Method Summary
def appendEscapedQuoted (s : java.lang.String, sb : StringBuilder) : StringBuilder
Appends "s" and escapes and " i s with \"
def appendQuoted (s : java.lang.String, sb : StringBuilder) : StringBuilder
Appends "s" if string s does not contain ", 's' otherwise.
def appendQuoted (s : java.lang.String) : java.lang.String
def checkAttributeValue (value : java.lang.String) : java.lang.String
Returns null if the value is a correct attribute value, error message if it isn't.
def collectNamespaces (nodes : Seq[Node]) : Set[java.lang.String]
Returns a set of all namespaces used in a sequence of nodes and all their descendants, including the empty namespaces.
def collectNamespaces (n : Node, set : Set[java.lang.String]) : Unit
Adds all namespaces in node to set.
final def escape (text : java.lang.String, s : StringBuilder) : StringBuilder
Appends escaped string to s.
final def escape (text : java.lang.String) : java.lang.String
Escapes the characters < > & and " from string.
def getName (s : java.lang.String, index : Int) : java.lang.String
def hashCode (pre : java.lang.String, label : java.lang.String, attribHashCode : Int, scpeHash : Int, children : Seq[Node]) : Int
Returns a hashcode for the given constituents of a node
implicit def implicitSbToString (sb : StringBuilder) : java.lang.String
def parseAttributeValue (value : java.lang.String) : Seq[Node]
new
def parseCharRef (ch : () => Char, nextch : () => Unit, reportSyntaxError : (java.lang.String) => Unit) : java.lang.String 
     CharRef ::= "&#" '0'..'9' {'0'..'9'} ";"
               | "&#x" '0'..'9'|'A'..'F'|'a'..'f' { hexdigit } ";"
final def prefix (name : java.lang.String) : Option[java.lang.String]
Returns prefix of qualified name if any.
def sequenceToXML (children : Seq[Node], pscope : NamespaceBinding, sb : StringBuilder, stripComments : Boolean) : Unit
def sort (n : Node) : Node
returns the node with its attribute list sorted alphabetically (prefixes are ignored)
def sort (md : MetaData) : MetaData
returns a sorted attribute list
def toXML (x : Node, pscope : NamespaceBinding, sb : StringBuilder, stripComments : Boolean, decodeEntities : Boolean, preserveWhitespace : Boolean, minimizeTags : Boolean) : StringBuilder
def trim (x : Node) : Node
trims an element - call this method, when you know that it is an element (and not a text node) so you know that it will not be trimmed away. With this assumption, the function can return a Node, rather than a Seq[Node]. If you don't know, call trimProper and account for the fact that you may get back an empty sequence of nodes. precondition: node is not a text node (it might be trimmed)
def trimProper (x : Node) : Seq[Node]
trim a child of an element. Attribute values and Atom nodes that are not Text nodes are unaffected.
final def unescape (ref : java.lang.String, s : StringBuilder) : StringBuilder
Appends unescaped string to s, amp becomes & lt becomes < etc..
