Description
Streaming parser for the OPML 2.0 standard.
The parser tries to be as lenient as possible. All functions may throw an OpmlException.
- parseOpml :: MonadCatch m => ConduitM Event o m (Maybe Opml)
- parseOpmlHead :: MonadCatch m => ConduitM Event o m (Maybe OpmlHead)
- parseOpmlOutline :: MonadCatch m => ConduitM Event o m (Maybe (Tree OpmlOutline))
- data OpmlException
Parsers
parseOpml :: MonadCatch m => ConduitM Event o m (Maybe Opml) Source #
Parse the top-level <opml> element.
parseOpmlHead :: MonadCatch m => ConduitM Event o m (Maybe OpmlHead) Source #
Parse the <head> section.
This function is more lenient than what the standard demands on the following points:
- each sub-element may be repeated, in which case only the first occurrence is taken into account;
- each unknown sub-element is ignored.
parseOpmlOutline :: MonadCatch m => ConduitM Event o m (Maybe (Tree OpmlOutline)) Source #
Parse an <outline> section.
The value of type attributes are not case-sensitive, that is type="LINK" has the same meaning as type="link".
