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.

Answer 1

If the text you are looking for is placed between brackets and Word Splits your text in multiple runs...;

Search the text (ienumerable(of text))

for (int i = 0; i <= SearchIn.Count - 1; i++) {

    if (!(i + 2 > SearchIn.Count - 1)) {
        Text TXT = SearchIn(i);
        Text TXT1 = SearchIn(i + 1);
        Text TXT2 = SearchIn(i + 2);

        if (Strings.Trim(TXT.Text) == "[" & Strings.Trim(TXT2.Text) == "]") {
            TXT1.Text = TXT.Text + TXT1.Text + TXT2.Text;

            TXT.Text = "";
            TXT2.Text = "";
        }
    }
}
