Tika 简明教程
TIKA - Extracting ODF
以下是从开放文档格式(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中编译它 -
javac OpenDocumentParse.java
java OpenDocumentParse
以下是对 example_open_document_presentation.odp 文件的快照。
