module Data.AssocList

type XmlTree = NTree XNode

type XmlNavTrees = [NTZipper XNode]

List of navigatable rose trees with XML nodes

data XNode

Represents elements

Constructors

XText String

ordinary text (leaf)

XBlob Blob

text represented more space efficient as bytestring (leaf)

XPi QName XmlTrees

Processing Instr with qualified name (leaf) with list of attributes. If tag name is xml, attributs are "version", "encoding", "standalone", else attribute list is empty, content is a text child node

XTag QName XmlTrees

tag with qualified name and list of attributes (inner node or leaf)

XDTD DTDElem Attributes

DTD element with assoc list for dtd element features

XAttr QName

attribute with qualified name, the attribute value is stored in children

XError Int String

error message with level and text
