Replace Text in Word document using Open Xml

Question

I have created a docx file from a word template, now I am accessing the copied docx file and want to replace certain text with some other data.

I am unable to get the hint as to how to access the text from the doument main part?

Any help would be appreciable.

Below is my code till now.

private void CreateSampleWordDocument()
    {
        //string sourceFile = Path.Combine("D:\\GeneralLetter.dot");
        //string destinationFile = Path.Combine("D:\\New.doc");
        string sourceFile = Path.Combine("D:\\GeneralWelcomeLetter.docx");
        string destinationFile = Path.Combine("D:\\New.docx");
        try
        {
            // Create a copy of the template file and open the copy
            File.Copy(sourceFile, destinationFile, true);
            using (WordprocessingDocument document = WordprocessingDocument.Open(destinationFile, true))
            {
                // Change the document type to Document
                document.ChangeDocumentType(DocumentFormat.OpenXml.WordprocessingDocumentType.Document);
                //Get the Main Part of the document
                MainDocumentPart mainPart = document.MainDocumentPart;
                mainPart.Document.Save();
            }
        }
        catch
        {
        }
    }

Now how to find certain text and replace the same? I am unable to get via Link, so some code hint would be appreciable.

Just to give you the idea of how to do it, please try:

  using ( WordprocessingDocument doc =
                    WordprocessingDocument.Open(@"yourpath\testdocument.docx", true))
            {
                var body = doc.MainDocumentPart.Document.Body;
                var paras = body.Elements<Paragraph>();

                foreach (var para in paras)
                {
                    foreach (var run in para.Elements<Run>())
                    {
                        foreach (var text in run.Elements<Text>())
                        {
                            if (text.Text.Contains("text-to-replace"))
                            {
                                text.Text = text.Text.Replace("text-to-replace", "replaced-text");
                            }
                        }
                    }
                }
            }
        }

Please note the text is case sensitive. The text formatting won't be changed after the replace. Hope this helps you.
