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
This method retrieves the system identifier identifying the document’s DTD

Evaluates to an Array containing the prefixes (names) of all defined namespaces at this context node.
doc = Document.new("<a xmlns:x='1' xmlns:y='2'><b/><c xmlns:z='3'/></a>") doc.elements['//b'].prefixes # -> ['x', 'y']
Get an array of all Instruction children. IMMUTABLE
Returns an Array of Element children. An XPath may be supplied to filter the children. Only Element children are returned, even if the supplied XPath matches non-Element children.
doc = Document.new '<a>sean<b/>elliott<c/></a>' doc.root.elements.to_a #-> [ <b/>, <c/> ] doc.root.elements.to_a("child::node()") #-> [ <b/>, <c/> ] XPath.match(doc.root, "child::node()") #-> [ sean, <b/>, elliott, <c/> ]
Returns an array of Strings containing all of the prefixes declared by this set of # attributes. The array does not include the default namespace declaration, if one exists.
doc = Document.new("<a xmlns='foo' xmlns:x='bar' xmlns:y='twee' "+ "z='glorp' p:k='gru'/>") prefixes = doc.root.attributes.prefixes #-> ['x', 'y']
Evaluates to the unnormalized value of this entity; that is, replacing all entities – both %ent; and &ent; entities. This differs from +value()+ in that value only replaces %ent; entities.
Returns the value of this entity unprocessed – raw. This is the normalized value; that is, with all %ent; and &ent; entities intact
Returns this entity as a string. See write().
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.
