Returns the path from an FTP
URI
.
RFC 1738 specifically states that the path for an FTP
URI
does not include the / which separates the URI
path from the URI
host. Example:
ftp://ftp.example.com/pub/ruby
The above URI
indicates that the client should connect to ftp.example.com then cd pub/ruby from the initial login directory.
If you want to cd to an absolute directory, you must include an escaped / (%2F) in the path. Example:
This method will then return “/pub/ruby”
This is used as a predicate, and ought to be called first.
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:
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
Returns a copy of this attribute
Make a copy of this object
Examples
c = CData.new( "Some text" ) d = c.clone d.to_s # -> "Some text"
Should be obvious
Creates a shallow copy of self.
d = Document.new "<a><b/><b/><c><d/></c></a>" new_a = d.root.clone puts new_a # => "<a/>"
Evaluates to true
if whitespace is respected for this element. This is the case if:
Neither :respect_whitespace
nor :compress_whitespace
has any value
The context has :respect_whitespace
set to :all
or an array containing the name of this element, and :compress_whitespace
isn’t set to :all
or an array containing the name of this element.
The evaluation is tested against expanded_name
, and so is namespace sensitive.
Evaluates to the URI
for a prefix, or the empty string if no such namespace is declared for this element. Evaluates recursively for ancestors. Returns the default namespace, if there is one.
the prefix to search for. If not supplied, returns the default namespace if one exists
the namespace URI
as a String, or nil if no such namespace exists. If the namespace is undefined, returns an empty string
doc = Document.new("<a xmlns='1' xmlns:y='2'><b/><c xmlns:z='3'/></a>") b = doc.elements['//b'] b.namespace # -> '1' b.namespace("y") # -> '2'
Returns true
if there are no Element
children, false
otherwise
