以下是从Open Office Document Format(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 ，以及使用以下命令在命令提示符中编译它 :
javac OpenDocumentParse.java java OpenDocumentParse
以下是example_open_document_presentation.odp文件的快照.
此文档具有以下属性 :
编译程序后，您将获得以下输出.
输出 :
Contents of the document:Apache Tika Apache Tika is a framework for content type detection and content extraction which was designed by Apache software foundation. It detects and extracts metadata and structured text content from different types of documents such as spreadsheets, text documents, images or PDFs including audio or video input formats to certain extent.
