NativeElixirPdfUtilities.HtmlToPdf.HtmlParser (native_elixir_pdf_utilities v0.5.1)

View Source

Strict HTML parser for the native HTML-to-PDF renderer.

Supports a strict subset of document-oriented HTML: structural html/head/body/style tags, paragraphs, headings, inline emphasis/color containers, div containers for flex/grid layouts, lists, links, tables, images, and CSS-targeting attributes. Unsupported or malformed markup returns an error instead of guessing at browser behavior.
