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.

Retrieves a named notation. Only notations declared in the internal DTD subset can be retrieved.

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.
Returns an array of nodes matching a given XPath.
