# Parser Settings

The parser extracts structured metadata such as title, season, episode and subgroup from RSS item titles.

::: tip
Since v3.1, the source parser for each RSS feed is configured when adding or editing that feed. This page controls the global switch, title parser, language and filters.

## WebUI

- **Enable**: enables RSS parsing.
- **Title parser**: `Classic parser (Stable)` preserves the existing behavior. `Universal parser (Preview)` adds episode ranges, OVAs, movies and mixed collections. The engines never silently fall back to each other.
- **Language**: preferred parser language. Supported values are `zh`, `jp` and `en`.
- **Exclude**: global filter rules. Plain strings and regular expressions are supported.
