xpath_selector
An XPath selector for locating Html and Xml elements
English | 中文文档
Easy to use
You have three ways to do XPath queries
final html = '''<html><div></div></html>''';
final htmlDom = parse(htmlString).documentElement!;
final xml = '''<root><child></child></root>''';
final xmlRoot = XmlDocument.parse().rootElement;
// Create by html string
final result1 = XPath.html(html).query('//div');
final result2 = XPath.xml(html).query('//child');
// Or through the dom of the HTML or Xml package
final result3 = XPath.htmlElement(htmlDom).query('//div');
final result4 = XPath.xmlElement(xmlRoot).query('//child');
// Or query directly through element
final result5 = htmlDom.queryXPath('//div');
final result6 = xmlRoot.queryXPath('//child');
// Get all nodes of query results
print(result1.elements);
// Get the first node of query results
print(result1.element);
// Get all properties of query results
print(result1.attrs);
// Get the first valid property of the query result (not null)
print(result1.attr);
