Is it possible to extract text by page for word/pdf files using Apache Tika?

All the documentation I can find seems to suggest I can only extract the entire file's content. But I need to extract pages individual开发者_高级运维ly. Do I need to write my own parser for that? Is there some obvious method that I am missing?

Actually Tika does handle pages (at least in pdf) by sending elements <div><p> before page starts and </p></div> after page ends. You can easily setup page count in your handler using this (just counting pages using only <p>):

public abstract class MyContentHandler implements ContentHandler {
    private String pageTag = "p";
    protected int pageNumber = 0;
    ...
    @Override
    public void startElement (String uri, String localName, String qName, Attributes atts) throws SAXException  {  

        if (pageTag.equals(qName)) {
            startPage();
        }
    }

    @Override
    public void endElement (String uri, String localName, String qName) throws SAXException {  

        if (pageTag.equals(qName)) {
            endPage();
        }
    }

    protected void startPage() throws SAXException {
    pageNumber++;
    }

    protected void endPage() throws SAXException {
    return;
    }
    ...
}

When doing this with pdf you may run into the problem when parser doesn't send text lines in proper order - see Extracting text from PDF files with Apache Tika 0.9 (and PDFBox under the hood) on how to handle this.

You'll need to work with the underlying libraries - Tika doesn't do anything at the page level.

For PDF files, PDFBox should be able to give you some page stuff. For Word, HWPF and XWPF from Apache POI don't really do page level things - the page breaks aren't stored in the file, but instead need to be calculated on the fly based on the text + fonts + page size...

You can get the number of pages in a Pdf using the metadata object's xmpTPg:NPages key as in the following:

Parser parser = new AutoDetectParser();
Metadata metadata = new Metadata();
ParseContext parseContext = new ParseContext();
parser.parse(fis, handler, metadata, parseContext);
metadata.get("xmpTPg:NPages");
