Struct Lexer 

pub struct Lexer<'a> { /* private fields */ }

XPath 1.0 expression tokenizer.

The lexer processes an XPath expression string and produces a sequence of Tokens. It handles the disambiguation rules from XPath 1.0 section 3.7 to correctly distinguish between operators and name tests for *, and between function names, node type tests, axis names, and plain name tests.

Examples

use xmloxide::xpath::lexer::Lexer;

let mut lexer = Lexer::new("child::p[@class='intro']");
let tokens = lexer.tokenize().unwrap();

Implementations

impl<'a> Lexer<'a>

pub fn new(input: &'a str) -> Self

Creates a new lexer for the given XPath expression string.

pub fn tokenize(&mut self) -> Result<Vec<Token>, XPathError>

Tokenizes the entire input expression into a sequence of tokens.

Applies the XPath 1.0 disambiguation rules (section 3.7) to correctly classify tokens based on their context.

Errors

Returns XPathError if the input contains an invalid token, such as an unterminated string literal or an unexpected character.
