''';
final parser = HtmlParser();
var node = parser.parse(htmlString);
parser.query(node, '//div/a@text');
parser.query(
node,
'//div/a/@href|dart.replace(https://,)|dart.substring(0,10)',
);
parser.queryNodes(node, '//tr/td|dart.sublist(0,2)');
const String jsonString = '''
{"author":"Cals Ranna","website":"https://github.com/CalsRanna","books":[{"name":"Hello"},{"name":"World"},{"name":"!"}]}
''';
node = parser.parse(jsonString);
parser.query(node, r'$.author');
parser.query(
node,
r'$.website|dart.replace(https://,)|dart.substring(0,10)',
);
parser.queryNodes(node, r'$.books|dart.sublist(0,2)');
}
Usage #
So far, we have supported:
- some xpath syntax by xpath_selector
- almost all jsonPath syntax by json_path
And seven supported functions list below:
- sublist for
List<HtmlParserNode> - replace for
String - replaceFirst for
String - replaceRegExp for
String - substring for
String - trim for
String - interpolate for
String, use{{string}}to indicate the piped value - match for
String
You should know that in the function, the params CAN NOT be wrapped by ' or ".
And the rule is like //div/a@text|dart.replace(Author,)|dart.replace( ,)|dart.interpolate(作者：{{string}}).
Use | to pipe all rules.
Legacy #
function:will be replaced bydart.in the future.
