下面给出的是从开放办公文档格式(ODF)中提取内容和元数据的程序。
import java.io.File; import java.io.FileInputStream; import java.io.IOException; import org.apache.tika.exception.TikaException; import org.apache.tika.metadata.Metadata; import org.apache.tika.parser.ParseContext; import org.apache.tika.parser.odf.OpenDocumentParser; import org.apache.tika.sax.BodyContentHandler; import org.xml.sax.SAXException; public class OpenDocumentParse { public static void main(final String[] args) throws IOException,SAXException, TikaException { //detecting the file type BodyContentHandler handler = new BodyContentHandler(); Metadata metadata = new Metadata(); FileInputStream inputstream = new FileInputStream(new File("example_open_document_presentation.odp")); ParseContext pcontext = new ParseContext(); //Open Document Parser OpenDocumentParser openofficeparser = new OpenDocumentParser (); openofficeparser.parse(inputstream, handler, metadata,pcontext); System.out.println("Contents of the document:" + handler.toString()); System.out.println("Metadata of the document:"); String[] metadataNames = metadata.names(); for(String name : metadataNames) { System.out.println(name + " : " + metadata.get(name)); } } }
将上述代码保存为OpenDocumentParse.java,并使用以下命令在命令提示符下编译它 -
javac OpenDocumentParse.java java OpenDocumentParse
下面给出的是 example_open_document_presentation.odp 文件的快照。
