CONTENT_REGEXP | = | /^\s*(\d+\.?\d*)(;|;\s*url=\s*['"]?(\S*?)['"]?)?\s*$/i |
Matches the content attribute of a meta tag. After the match:
$1:: delay $3:: url |
Parses the delay and url from the content attribute of a meta tag. Parse requires the uri of the current page to infer a url when no url is specified. If a block is given, the parsed delay and url will be passed to it for further processing.
Returns nil if the delay and url cannot be parsed.
# <meta http-equiv="refresh" content="5;url=http://example.com/" /> uri = URI.parse('http://current.com/') Meta.parse("5;url=http://example.com/", uri) # => ['5', 'http://example.com/'] Meta.parse("5;url=", uri) # => ['5', 'http://current.com/'] Meta.parse("5", uri) # => ['5', 'http://current.com/'] Meta.parse("invalid content", uri) # => nil
