Updating the XML file using ASP or any other method.

[paragguptaiiita]

I have a XML file and for that XML file i have created a XSL file in which i am showing the data of XML file in text area so that when we view the XML file,we can also edit that XML file. now can anyone tell me that how can we update the XML file.
The code present on web is for small XML File
Just like this
Just Check it

but how can we edit large XML file in which a node contains 3-4 attributes and 3-4 child also and each child contains the 3-4 attributes.

It's fairly simple.

In this case, I would return all the parent level tags, and while looping through them, I would manipulate their child nodes.

Example:

Set oXML = Server.CreateObject("msxml2.DOMDocument") 
oXML.async=true 
oXML.Load(Server.MapPath("/Path/To/Your/Document.xml)) 
Set oRoot = oXML.DocumentElement
Set oParent = oRoot.GetElementsByTagName("YourElement")
For i = 0 To (oParent.Length - 1)
  'You can set the text of a node like this...
  oParent.Item(i).text
  'You can set the attribute of a node like this...
  oParent.Item(i).SetAttribute("AttributeName") = "whatever"
  'You can GET the attribute of a node like this..
  oParent.Item(i).GetAttribute("AttributeName")
  'You can append a new node like this..
  Set oNewNode = oXML.CreateElement("whatever")
  oXML.AppendChild oNewNode
  Set oNewNode = Nothing
  'Loop through your child nodes.
  For h = 0 to oParent.ChildNodes.Length - 1
    'set text..
    'oParent.ChildNodes.Item(h).text = "whatever"
    'set attribute
    oParent.ChildNodes.Item(h).SetAttribute = "whatever"
    'get attribute
    oParent.ChildNodes.Item(h).GetAttribute
    'Append a new node
    Set oNewNode = oXML.CreateElement("whatever")
    oParent.Item(i).AppendChild oNewNode
    Set oNewNode = Nothing
  Next
Next
oXML.Save(server.Mappath("/Path/To/Your/Document.xml"))
Set oXML = Nothing
 

Play around with it. Hope it helps.

Sincerely,
Mark
