Tika解析器解析word / pdf

Question

我有兴趣将MS Word文档和pdf内容解析为内容及其结构。我应该能够从其内容大致重建文档。将使用什么tika方法来获取页眉，页脚，标题1，标题2，表格结构，段落等。

我在线搜索了解决方案，但找不到准确的答案。其中一些是指Apache POI项目。有人可以建议添加到以下程序的代码 -

public class MSWordParser {
    public static void main(final String[] args) throws IOException, TikaException, SAXException, OpenXML4JException, XmlException {
        BodyContentHandler handler = new BodyContentHandler();
        Metadata metadata = new Metadata();
        FileInputStream inputstream = new FileInputStream(new File("Sample_document.docx"));
        ParseContext pcontext = new ParseContext();
        OOXMLParser msofficeparser = new OOXMLParser ();
        msofficeparser.parse(inputstream, handler, metadata, pcontext);
        System.out.println("Contents of the document:" + handler.toString());
        System.out.println(" " + metadata.get(Metadata.CONTENT_TYPE));
        System.out.println("Sample Word Document"+ metadata.get(TikaCoreProperties.TITLE));
        System.out.println("Metadata of the document:");
        String[] metadataNames = metadata.names();

        for(String name : metadataNames) {
            System.out.println(name + ": " + metadata.get(name));
        }
