Java extracts text content of SmartArt shapes in PowerPoint

In the previous article, I introduced How to add SmartArt shapes to PowerPoint, but today I will extract the text content of SmartArt shapes with a Java program. I will show you how. (Library: Free Spire.Presentation for Java)

** Import JAR package ** ** Method 1: ** After downloading and unzipping Free Spire.Presentation for Java, in the lib folder Import the Spire.Presentation.jar package into your Java application as a dependency.

** Method 2: ** After installing the JAR package directly from the Maven repository, configure the pom.xml file as follows:

<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <name>e-iceblue</name>
            <url>http://repo.e-iceblue.com/nexus/content/groups/public/</url>
        </repository>
</repositories>
<dependencies>
    <dependency>
        <groupId>e-iceblue</groupId>
        <artifactId>spire.presentation.free</artifactId>
        <version>3.9.0</version>
    </dependency>
</dependencies>

** Java sample code **

import com.spire.presentation.Presentation;
import com.spire.presentation.diagrams.ISmartArt;
import java.io.*;

public class extractTextFromSmartArt {
    public static void main(String[] args) throws Exception {
        Presentation presentation = new Presentation();
        presentation.loadFromFile("SmartArt.pptx");

        //Create a new txt document
        String result = "extractTextFromSmartArt.txt";
        File file=new File(result);
        if(file.exists()){
            file.delete();
        }
        file.createNewFile();
        FileWriter fw =new FileWriter(file,true);
        BufferedWriter bw =new BufferedWriter(fw);

        bw.write("Below is the text extracted from SmartArt." + "\r\n");

        //Loop through all the slides and get the SmartArt shape
        for (int i = 0; i < presentation.getSlides().getCount(); i++)
        {
            for (int j = 0; j < presentation.getSlides().get(i).getShapes().getCount(); j++)
            {
                if (presentation.getSlides().get(i).getShapes().get(j) instanceof ISmartArt)
                {
                    ISmartArt smartArt = (ISmartArt)presentation.getSlides().get(i).getShapes().get(j);

                    //Extract the text that was in SmartArt
                    for (int k = 0; k < smartArt.getNodes().getCount(); k++)
                    {
                        bw.write(smartArt.getNodes().get(k).getTextFrame().getText() + "\r\n");
                    }
                }
            }
        }
        bw.flush();
        bw.close();
        fw.close();

    }
}
