问题描述 (Problem Description)

如何使用java从ODF中提取内容。

解决方案 (Solution)

以下是使用java从ODF中提取内容的程序。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 ExtractContentFromODF {

public static void main(String[] args) throws Exception {

//detecting the file type

BodyContentHandler handler = new BodyContentHandler();

Metadata metadata = new Metadata();

FileInputStream inputstream = new FileInputStream(new File(

"C:/tika/odfExample.odt"));

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));

}

}

}

输入 (Input)

输出 (Output)Contents of the document: IOWIKI originated from the idea that there exists a

class of readers who respond better to online content and prefer to learn new skills

at their own pace from the comforts of their drawing rooms.

The journey commenced with a single tutorial on HTML in 2006 and elated by the response

it generated, we worked our way to adding fresh tutorials to our repository which now

proudly flaunts a wealth of tutorials and allied articles on topics ranging from

programming languages to web designing to academics and much more.
