opml #
A Dart package for parsing and building OPML documents.
Installing #
Import the package into your Dart code using:
import 'package:opml/opml.dart';
Examples #
Parsing XML #
To parse XML input, use the OpmlDocument.parse(String xmlString) factory:
final xmlString = """
<?xml version='1.0' encoding='UTF-8' ?>
<opml version="1.0">
<head>
<title>Example OPML Export</title>
</head>
<body>
<outline text="World" title="World">
<outline type="rss" text="BBC News - World" xmlUrl="http://feeds.bbci.co.uk/..." />
<outline type="rss" text="World news | The Guardian" xmlUrl="http://feeds.guardian.co.uk/..." />
</outline>
<outline text="Uncategorized" title="Uncategorized" />
</body>
</opml>
""";
final opml = OpmlDocument.parse(xmlString);
Converting to XML #
You can convert an OpmlDocument object to XML by first constructing the object and then calling toXmlString() on it.
final head = OpmlHeadBuilder().title('Example Export').build();
final body = <OpmlOutline>[];
body.add(OpmlOutlineBuilder()
.text('World')
.title('World')
.addChild(OpmlOutlineBuilder()
.type('rss')
.text('BBC News - World')
.title('BBC News - World')
.xmlUrl('http://feeds.bbci.co.uk/news/world/rss.xml')
.build())
.addChild(OpmlOutlineBuilder()
.type('rss')
.text('World news | The Guardian')
.title('World news | The Guardian')
.xmlUrl('http://feeds.guardian.co.uk/theguardian/world/rss')
.build())
.build());
body.add(OpmlOutlineBuilder()
.text('Uncategorized')
.title('Uncategorized')
.build());
final opml = OpmlDocument(
head: head,
body: body,
);
final xml = opml.toXmlString(pretty: true);
print(xml);
