下面给出的是从HTML文档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.html.HtmlParser;
import org.apache.tika.sax.BodyContentHandler;
import org.xml.sax.SAXException;
public class HtmlParse {
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.html"));
ParseContext pcontext = new ParseContext();
//Html parser
HtmlParser htmlparser = new HtmlParser();
htmlparser.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));
}
}
}
将以上代码另存为HtmlParse.java ,并使用以下命令从命令提示符下进行编译-
javac HtmlParse.java
java HtmlParse
下面给出的是example.txt文件的快照。
HTML文档具有以下属性-
如果执行上述程序,它将提供以下输出。
输出–
