Gets all IP addresses for name from the hosts file.

Creates a new DNS resolver. See Resolv::DNS.new for argument details.

Yields the created DNS resolver to the block, if given, otherwise returns it.

Sets the resolver timeouts. This may be a single positive number or an array of positive numbers representing timeouts in seconds. If an array is specified, a DNS request will retry and wait for each successive interval in the array until a successful response is received. Specifying nil reverts to the default timeouts:

5, second = 5 * 2 / nameserver_count, 2 * second, 4 * second

Example:

dns.timeouts = 3

Closes the DNS resolver.

Gets all IP addresses for name from the DNS resolver.

name can be a Resolv::DNS::Name or a String. Retrieved addresses will be a Resolv::IPv4 or Resolv::IPv6

Returns the namespace URL, if defined, or nil otherwise

e = Element.new("el")
e.add_namespace("ns", "http://url")
e.add_attribute("ns:a", "b")
e.add_attribute("nsx:a", "c")
e.attribute("ns:a").namespace # => "http://url"
e.attribute("nsx:a").namespace # => nil

This method always returns “” for no namespace attribute. Because the default namespace doesn’t apply to attribute names.

> the default namespace does not apply to attribute names

e = REXML::Element.new("el")
e.add_namespace("", "http://example.com/")
e.namespace # => "http://example.com/"
e.add_attribute("a", "b")
e.attribute("a").namespace # => ""

Returns a copy of this attribute
