XSLT Builder

Purpose & User Intent: The XSLT Builder is a developer-oriented tool that transforms XML documents using XSLT stylesheets. It helps data engineers, integrators, and developers create, test, and debug XML-to-output pipelines without local installations. Typical users include API engineers, data teams, and software integrators who need to validate transformations against sample XML data.
Core Logic & Features: The tool applies an XSLT stylesheet to an input XML document using a built-in processor configured for XSLT 1.0/2.0/3.0 as selected. Required features include an XML input validator, an XSLT editor, parameter support, and a live transformed-output preview. Advanced features include parameterized transforms, extension functions, multiple output methods (XML, HTML, text), and batch processing of multiple samples. Rules include well-formed XML input, stylesheet well-formedness, and compatibility checks between stylesheet and processor version.
Inputs & Outputs: Inputs: xml_input (string), xsl_input (string), params (object of key=value pairs), xslt_version (1.0/2.0/3.0), base_uri (string, optional). Outputs: transformed_output (string), diagnostics (object with errors/warnings), and export_options (string/preset). Validation ensures XML well-formedness, stylesheet validity, and runtime errors are captured without crashing.
Algorithms & Calculations: Uses standard XSLT processing: load XML, apply stylesheet, resolve parameters, render result tree, and serialize according to the selected output method. Error handling provides location hints and diagnostic codes. No UI logic is described; the tool is designed for embedding into pipelines or IDE workflows.
Error & Edge Cases: Invalid XML or XSLT raises structured diagnostics with line/column when available. Missing optional inputs default to safe values. Large inputs may be streamed where supported; memory usage is managed by the chosen processor. External data retrieval is optional and guarded by configuration.
Industry/Region & Localization: Respects XML encoding (UTF-8 by default) and supports common locales for text output. Suitable for enterprise data interchange and integration tasks across regions. Assumptions & Exclusions: Assumes text-based inputs; does not render UI or client-side behavior.
