Online XML Parser

The tool ingests XML, checks well-formedness, and optionally validates against an XSD schema to ensure structural correctness. It then maps XML nodes, attributes, and text into a JSON-like structure or a navigable tree, enabling downstream processing. Namespace prefixes are preserved and repeated elements are collected as arrays to reflect the data model. Users can request a subset via a node_selector to focus on relevant sections. The output supports compact JSON or human-readable pretty-printed JSON for auditing. The approach is designed for developers and data engineers who integrate XML data into APIs, databases, or data pipelines. It balances strict validation with flexible mapping, making it suitable for configuration data, responses, and feed payloads where deterministic parsing matters. The tool emphasizes deterministic mappings of attributes (prefixed with @) and text content (mapped to #text) to avoid ambiguity in downstream consumers. It also provides clear error traces when parsing fails, including line and column information when available, enabling rapid debugging. Overall value lies in reliable XML ingestion, predictable JSON conversion, and robust error visibility for cross-system data exchange.
