XML Formatter Color

The tool accepts an XML document as input and returns two outputs: a pretty-printed XML string and a colorized representation suitable for documentation or testing pipelines. It emphasizes well-formedness and uses deterministic formatting rules so diffs remain stable across runs. This is valuable for developers, data engineers, QA analysts, and DevOps practitioners who work with configuration files, data exchanges, or service payloads. It supports UTF-8 by default and detects encoding when present.
Conceptually, the tool separates concerns: parsing validates structure, formatting applies indentation and line breaks, and colorization assigns distinct visual tokens to elements, attributes, values, comments, and text. The color map can be exported as CSS classes or inline HTML spans, enabling downstream rendering without changing the underlying data. The colorized output is designed for environments that render HTML or syntax-highlighted logs, while the formatted XML remains plain text for diffs and audits.
Unique value lies in combining formatting with token-based colorization in a single pass, producing outputs that are both machine-friendly and human-friendly. Use cases include preparing patch-sized diffs for pull requests, validating inputs against an XML Schema (XSD) when provided, and generating readable XML for integration guides, runbooks, and onboarding. The tool targets software teams, data platforms, IT operations, and developers who frequently exchange XML payloads.
Core features and behaviors include configurable indentation (2–8 spaces), multiple color schemes (e.g., default, high-contrast), optional HTML snippet generation, and optional strict validation. Advanced users can enable attribute wrapping, customize error formatting with line/column info, and choose between compact or expanded formatting modes depending on log length and review needs.
