DOM parsing

DOM parsing converts an HTML or XML source code string into a structured, in-memory Document Object Model (DOM) tree, enabling programmatic access and manipulation.

DOM parsing is the critical process where a browser or application transforms raw markup (like an HTML file) into a hierarchical tree structure: the DOM. This tree consists of interconnected nodes—elements, attributes, and text—that represent the document’s content and structure. For example, the JavaScript `DOMParser.parseFromString()` method or setting `Element.innerHTML` triggers this mechanism. Once parsed, developers leverage the DOM API to efficiently traverse, modify, or extract data from specific nodes, such as targeting an element by its ID or class for dynamic updates.
