appending data to an XML file

Hi can someone help me with appending data to an XML file.

I want to save some data to a XML file which is done by the following code.

VB Code:

Private Sub Command47_Click()
CommonDialog1.ShowSave
NewFileSave = CommonDialog1.FileName
MsgBox NewFileSave
xml.SaveXml NewFileSave
MsgBox "Saved"
CancelButton:
Exit Sub
End Sub

Now if i open an existing file and save my data in that file the original data is lost.

How to append the data to the existing XML file ???

Amit

Urgent help required as i am stuck with this problem.

I am storing some data in the buffer through input from a GUI and am saving the data using the code mentioned in the 1st post to a new XML file but i am not able to append the same data stored in the buffer to an existing XML file.

Can anyone help me out ??????

Thanks,
Amit

Here is the code to append xml:

VB Code:

Sub Append_XML_Element(oXMLfile As String)
' Requires msxml.dll (Go to Project --> References and and choose Microsoft XML version 2.0, or whatever the
' current version you have installed)
    Dim objDom As New MSXML2.DOMDocument26
    Dim objRootElem As IXMLDOMElement
    Dim objSubRootElem As IXMLDOMElement
    Dim objMemberElem As IXMLDOMElement
 
    'Load xml files
    objDom.async = False
    objDom.Load oXMLfile
 
    ' Loads root element
    Set objRootElem = objDom.documentElement
 
    ' Creates sub root element
    Set objSubRootElem = objDom.createElement("MySubRootElement")
    objRootElem.appendChild objSubRootElem
 
    ' Creates Error Date & Time element
    Set objMemberElem = objDom.createElement("DateTime")
    objSubRootElem.appendChild objMemberElem
    objMemberElem.Text = Format(Now, "DD-MMM-YYYY hh:mm:ss")
 
    ' Saves XML data to disk.
    objDom.save oXMLfile
 
ExitHere:
    Err.Clear
    Set objDom = Nothing
End Sub

Please modify as per your need.

Thanks for the hep but what i am going to append is not predefined and is only entered by the user using a gui and i need to save the enteries made by the user to the exisiting XML file

No probs! Change the field name and its value in the above code as per your requirement.

Are you appending the data or going to edit existing data?

For any data there will be a constant field name and in run time the user will enter the value for that field right. So, if you have filed "Student Name" and in run time the user is entering the name of the student "Amit" in a text box (Let's say name of the text box txtStudent) then in above code you need to change as:

VB Code:

' Creates Student Name element
    Set objMemberElem = objDom.createElement("StudentName")
    objSubRootElem.appendChild objMemberElem
    objMemberElem.Text = txtStudent.Text

Everytime you need to use this code to append a new node on xml.
