Let’s break down the example into multiple steps:

Step 1: Create Parser Settings with External Resource Handler

Instantiate ParserSettings and pass an instance of Handler to handle external resources:

ParserSettings settings = new ParserSettings(new Handler());

Step 2: Instantiate Parser with Settings

Create an instance of Parser by providing the file path and ParserSettings:

using (Parser parser = new Parser("YourSampleFile.docx", settings))
{
    // Your code goes here
}

Step 3: Extract Images from HTML Document

Use the GetImages method to extract images from the document:

IEnumerable<PageImageArea> images = parser.GetImages();

Step 4: Iterate and Process Extracted Images

Iterate over the extracted images and perform desired operations, such as printing the image type:

foreach (PageImageArea image in images)
{
    Console.WriteLine(image.FileType);
}

Conclusion

GroupDocs.Parser for .NET simplifies the process of handling external resources within documents, enabling efficient content extraction and manipulation in C# applications.
