Implementation Guide

Let’s break down the implementation process into specific features of GroupDocs.Parser.

Feature 1: Check Document for Formatted Text Extraction

Overview: Ensure your document supports formatted text extraction to prevent runtime errors and improve efficiency.

Implementation Steps

Step 3.1: Initialize the Parser class:

import com.groupdocs.parser.Parser;
import com.groupdocs.parser.data.IDocumentInfo;
import com.groupdocs.parser.exceptions.UnsupportedDocumentFormatException;

try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.docx")) {
    if (!parser.getFeatures().isFormattedText()) {
        System.out.println("Document isn't supported for formatted text extraction.");
    }
}

Explanation:

  • getFeatures(): Retrieves document capabilities.
  • isFormattedText(): Checks support for formatted text.

Feature 2: Extract Document Information

Overview: Access vital metadata like page count to inform further processing decisions.

Implementation Steps

Step 3.2: Retrieve and check document information:

import com.groupdocs.parser.Parser;
import com.groupdocs.parser.data.IDocumentInfo;
import com.groupdocs.parser.exceptions.UnsupportedDocumentFormatException;

try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.docx")) {
    IDocumentInfo documentInfo = parser.getDocumentInfo();
    
    if (documentInfo.getPageCount() == 0) {
        System.out.println("Document hasn't any pages.");
    }
}

Explanation:

  • getDocumentInfo(): Provides metadata about the document.
  • getPageCount(): Returns the number of pages.

Feature 3: Extract Formatted Text from Document Pages

Overview: Extract richly-formatted text in Markdown for easy content transformation and reuse.

Implementation Steps

Step 3.3: Iterate through pages to extract formatted text:

import com.groupdocs.parser.Parser;
import com.groupdocs.parser.data.IDocumentInfo;
import com.groupdocs.parser.options.FormattedTextOptions;
import com.groupdocs.parser.options.FormattedTextMode;
import com.groupdocs.parser.data.TextReader;
import com.groupdocs.parser.exceptions.UnsupportedDocumentFormatException;

try (Parser parser = new Parser("YOUR_DOCUMENT_DIRECTORY/sample.docx")) {
    IDocumentInfo documentInfo = parser.getDocumentInfo();
    
    for (int p = 0; p < documentInfo.getPageCount(); p++) {
        try (TextReader reader = parser.getFormattedText(p, new FormattedTextOptions(FormattedTextMode.Markdown))) {
            System.out.println(reader.readToEnd());
        }
    }
}

Explanation:

  • getFormattedText(): Extracts text in specified formats; here, Markdown.
  • FormattedTextOptions: Configures extraction settings.
  • readToEnd(): Reads the entire formatted content of a page.
