAdd will come via http protocol throgh internet and this asp.net demo page will not be there.This page is with us just to do testing on our side as a demo assmuing that this message is comign from customer side. Kindly give some more efforts,it would be great help for me and my project really. - Deepak kr_deepak123@hotmail.com kr_deepak123@yahoo.co.in > > Actually this asp.net page(having text box) is just a demo within us but in > > production environment with customers, they will send this xml message [quoted text clipped - 13 lines] > ' handle exception here > End Try > In actual producion environment this SXPTaskUpdateorAdd will come via http > protocol throgh internet and this asp.net demo page will not be there.This > page is with us just to do testing on our side as a demo assmuing that this > message is comign from customer side. Well my suggestion to use Request.InputStream is meant to be used when you have an ASP.NET page to which someone makes a HTTP POST request with the XML sent in the request body. So assuming you have http://example.com/receive.aspx and someone makes a HTTP POST request to that URL then you can use Request.InputStream and read out the posted XML.

Hi Martin, your method of using Request.InputStream is working fine.i juct debugged and checked and its showing values in quick watch...thanks a lot again....really..
