TIKA提取MS Office文件
下麵給出的程序是用於從Microsoft Office文檔中提取內容和元數據。
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.microsoft.ooxml.OOXMLParser; import org.apache.tika.sax.BodyContentHandler; import org.xml.sax.SAXException; public class MSExcelParse { public static void main(final String[] args) throws IOException, TikaException { //detecting the file type BodyContentHandler handler = new BodyContentHandler(); Metadata metadata = new Metadata(); FileInputStream inputstream = new FileInputStream(new File("example_msExcel.xlsx")); ParseContext pcontext = new ParseContext(); //OOXml parser OOXMLParser msofficeparser = new OOXMLParser (); msofficeparser.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)); } } }
保存上述代碼保存為MSExelParse.java,並通過使用下麵的命令從命令提示編譯:
javac MSExcelParse.java java MSExcelParse
下麵給出的是 example_msExcel.xlsx 文件的快照
給定的 Excel 文件具有如下性質:
執行上述程序後,將得到下麵的輸出。
