Method Summary
def \ (that : java.lang.String) : NodeSeq
Projection function. Similar to XPath, use this \ "foo" to get a list of all elements of this sequence that are labelled with "foo". Use \ "_" as a wildcard. Use ns \ "@foo" to get the unprefixed attribute "foo". Use ns \ "@{uri}foo" to get the prefixed attribute "pre:foo" whose prefix "pre" is resolved to the namespace "uri". For attribute projections, the resulting NodeSeq attribute values are wrapped in a Group. There is no support for searching a prefixed attribute by its literal prefix. The document order is preserved.
def \\ (that : java.lang.String) : NodeSeq
projection function. Similar to XPath, use this \\ 'foo to get a list of all elements of this sequence that are labelled with "foo". Use \\ "_" as a wildcard. Use ns \\ "@foo" to get the unprefixed attribute "foo". Use ns \\ "@{uri}foo" to get each prefixed attribute "pre:foo" whose prefix "pre" is resolved to the namespace "uri". For attribute projections, the resulting NodeSeq attribute values are wrapped in a Group. There is no support for searching a prefixed attribute by its literal prefix. The document order is preserved.
def apply (f : (Node) => Boolean) : NodeSeq
def apply (i : Int) : Node
Returns the elements at position `idx`
override def equals (x : Any) : Boolean
structural equality (XXX - this shatters any hope of hashCode equality)
override def iterator : Iterator[Node]
Creates a new iterator over all elements contained in this iterable object.
def length : Int
Returns the length of the sequence.
protected[this] override def newBuilder : Builder[Node, NodeSeq]
Creates a list buffer as builder for this class
def text : java.lang.String
abstract def theSeq : Seq[Node]
override def toString : java.lang.String
Need to override string, so that it's not the Function1's string that gets mixed in.
