Parse Pages Using Templates

Introduction

In this tutorial, we’ll delve into using GroupDocs.Parser for .NET to extract data from documents efficiently. GroupDocs.Parser is a powerful library that enables parsing various document formats like PDF, DOCX, PPTX, and more. We’ll focus on parsing pages using templates, which allows precise extraction of specific content such as barcodes.

Prerequisites

Before we begin, ensure you have the following set up:

• GroupDocs.Parser for .NET Library: You can download it here.
• Development Environment: Visual Studio or any .NET-compatible IDE.
• Sample Document: Have a document with content you want to parse.

Import Namespaces

Start by including necessary namespaces in your C# project:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using GroupDocs.Parser.Data;
using GroupDocs.Parser.Templates;

Step 1: Define a Barcode Field

To extract a barcode, define a TemplateBarcode object. Specify the location (Rectangle) and type of the barcode.

TemplateBarcode barcode = new TemplateBarcode(
    new Rectangle(new Point(405, 55), new Size(100, 50)),
    "QR");

Step 2: Create a Template

Combine the barcode (or other fields) into a Template object.

Template template = new Template(new TemplateItem[] { barcode });

Step 3: Instantiate the Parser

Create an instance of Parser and specify the document path you want to parse.

using (Parser parser = new Parser("YourSampleFile.docx"))
{
    // Iterate over document pages using the template
    foreach (DocumentPageData data in parser.ParsePagesByTemplate(template))
    {
        // Print the page index
        Console.WriteLine("Page: " + data.PageIndex);
        // Print extracted data
        for (int i = 0; i < data.Count; i++)
        {
            Console.Write(data[i].Name + ": ");
            PageBarcodeArea area = data[i].PageArea as PageBarcodeArea;
            Console.WriteLine(area == null ? "Not a template barcode field" : area.Value);
        }
    }
}
