This is great. Thanks man.
I'd Just need one more help. I want it to copy the nodes without any private.* as well.

So far I have got.

var rangefrom = Convert.ToInt32(startingRangetextbox.Text);
var rangeto = Convert.ToInt32(RangeTotxtbx.Text);
XDocument xdoc = XDocument.Load(FilePathtxtbx.Text);

var dir = Path.GetDirectoryName(FilePathtxtbx.Text);
var file = Path.GetFileName(FilePathtxtbx.Text);

for (var i = rangefrom; i <= rangeto; i++)
{
    //define search criteria
    string searchterm = "private";
    StringComparison comparison = StringComparison.InvariantCulture;

    //create instance of XDocument

    //define parent node  for ObjectType nodes
    var otsparent = xdoc.Descendants("Types").SingleOrDefault();
    var eosparent = xdoc.Descendants("ExportedObjects").SingleOrDefault();

    //find ObjectType nodes Name starts with "private"
    var ots2copy = xdoc.Descendants("ObjectType")
        .Where(x => x.Attribute("Name").Value.StartsWith(searchterm, comparison))
        .ToList();
    var eos2copy = xdoc.Descendants("OI")
        .Where(x => x.Attribute("TYPE").Value.StartsWith(searchterm, comparison))
        .ToList();
    var eos = xdoc.Descendants("OI");

    //loop through the list of nodes which meet criteria
    //int i = 1;
    foreach (XElement original in ots2copy)
    {
        //create deep copy of original node
        XElement copy = new XElement(original);
        //change Name attribute
        copy.Attribute("Name").Value += i.ToString();
        //add a copy to parent node
        otsparent.Add(copy);
        //i++;
    }
    //int j = 1;
    foreach (XElement original in eos2copy)
    {
        //create deep copy of original node
        XElement copy = new XElement(original);
        //change Name attribute
        //if (copy.Attribute("TYPE").Value.StartsWith(searchterm, comparison))
        //{
       
        //    copy.Attribute("TYPE").Value += i.ToString(); //GETTING OUT OF MEMORY EXCEPTION HERE WITH VALUE private.*1111111111111111111111111111111111...........
        //    //add a copy to parent node
        //    eosparent.Add(copy);
        //}
        //j++;

        copy.Attribute("TYPE").Value += i.ToString();
        //add a copy to parent node
        eosparent.Add(copy);
        //j++;
    }
}

I do not have control over the source of the file. I made the sample file for the question. usually, type node will have 100's of ObjectType Node and same goes for OI node in ExportedObjects.

I wanna be able to duplicate all the child nodes of type node and append it within that node and append Name attribute with 1,2,3 etc IF it startswith "private.*". Same with ExportedObjects, but here attribute TYPE contains the private.* value which will be appended with 1,2,3 depending on the on the number of copy (value of i).

I hope I am explaining it right.

The one I am working with atm is about an MB

Hope it makes sense now.

Clearly I need to improve that skill

Thanks man. I have updated the question

no, I am reading XML as a string and then replacing it using string.replace

multiline is the type of Textbox I am using

I don't know how many strings user wants to be replaced.

Sorry, I am not very good at explaining. I hope the question makes sense now. Thanks

List of line123 is in findtxtbx and the list of replaceline123 is in replacewithtxtbx
