GoQuerylike

GoQuerylike is a library for the Go language providing a jQuery-like API for parsing and manipulating HTML documents. It offers CSS selector-based querying, traversal utilities, and methods to read or modify node content and attributes. The library is designed to simplify tasks such as web scraping, data extraction, and template-driven content processing by enabling concise, chainable operations on parsed HTML.

Design and API: It mirrors the jQuery style, with a selector engine to obtain a set of nodes, and chainable methods such as Text(), HTML(), Attr(name), SetAttr, RemoveAttr, AddClass, RemoveClass, Children(), Parents(), Find() for nested queries. It integrates with Go's net/http and io packages, taking an HTML document from a response body or a string and producing a collection of nodes for processing. It does not execute client-side JavaScript, and therefore is intended for static HTML parsing.

Usage: Typical workflows include fetching a page via HTTP, parsing with a document object, selecting elements with a CSS selector, and extracting data or modifying attributes for downstream processing.

Limitations and footprint: As a server-side tool, it operates on static HTML and may not reflect dynamic content generated by JavaScript. It is designed to be lightweight with a small API surface to minimize dependencies.
