# Documentation

module Data.AssocList

type XmlTree = NTree XNode #

Rose tree with XML nodes (XNode)

data XNode #

Represents elements

Constructors

XText String | ordinary text (leaf)
XBlob Blob | text represented more space efficient as bytestring (leaf)
XCharRef Int | character reference (leaf)
XEntityRef String | entity reference (leaf)
XCmt String | comment (leaf)
XCdata String | CDATA section (leaf)
XPi QName XmlTrees | Processing Instr with qualified name (leaf) with list of attributes. If tag name is xml, attributes 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

type Attributes = AssocList String String #

Attribute list

used for storing option lists and features of DTD parts

rwnfAttributes :: Attributes -> () #

Evaluate an assoc list of strings

blobToString :: Blob -> String #

stringToBlob :: String -> Blob #

c_ok :: Int #

no error, everything is ok

c_warn :: Int #

data XmlNodeSet #

data type for representing a set of nodes as a tree structure

this structure is e.g. used to repesent the result of an XPath query such that the selected nodes can be processed or selected later in processing a document tree

Constructors
