Read Docx in Java

How to read document docx in java??

Berikut source code bagaimanan membaca isi dokumen berekstensi docx pada java. Pada java, untuk membaca file berekstensi docx tidak memerlukan library khusus, teknik pembacaan dokumen docx ini dengan mengekstrak menggunakan zipEntry. Kemudian dari hasil ekstrakan tersebut disimpan pada file xml sebagai penyimpanan temporary, dan terakhir membaca file xml tesebut.

Berikut source code membaca file docx menggunakan java:

import java.io.ByteArrayInputStream;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

public class JavaReadDocx {
    public static void main(String[] args) throws IOException, ParserConfigurationException, SAXException {
        FileInputStream file = new FileInputStream("my.docx");

        ZipInputStream docXFile = new ZipInputStream(file);
        ZipEntry zipEntry;
        OutputStream out;
        String xml = "";
        while ((zipEntry = docXFile.getNextEntry()) != null) {
            if (zipEntry.toString().equals("word/document.xml")) {
                byte[] buffer = new byte[1024 * 4];
                long count = 0;
                int n = 0;
                long size = zipEntry.getSize();
                out = System.out;

                while (-1 != (n = docXFile.read(buffer)) && count < size) {
                    xml += new String(buffer, 0, n);
                    count += n;
                }
            }
        }
        InputStream is = new ByteArrayInputStream(xml.getBytes("UTF-8"));
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder parser = factory.newDocumentBuilder();

        Document document = parser.parse(is);

        NodeList sections = document.getElementsByTagName("w:t");
        String isidocx = "";
        for (int i = 0; i < sections.getLength(); i++) {
            isidocx += sections.item(i).getFirstChild().getNodeValue();
        }
        System.out.println(isidocx);
    }
}
