def sequenceToXML(children: Seq[Node], pscope: NamespaceBinding, sb: StringBuilder, stripComments: Boolean, decodeEntities: Boolean, preserveWhitespace: Boolean, minimizeTags: Value): Unit
def serialize(x: Node, pscope: NamespaceBinding, sb: StringBuilder, stripComments: Boolean, decodeEntities: Boolean, preserveWhitespace: Boolean, minimizeTags: Value): StringBuilder

Serialize an XML Node to a StringBuilder.

Serialize an XML Node to a StringBuilder.

This is essentially a minor rework of toXML that can't have the same name due to an unfortunate combination of named/default arguments and overloading.

Attributes

use a Writer instead

def sort(md: MetaData): MetaData

returns a sorted attribute list

returns a sorted attribute list

Attributes

def sort(n: Node): Node

Return the node with its attribute list sorted alphabetically (prefixes are ignored)

Return the node with its attribute list sorted alphabetically (prefixes are ignored)

Attributes

def splitName(name: String): (Option[String], String)
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)

Attributes

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: String, s: StringBuilder): StringBuilder

Appends unescaped string to s, amp becomes &amp;, lt becomes &lt; etc..

Appends unescaped string to s, amp becomes &amp;, lt becomes &lt; etc..

Attributes

Returns

'''null''' if ref was not a predefined entity.

Deprecated methods

def toXML(x: Node, pscope: NamespaceBinding, sb: StringBuilder, stripComments: Boolean, decodeEntities: Boolean, preserveWhitespace: Boolean, minimizeTags: Boolean): StringBuilder

Serialize the provided Node to the provided StringBuilder.

Serialize the provided Node to the provided StringBuilder.

Note that calling this source-compatible method will result in the same old, arguably almost universally unwanted, behaviour.
