CRegularExpressionValidator

util · extends CValidator

Full-value JavaScript RegExp validation with exact append-prefix Intermediate. Supports literals, dot, classes, ordinary/noncapturing groups, alternatives, greedy/lazy ?, *, + and {m,n}, and optional outer ^/$ anchors. Uses UTF-16 matching (without u/v). Flags i/s work normally; d/g/m/y do not change full-value matching. Lookarounds, backreferences, boundary assertions, named groups, scoped modifiers and legacy identity/octal escapes are rejected. Compilation is bounded to 4096 states, 64 nested groups and repeat counts 1024.
