Extract formatted text from document page

GroupDocs.Parser provides the functionality to extract a formatted text from document page by the getFormattedText(int, FormattedTextOptions) method:

TextReader getFormattedText(int pageIndex, FormattedTextOptions options);

The method returns an instance of TextReader class with an extracted text. FormattedTextOptions has the following constructor:

FormattedTextOptions(FormattedTextMode mode);

FormattedTextMode enumeration has the following members:

Member	Description
Html	HTML format.
Markdown	Markdown format.
PlainText	Plain text format.

TextReader class extends java.io.Reader and adds the following members:

Member	Description
readLine	Reads a line of characters from the text reader and returns the data as a string.
readToEnd	Reads all characters from the current position to the end of the text reader and returns them as one string.

Here are the steps to extract a HTML formatted page text from the document:

Instantiate Parser object for the initial document;
Instantiate FormattedTextOptions with HTML text mode;
Call getFormattedText(int, FormattedTextOptions) method with the page index and obtain TextReader object;
Check if reader isn’t null (formatted text extraction is supported for the document);
Read a text from reader.

The following example shows how to extract a document page text as Markdown text:

// Create an instance of Parser class
try (Parser parser = new Parser(Constants.SampleDocx)) {
    // Check if the document supports formatted text extraction
    if (!parser.getFeatures().isFormattedText()) {
        System.out.println("Document isn't supports formatted text extraction.");
        return;
    }
    // Get the document info
    IDocumentInfo documentInfo = parser.getDocumentInfo();
    // Check if the document has pages
    if (documentInfo.getPageCount() == 0) {
        System.out.println("Document hasn't pages.");
        return;
    }
    // Iterate over pages
    for (int p = 0; p < documentInfo.getPageCount(); p++) {
        // Print a page number 
        System.out.println(String.format("Page %d/%d", p + 1, documentInfo.getPageCount()));
        // Extract a formatted text into the reader
        try (TextReader reader = parser.getFormattedText(p, new FormattedTextOptions(FormattedTextMode.Markdown))) {
            // Print a formatted text from the document
            // We ignore null-checking as we have checked formatted text extraction feature support earlier
            System.out.println(reader.readToEnd());
        }
    }
}
