A C# class library for parsing HTML into a searchable, filterable DOM tree
var html = "<html><head></head><body><div>Hello World!</div></body></html>";
var dom = Html.Parse(html,
new ParserOptions()
{
ReplaceNbsp = " ",
TrimText = TrimType.OneTrailingSpace
});
var elemText = dom.Elements.Where(el => el.Text.Contains("Hello")).FirstOrDefault();
// select all child nodes from all DIV tags
var nodes = dom.Elements.Where(el => el.TagName == "div").SelectMany((el, results) => el.Children());
foreach(var elem in dom.Elements.Where(el => el.ClassNames.Contains("button")))
{
var button = elem.AllChildren.First(el => el.TagName == "a");
elem.ReplaceWith(button)
}
In the example above, we are replacing all elements that contain the ClassName "button" with an <a> tag found within each button childNode hierarchy using the AllChildren method.
