TIKA - 提取 MS-Office 檔案

以下是從 Microsoft Office 文件中提取內容和元資料的程式。

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));
      }
   }
}

將上述程式碼另存為 MSExelParse.java，並使用以下命令透過命令提示符對其進行編譯 −

javac MSExcelParse.java
java MSExcelParse 

在此處，我們將傳遞以下示例 Excel 檔案。

給定的 Excel 檔案具有以下屬性 −

在執行上述程式後，將獲得以下輸出。
