chemical formular with subscipted numbers

[Heinz4711]

Hello,

using Spire.doc, how can I replace an exiting text in a DOCX document with chemical formular with subscipted numbers ?

So for example I have a „MatchText“ in DOCX and need this match text to be replaced with „result text“ in my DOCX

Something like this:

Replace_chemical_formular (doc,“O2“);

            document.LoadFromFile("test.docx");

            Document newDocument = new Document();
            Paragraph chemical = newDocument.AddSection().AddParagraph();
            TextRange subscript = new TextRange(newDocument);


            subscript.Text = "2";
            subscript.CharacterFormat.SubSuperScript = SubSuperScript.SubScript;
            chemical.AppendText("O");
            chemical.ChildObjects.Add(subscript.Clone());
            TextSelection textSelections1 = newDocument.FindString(chemical.Text, true, true);
            document.Replace(chemical.Text, textSelections1,true,true);
            chemical = newDocument.AddSection().AddParagraph();

            subscript.Text = "2";
            subscript.CharacterFormat.SubSuperScript = SubSuperScript.SubScript;
            chemical.AppendText("N");
            chemical.ChildObjects.Add(subscript.Clone());
            textSelections1 = newDocument.FindString(chemical.Text, true, true);
            document.Replace(chemical.Text, textSelections1, true, true);
            chemical.ChildObjects.Clear();

            subscript.Text = "2";
            subscript.CharacterFormat.SubSuperScript = SubSuperScript.SubScript;
            chemical.AppendText("H");
            chemical.ChildObjects.Add(subscript.Clone());
            chemical.AppendText("O");
            textSelections1 = newDocument.FindString(chemical.Text, true, true);
            document.Replace(chemical.Text, textSelections1, true, true);
            chemical.ChildObjects.Clear();

            subscript.Text = "4";
            subscript.CharacterFormat.SubSuperScript = SubSuperScript.SubScript;
            chemical.AppendText("CH");
            chemical.ChildObjects.Add(subscript);
            textSelections1 = newDocument.FindString(chemical.Text, true, true);
            document.Replace(chemical.Text, textSelections1, true, true);

            subscript.Text = "4";
            chemical.ChildObjects.Add(subscript.Clone());
            chemical.AppendText("C");
            textSelections1 = newDocument.FindString(chemical.Text, true, true);
