.docxファイルループ内のすべての段落をコピーできますdoc.getParagraphs()
ただしTable、段落でTableはないため、コピーされません。
をコピーTableするには、取得IBodyElementしてループする必要がありますdoc.getBodyElements()。
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.xmlbeans.XmlException;
public class WordFinal {
public static void main(String[] args) throws IOException, XmlException {
XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx"));
XWPFDocument destDoc = new XWPFDocument();
OutputStream out = new FileOutputStream("Destination.docx");
// ** This code will copy just one paragraph. **
XWPFParagraph pr = doc.getParagraphs().get(0);
destDoc.createParagraph();
int pos = destDoc.getParagraphs().size() - 1;
destDoc.setParagraph(pr, pos);
destDoc.write(out);
}
}
したがって、すべての段落と表をコピーするコードは次のようになります。
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import org.apache.poi.xwpf.usermodel.BodyElementType;
import org.apache.poi.xwpf.usermodel.IBodyElement;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.xmlbeans.XmlException;
public class WordFinal {
public static void main(String[] args) throws IOException, XmlException {
XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx"));
XWPFDocument destDoc = new XWPFDocument();
OutputStream out = new FileOutputStream("Destination.docx");
for (IBodyElement bodyElement : doc.getBodyElements()) {
BodyElementType elementType = bodyElement.getElementType();
if (elementType.name().equals("PARAGRAPH")) {
XWPFParagraph pr = (XWPFParagraph) bodyElement;
destDoc.createParagraph();
int pos = destDoc.getParagraphs().size() - 1;
destDoc.setParagraph(pr, pos);
} else if( elementType.name().equals("TABLE") ) {
XWPFTable table = (XWPFTable) bodyElement;
destDoc.createTable();
int pos = destDoc.getTables().size() - 1;
destDoc.setTable(pos, table);
}
}
destDoc.write(out);
}
}
しかし、この方法でも、イメージやスタイルをコピーすることはできません。
そのため、コピーされたドキュメントは元のドキュメントとは異なって見えます。
org.apache.poi.xwpf.usermodel.XWPFRun.addPicture()メソッドにバグがあるようです。
によって追加された画像を含む Docx ドキュメントXWPFRun.addPicture()は、Microsoft Word では開かれません。
