Working with HTML Documents in Python – Create, Edit, and Save HTML

The Working with HTML Documents section explains how to create, load, edit, and save documents with Aspose.HTML for Python via .NET. These articles focus on document-level operations with the HTML Document Object Model (DOM), CSS, and linked resources.

Use HTMLDocument to create or load HTML, access and modify the DOM, and save the result with save(). Use the appropriate conversion API instead when the required output is PDF, DOCX, XPS, or a raster image.

Choose a Document Workflow

• Create or Load a Document in Python – create an empty HTML document or load HTML from a file, URL, string, or stream; learn how SVG documents are loaded and when MHTML or EPUB conversion APIs are required.
• Edit an HTML Document in Python – access DOM nodes, create or remove elements, update attributes and content, and edit inline or internal CSS.
• Save an HTML Document in Python – save the current DOM as HTML, MHTML, or Markdown, and save a standalone SVG document.
• Save HTML with Resources in Python – save linked CSS and images to a selected folder or embed them in one HTML file.

Typical Python HTML Document Workflow

Most document-processing tasks follow the same sequence:

1. Identify whether the HTML source is a local file, URL, string, stream, or a document created from scratch.
2. Create or load an HTMLDocument and access its DOM tree.
3. Read or modify elements, attributes, text, CSS, and linked resources.
4. Save the document with HTMLDocument.save() and configure save options when linked resources require special handling.
5. Use a converter instead of save() when the required result is PDF, DOCX, XPS, or a raster image.

Saving preserves or serializes HTML and its resources. Conversion renders or transforms the source into another output format. Edit the DOM or CSS before either operation when the output must include those changes.
