ABBYY OCR SDK in Python: Using xml:writeFormatting (2026)

ABBYY OCR SDK is a powerful tool for converting images of text into machine-readable formats. One of its key features is the ability to retain text formatting in the output XML. In this guide, we'll explore how to use the xml:writeFormatting parameter in Python to maintain the original text formatting when processing images with ABBYY OCR SDK.

Key Takeaways

• Learn how to set up ABBYY OCR SDK in Python for XML output.
• Understand the role of xml:writeFormatting in preserving text layout.
• Step-by-step code implementation for processing images.
• Common troubleshooting tips for ABBYY OCR SDK.
• Best practices for handling formatted text output in XML.

In this tutorial, you will learn how to leverage the ABBYY OCR SDK to convert images to XML while retaining the original text formatting. This is particularly useful for documents where layout and formatting are crucial, such as legal documents, scientific papers, or any text where the presentation is as important as the content. By the end of this guide, you'll be able to implement a Python solution that effectively uses the xml:writeFormatting parameter, ensuring your XML outputs maintain the necessary formatting.

Prerequisites

• Basic understanding of Python programming.
• An active subscription to ABBYY OCR SDK.
• ABBYY Cloud OCR SDK application ID and password.
• Python installed on your machine (preferably version 3.8 or higher).
• Familiarity with XML and its structure.

Step 1: Install Required Python Packages

Before starting, ensure you have the necessary Python packages installed. The key package for this task is the ABBYY SDK's client library.

pip install abbyy-sdk

This package will help you communicate with the ABBYY OCR service from your Python application.

Step 2: Set Up Your ABBYY OCR SDK Client

Initialize the OCR engine with your application credentials. This step is crucial as it authenticates your requests to the ABBYY cloud service.

from abbyy_sdk import CloudOCR

ocr_engine = CloudOCR(application_id='your_application_id', password='your_password')

Replace your_application_id and your_password with your actual ABBYY Cloud OCR application ID and password.

Step 3: Prepare Your Image for Processing

Open the image file you wish to process. This image should be in a format supported by ABBYY OCR, such as JPG or PNG.

jpg = open('pic16.JPG', 'rb')
file = {jpg.name: jpg}

Ensure that the image is clear and well-aligned to improve the OCR accuracy.

Step 4: Process the Image with xml:writeFormatting

Use the process_and_download method to convert the image to XML while retaining the formatting. This is done by setting exportFormat to include xml:writeFormatting=true.

result = ocr_engine.process_and_download(file, 
    exportFormat='xml&xml:writeFormatting=true', language='English')

for format, content in result.items():
    with open('converted.xml', 'wb') as output_file:
        output_file.write(content)

This code will create an XML file with the same formatting as the original document.

Step 5: Verify the Output

Open the converted.xml file to ensure the text and formatting have been correctly preserved. You can use any XML viewer to inspect the structure and content.

Look for elements that represent formatting, such as paragraphs and text styles, to confirm the successful application of xml:writeFormatting.

Common Errors/Troubleshooting

Here are some common issues you might encounter and their solutions:

• Authentication Error: Double-check your application ID and password. Ensure they're correctly entered and the account is active.
• Unsupported File Format: Make sure the image is in a supported format (e.g., JPG, PNG).
• Output Format Error: Ensure that the exportFormat string is correctly formatted.
• Formatting Not Preserved: Verify that xml:writeFormatting=true is included in the export format.

Conclusion

By following these steps, you can efficiently use the ABBYY OCR SDK in Python to convert images to XML while maintaining their formatting. This guide provides a comprehensive approach to using the xml:writeFormatting parameter, ensuring that your document conversions are both accurate and reflective of the original layout. Proper implementation of these techniques will greatly enhance the usability and presentation of your converted documents.
