Key Features of Aspose.HTML for Python via .NET

Aspose.HTML for Python via .NET combines DOM-based document processing with conversion and rendering APIs. Python applications can create, load, inspect, edit, save, and convert HTML-related documents and work with web technologies such as CSS, SVG, JavaScript, and HTML Canvas.

Use HTMLDocument for document and DOM operations, selector or XPath APIs for navigation and extraction, and the Converter class for common format conversions. Save and rendering options provide additional control over the output.

Document Manipulation

Aspose.HTML for Python via .NET can create, load, edit, and save HTML and related documents without opening a browser interface.

• Create or load an HTML document from a file, URL, stream, or HTML string.
• Edit an HTML document by creating, updating, removing, or replacing DOM nodes and attributes.
• Save an HTML document together with associated resources or save it as MHTML or Markdown.
• Apply sandbox restrictions when processing HTML that should not load or execute selected resource types.

Navigation and Data Extraction

The DOM API provides several ways to locate and inspect content in a loaded document:

• Navigate parent, child, and sibling relationships or use traversal interfaces to move through the document tree.
• Select elements by tag name, class, or ID.
• Use query_selector() and query_selector_all() with CSS selector expressions.
• Use evaluate() to execute XPath expressions against HTML or XML documents.
• Extract text, attributes, links, images, SVG elements, and other content selected from the DOM.

See Data Extraction for navigation and resource extraction workflows.

Conversion and Rendering

Aspose.HTML for Python via .NET supports conversion workflows for HTML, XHTML, SVG, MHTML, EPUB, and Markdown sources. Depending on the source and API, output can include HTML, MHTML, Markdown, PDF, XPS, DOCX, and raster images.

The Supported File Formats table distinguishes input formats from output-only formats. Fine-Tuning Converters explains the lower-level rendering APIs and output devices.

Convert HTML to PDF in Python

The verified example below converts document.html to output.pdf:

1. Import the conversion and saving modules.
2. Create default PdfSaveOptions for PDF output.
3. Call Converter.convert_html() with the source file, save options, and output path.

# Convert HTML to PDF in Python

import aspose.html.converters as conv
import aspose.html.saving as sav

# Convert HTML to PDF
conv.Converter.convert_html("document.html", sav.PdfSaveOptions(), "output.pdf")

For source-specific workflows and save options, open Converting Between Formats.
