Comments are used to provide additional information or draw attention to something in the document. Sometimes, the text being commented is also useful, and you may want to extract it for other purposes. In this article, you will learn how to extract the text between two comment marks in a Word document using Spire.Doc for Java.
Install Spire.Doc for Java
First of all, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Get Text Between Two Comment Marks in Word
To get the text between the start mark (represented by CommentMarkStart class) and the end mark (represented by CommentMarkEnd class), you’ll need to get the indexes of the comment marks. These indexes specify the position of the text being marked in a paragraph. The following are the detailed steps to get text inside two comment marks in a Word document.
- Create a Document object, and load a sample Word document using Document.loadFromFile() method.
- Get the first comment using Document.getComments().get() method.
- Get the start mark and end mark of the comment.
- Get the start mark's index and the end mark's index in the owner paragraph.
- Get the text range between the indexes, and then get the text of the text range using TextRage.getText() method.

import com.spire.doc.Document;
import com.spire.doc.documents.CommentMark;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.Comment;
import com.spire.doc.fields.TextRange;
public class GetTextInsideCommentMarkers {
public static void main(String[] args) {
//Create a Document object
Document doc = new Document();
//Load the sample Word document
doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\Input.docx");
//Get the first comment
Comment comment = doc.getComments().get(0);
//Get the start mark and end mark of the comment
Paragraph para = comment.getOwnerParagraph();
CommentMark start = comment.getCommentMarkStart();
CommentMark end = comment.getCommentMarkEnd();
//Get the start mark’s index and the end mark’s index respectively
int indexOfStart = para.getChildObjects().indexOf(start);
int indexOfEnd = para.getChildObjects().indexOf(end);
//Declare a String variable
String textMarked = "";
//Loop through the numbers between two indexes
for (int i = indexOfStart + 1; i < indexOfEnd; i++) {
if (para.getChildObjects().get(i) instanceof TextRange) {
//Get the text range specified by the index
TextRange range = (TextRange) para.getChildObjects().get(i);
//Get text from the text range
textMarked += range.getText();
}
}
//Print out the text being marked
System.out.println(textMarked);
}
}

This article demonstrates how to extract files from a PDF portfolio in Java using Spire.PDF for Java.
The input PDF:
import com.spire.pdf.PdfDocument;
import com.spire.pdf.attachments.PdfAttachment;
import java.io.*;
public class ReadPortfolio {
public static void main(String []args) throws IOException {
//Create a PdfDocument instance
PdfDocument pdf = new PdfDocument();
//Load the PDF file
pdf.loadFromFile("Portfolio.pdf");
//Loop through the attachments in the file
for(PdfAttachment attachment : (Iterable)pdf.getAttachments()){
//Extract files
String fileName = attachment.getFileName();
OutputStream fos = new FileOutputStream("extract/" + fileName);
fos.write(attachment.getData());
}
pdf.dispose();
}
}
Output:
