Itunes.parse constructor

Itunes.parse(XmlElement element)

Factory method to create an Itunes object from an XmlElement.

This method parses the element and extracts the iTunes metadata values from it to create an Itunes object and returns it.

The author, summary, explicit, title, subtitle, owner, keywords, image, categories, type, newFeedUrl, block, complete, episode, season, duration, and episodeType values are obtained by accessing specific elements or attributes within the element and parsing them accordingly.

Implementation

factory Itunes.parse(XmlElement element) {
  final episodeStr =
      element.findElements('itunes:episode').firstOrNull?.innerText ?? '';
  final seasonStr =
      element.findElements('itunes:season').firstOrNull?.innerText ?? '';
  final durationStr =
      element.findElements('itunes:duration').firstOrNull?.innerText ?? '';
  return Itunes(
    author: element.findElements('itunes:author').firstOrNull?.innerText,
    summary: element.findElements('itunes:summary').firstOrNull?.innerText,
    explicit: parseBoolLiteral(element, 'itunes:explicit'),
