Set merge fields

The example shows you how to retrieve all merge fields from a document and set their values. See pictures below how document looks like before and after update.

import java.util.List;

import com.independentsoft.office.IContentElement;
import com.independentsoft.office.word.Run;
import com.independentsoft.office.word.WordDocument;
import com.independentsoft.office.word.fields.MergeField;
import com.independentsoft.office.word.fields.SimpleField;

public class Example {

    public static void main(String[] args)
    {
        try
        {
            String customerID = "12345";
            String customerName = "John Smith";
            String customerAddress = "123 Way, New York, NY 10019";

            WordDocument doc = new WordDocument("c:\\test\\input.docx");

            List<IContentElement> docElements = doc.getContentElements();

            for(IContentElement docElement : docElements)
            {
                if (docElement instanceof SimpleField)
                {
                    SimpleField simpleField = (SimpleField)docElement;

                    if (simpleField.getField() instanceof MergeField)
                    {
                        MergeField mergeField = (MergeField)simpleField.getField();

                        if (mergeField.getName().equals("CustomerID"))
                        {
                            Run run = new Run(customerID);

                            simpleField.getContent().clear();
                            simpleField.add(run);
                        }
                        else if (mergeField.getName().equals("CustomerName"))
                        {
                            Run run = new Run(customerName);

                            simpleField.getContent().clear();
                            simpleField.add(run);
                        }
                        else if (mergeField.getName().equals("CustomerAddress"))
                        {
                            Run run = new Run(customerAddress);

                            simpleField.getContent().clear();
                            simpleField.add(run);
                        }
                    }
                }
            }
            doc.save("c:\\test\\output.docx", true);
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
            e.printStackTrace();
        }
    }
}
