        BookmarkStart start = para.appendBookmarkStart("bookmark01");
        para.getItems().insert(0,start);
        para.appendBookmarkEnd("bookmark01");

        //Find the specified string
        TextSelection textSelection = doc.findString("It uses symbolic language with deep meaning to reveal the philosophy of life.",false,false);
        TextRange range = textSelection.getAsOneRange();
        Paragraph para = range.getOwnerParagraph();
        int index = para.getChildObjects().indexOf(range);

        //add bookmark
        BookmarkStart start = new BookmarkStart(doc,"Bookmark 1");
        BookmarkEnd end = new BookmarkEnd(doc, "Bookmark 1");
        para.getChildObjects().insert(index, start);
        para.getChildObjects().insert(index + 2, end);

        //Save document
        doc.saveToFile("appendbookmarktocharacter.docx",FileFormat.Docx_2013);
        doc.dispose();

        //Loading documents
        Document doc = new Document();
        doc.loadFromFile("test.docx");

        //Locate specific bookmarks
        BookmarksNavigator bookmarksNavigator = new BookmarksNavigator(doc);
        bookmarksNavigator.moveToBookmark("bookmark1");

        //Delete the content at the bookmark
        bookmarksNavigator.deleteBookmarkContent(true);

        //Delete bookmarks (only delete bookmark labels, the contents of the original signature)
        doc.getBookmarks().remove(doc.getBookmarks().get("bookmark1"));//Delete by book signature
        doc.getBookmarks().removeAt(0);//Delete by index value

        //Save document
        doc.saveToFile("deletebookmark.docx",FileFormat.Docx_2013);
    }
}

[Example 4] Read bookmark text

import com.spire.doc.*;
import com.spire.doc.documents.BookmarksNavigator;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.TextBodyPart;
import com.spire.doc.fields.TextRange;

import java.io.IOException;
import java.io.PrintWriter;

public class GetBookmarkText {
    public static void main(String[]args) throws IOException {
        //Loading bookmarks Word File
        Document doc = new Document();
        doc.loadFromFile("test.docx");

        //Get bookmarks
        BookmarksNavigator bookmarksNavigator = new BookmarksNavigator(doc);
        bookmarksNavigator.moveToBookmark("bookmark1");

        //Getting Bookmark Text
        TextBodyPart textBodyPart = bookmarksNavigator.getBookmarkContent();

        //Establish String variable
        String text = "";

        //Items that traverse bookmark content
        for (Object item : textBodyPart.getBodyItems()) {

            //Determine whether the item is a paragraph
            if (item instanceof Paragraph) {
                Paragraph paragraph = (Paragraph) item;

                //Traversing subobjects in paragraphs
                for (Object childObj : paragraph.getChildObjects()) {

                    //Judging whether a child object is TextRange
                    if (childObj instanceof TextRange) {

                        //Obtain TextRange Text in
                        TextRange textRange = (TextRange) childObj;
                        text = text + textRange.getText();
                    }
                }
            }
        }

        //Write the retrieved text Txt file
        PrintWriter printWriter = new PrintWriter("BookmarkText.txt");
        printWriter.println(text);
        printWriter.close();
    }
}
