select(root)
public
Selects and returns an array with all matching elements, beginning with one
node and traversing through all children depth-first. Returns an empty
array if no match is found.
The root node may be any element in the document, or the document itself.
For example:
selector=HTML::Selector.new"input[type=text]"matches=selector.select(element)matches.eachdo|match|puts"Found text field with name #{match.attributes['name']}"end
# File actionview/lib/action_view/vendor/html-scanner/html/selector.rb, line 455
def select(root)
matches = []
stack = [root]
while node = stack.pop
if node.tag? && subset = match(node, false)
subset.each do |match|
matches << match unless matches.any? { |item| item.equal?(match) }
end
elsif children = node.children
stack.concat children.reverse
end
end
matches
end
