def appendEscapedQuoted(s: String, sb: StringBuilder): StringBuilder

Appends "s" and escapes and " i s with "

Appends "s" and escapes and " i s with "

def appendQuoted(s: String, sb: StringBuilder): StringBuilder

Appends "s" if string s does not contain ", 's' otherwise.

Appends "s" if string s does not contain ", 's' otherwise.

def checkAttributeValue(value: String): String

Returns '''null''' if the value is a correct attribute value, error message if it isn't.

Returns '''null''' if the value is a correct attribute value, error message if it isn't.

def collectNamespaces(nodes: Seq[Node]): Set[String]

Returns a set of all namespaces used in a sequence of nodes and all their descendants, including the empty namespaces.

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[String]): Unit

Adds all namespaces in node to set.

Adds all namespaces in node to set.

final def escape(text: String): String

Escapes the characters < > & and " from string.

Escapes the characters < > & and " from string.

final def escape(text: String, s: StringBuilder): StringBuilder

Appends escaped string to s.

Appends escaped string to s.

def getName(s: String, index: Int): String
def hashCode(pre: String, label: String, attribHashCode: Int, scpeHash: Int, children: Seq[Node]): Int

Returns a hashcode for the given constituents of a node

Returns a hashcode for the given constituents of a node

def parseCharRef(ch: () => Char, nextch: () => Unit, reportSyntaxError: String => Unit, reportTruncatedError: String => Unit): String

See [66]

 CharRef ::= "&amp;#" '0'..'9' {'0'..'9'} ";"
           | "&amp;#x" '0'..'9'|'A'..'F'|'a'..'f' { hexdigit } ";"

See [66]

final def prefix(name: String): Option[String]

Returns prefix of qualified name if any.

Returns prefix of qualified name if any.

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.

Todo:

use a Writer instead

def sort(md: MetaData): MetaData

returns a sorted attribute list

returns a sorted attribute list

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)

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.

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..

Returns:

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

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.
