Fast Regex-Based DOM Parser

dom-parser is a lightweight, zero-dependency library for parsing HTML and XML documents into a DOM-like structure using regular expressions. It provides a subset of standard DOM API methods like `getElementById`, `getElementsByClassName`, and `getElementsByTagName`, along with common node properties such as `innerHTML` and `textContent`. The current stable version is 1.1.5. Due to its regexp-based parsing, it is notably fast and compact, making it suitable for environments where full-fledged, specification-compliant DOM parsing (like `jsdom` or browser DOMParser) is overkill or too resource-intensive. Its main differentiator is performance and minimal footprint by leveraging regexps, though this approach might have limitations with highly malformed or complex HTML structures compared to state-machine parsers.
