TIKA - 提取 MS-Office 文件

---

下面给出的是从 Microsoft Office 文档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.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));
      }
   }
}

将上述代码保存为MSExelParse.java，并使用以下命令从命令提示符进行编译 -

javac MSExcelParse.java
java MSExcelParse 

在这里，我们传递以下示例 Excel 文件。

给定的 Excel 文件具有以下属性 -

执行上述程序后，您将得到以下输出。
