Complete XPath 1.0 engine: location paths, axes, node tests, predicates, functions, variables, namespaces, node sets, boolean/number/string conversion, comparison semantics, NaN/infinity/negative zero, document order, context position/size, extension functions, compiled expressions.

Modules

• ast — expression AST types (axes, node tests, steps, operators)
• lexer — tokenizer
• parser — recursive descent parser
• types — XPath value types (node sets, numbers, strings, booleans)
• context — evaluation context (variables, namespaces, functions)
• axes — axis traversal
• functions — core function library (25 XPath 1.0 functions)
• eval — evaluation engine
