如何使用 Apache Tika 跳过页眉和页脚提取

Question

如何使用 apache tika 提取 (pdf,docx,doc,odt) 等不带页眉和页脚的文档。

Answer 1

我用所有文件格式测试了这段代码，有些解析得很好（pdf 和 html），但不适用于 doc、docx、xlsx、xls 格式

import org.apache.tika.exception.TikaException;
import org.apache.tika.io.TikaInputStream;
import org.apache.tika.parser.AutoDetectParser;
import org.apache.tika.parser.html.BoilerpipeContentHandler;
import org.apache.tika.sax.BodyContentHandler;
import org.xml.sax.ContentHandler;
import org.xml.sax.SAXException;
import org.apache.tika.metadata.Metadata;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.net.URL;   

public class NewtikaXpath {
    public static void main(String args[]) throws IOException, SAXException, TikaException {
        AutoDetectParser parser = new AutoDetectParser();
        ContentHandler textHandler = new BodyContentHandler();
        Metadata xmetadata = new Metadata();
        try  (InputStream stream = TikaInputStream.get(new URL("your favourite url"))){
            parser.parse(stream, new BoilerpipeContentHandler(textHandler), xmetadata);
            System.out.println("text:\n" + textHandler.toString());
        }
    }

}

您可以按程序进行。以下是所有 tika 支持的文档的工作方式，包括 docx、pptx、odt pdf

   ParseContext parseContext = new ParseContext();
AutoDetectParser parser = new AutoDetectParser();
ContentHandler contentHandler = new BodyContentHandler();
inputStream = new BufferedInputStream(new FileInputStream(inputFileName));
Metadata metadata = new Metadata();

OfficeParserConfig officeParserConfig = new OfficeParserConfig();
officeParserConfig.setIncludeHeadersAndFooters(false);
parseContext.set(OfficeParserConfig.class, officeParserConfig);

parser.parse(inputStream, contentHandler, metadata, parseContext);
System.out.println(contentHandler.toString());
