Default stringizing method to emit standard error message.
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
Creates a new IPv6
address from arg
which may be:
IPv6
returns arg
.
arg
must match one of the IPv6::Regex* constants
Sets the element of which this object is an attribute. Normally, this is not directly called.
Returns this attribute
Sets the parent of this child to the supplied argument.
Must be a Parent
object. If this object is the same object as the existing parent of this child, no action is taken. Otherwise, this child is removed from the current parent (if one exists), and is added to the new parent.
The parent added
the document this child belongs to, or nil if this child
belongs to no document
This method returns a list of notations that have been declared in the internal DTD
subset. Notations in the external DTD
subset are not listed.

Evaluates to the document to which this element belongs, or nil if this element doesn’t belong to a document.
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.
Get an array of all CData
children. IMMUTABLE
Get an array of all Comment
children. IMMUTABLE
Returns the number of attributes the owning Element
contains.
doc = Document "<a x='1' y='2' foo:x='3'/>" doc.root.attributes.length #-> 3
Evaluates whether the given string matches an entity definition, returning true if so, and false otherwise.
A predicate filters a node-set with respect to an axis to produce a new node-set. For each node in the node-set to be filtered, the PredicateExpr is evaluated with that node as the context node, with the number of nodes in the node-set as the context size, and with the proximity position of the node in the node-set with respect to the axis as the context position; if PredicateExpr evaluates to true for that node, the node is included in the new node-set; otherwise, it is not included.
A PredicateExpr is evaluated by evaluating the Expr and converting the result to a boolean. If the result is a number, the result will be converted to true if the number is equal to the context position and will be converted to false otherwise; if the result is not a number, then the result will be converted as if by a call to the boolean function. Thus a location path para is equivalent to para.
