Release.fromXml constructor

Release.fromXml(
  1. XmlElement xml, {
  2. Language? language,
})

Constructs a Release from the provided XmlElement.

If xml contains language attributes specified for description, then this will try to use the language specified (or English, if null).

Implementation

factory Release.fromXml(XmlElement xml, {Language? language}) {
  language ??= L10n.languages.first;

  String title = xml.findElements('title').first.innerText;

  // Omit the leading `v` of the release version, if any.
  if (title.startsWith('v')) {
    title = title.substring(1);
  }

  final String? description =
      xml
          .findElements('description')
          .firstWhereOrNull(
            (e) => e.attributes.any(
              (p) =>
                  p.name.qualified == 'xml:lang' &&
                  p.value == language?.toString(),
            ),
          )
          ?.innerText ??
      xml.findElements('description').firstOrNull?.innerText;

  final String date = xml.findElements('pubDate').first.innerText;
  final List<ReleaseArtifact> assets =
      xml
          .findElements('enclosure')
          .map((e) => ReleaseArtifact.fromXml(e))
          .toList();

  return Release(
    name: title,
    description: (description?.isEmpty ?? true) ? null : description?.trim(),
    publishedAt: Rfc822ToDateTime.tryParse(date) ?? DateTime.now(),
    assets: assets,
  );
