Aspose.HTML for Python via .NET is an advanced HTML processing API that enables Python developers to create, modify, extract data, merge, and convert HTML documents without relying on external tools or browsers. Fully cross‑platform and suitable for 32-bit or 64-bit Python applications, the library supports major formats such as HTML, XHTML, MHTML, EPUB, SVG, XML, and Markdown, while rendering output to PDF, DOCX, XPS, and multiple image formats. The API integrates the full HTML Document Object Model (DOM) with support for CSS, HTML Canvas, SVG, XPath, and JavaScript, enabling detailed manipulation of document content, structure, and styling. It provides rich capabilities for data extraction, navigation, merging, high‑fidelity document conversion, and web‑based data processing, making it a powerful solution for Python developers building content automation systems, digital publishing workflows, and document-processing applications.

Features

HTML Document Creation, Editing & Navigation

• Create HTML from scratch.
• Load HTML from files, URLs, streams, or strings.
• Add, replace, or remove nodes in the DOM.
• Edit XHTML, MHTML, Markdown, EPUB, and HTML files.
• Extract and edit CSS styling information.
• Navigate documents using XPath queries or CSS selectors.
• Work with HTML Canvas, SVG, JavaScript, and W3C‑based DOM.
• Manage embedded images, tables, and page structure. Format Conversion Convert HTML and related formats into many file types, including:
• PDF, DOCX, XPS
• JPEG, PNG, BMP, TIFF, GIF
• Markdown (MD)
• MHTML, XHTML
• EPUB → PDF/DOCX/PNG/JPG
• SVG → PNG/JPEG/PDF The conversion process is reliable and requires only a few lines of code, enabling fast document transformation within Python environments. Markdown Support
• Implement Markdown to HTML converters and reverse.
• Convert MD to PDF, DOCX, images, or HTML.
• Add Markdown elements programmatically (links, tables, code blocks, lists, headers, images, etc.). EPUB & MHTML Support
• Load EPUB and MHTML files.
• Convert them to PDF, DOCX, raster images, and more. Merging Capabilities
• Merge HTML, MHTML, EPUB, and Markdown files.
• Combine documents into multi-page PDF, XPS, DOCX, TIFF, and image formats. Web Content Extraction
• Extract images, SVG files, tables, and structured content from websites.
• Save files directly from URLs.
• Extract text or HTML elements via CSS selectors and XPath. Data Extraction
• Build custom data extraction solutions using the W3C‑based DOM.
• Inspect, parse, and filter HTML content from web pages.
• Retrieve structured content (tables, headings, links, etc.). High‑Fidelity Rendering
• Render multiple documents at once.
• Convert HTML to fixed-layout formats while preserving layout accuracy.
• Apply headers, footers, and page‑setup options for PDF generation.
