DOM-based parsing and rendering.
This module requires that all entities be resolved at parsing. If you need to interact with unresolved entities, please use Text.XML.Unresolved. This is the recommended module for most uses cases.
While many of the datatypes in this module are simply re-exported from
Data.XML.Types
, Document
, Node
and Element
are all redefined here to
disallow the possibility of unresolved entities. Conversion functions are
provided to switch between the two sets of datatypes.
For simpler, bidirectional traversal of the DOM tree, see the Text.XML.Cursor module.

Prefixes are not semantically important; they are included only to
simplify pass-through parsing. When comparing names with Eq
or Ord
methods, prefixes are ignored.
The IsString
instance supports Clark notation; see

the OverloadedStrings
language extension for very simple Name

Note: due to the incredible complexity of DTDs, this type only supports external subsets. I've tried adding internal subset types, but they quickly gain more code than the rest of this module put together.
It is possible that some future version of this library might support internal subsets, but I am no longer actively working on adding them.

Since 1.2.1
Entity decoding
decodeXmlEntities :: DecodeEntities Source #
Default implementation of DecodeEntities
, which leaves the
entity as-is. Numeric character references and the five standard
entities (lt, gt, amp, quot, pos) are handled internally by the
parser.
decodeHtmlEntities :: DecodeEntities Source #
HTML4-compliant entity decoder. Handles the additional 248 entities defined by HTML 4 and XHTML 1.
Note that HTML 5 introduces a drastically larger number of entities, and this code does not recognize most of them.
Rendering
data RenderSettings Source #

Default RenderSettings Source # | |
Defined in Text.XML.Stream.Render def :: RenderSettings # |
rsPretty :: RenderSettings -> Bool Source #
rsNamespaces :: RenderSettings -> [(Text, Text)] Source #
Defines some top level namespace definitions to be used, in the form of (prefix, namespace). This has absolutely no impact on the meaning of your documents, but can increase readability by moving commonly used namespace declarations to the top level.
rsAttrOrder :: RenderSettings -> Name -> Map Name Text -> [(Name, Text)] Source #
Specify how to turn the unordered attributes used by the Text.XML module into an ordered list.
rsUseCDATA :: RenderSettings -> Content -> Bool Source #
Determines if for a given text content the renderer should use a CDATA node.
Default: False
Since: 1.3.3
rsXMLDeclaration :: RenderSettings -> Bool Source #
Determines whether the XML declaration will be output.
Default: True
Since: 1.5.1
orderAttrs :: [(Name, [Name])] -> Name -> Map Name Text -> [(Name, Text)] Source #
Convenience function to create an ordering function suitable for
use as the value of rsAttrOrder
. The ordering function is created
from an explicit ordering of the attributes, specified as a list of
tuples, as follows: In each tuple, the first component is the
Name
of an element, and the second component is a list of
attributes names. When the given element is rendered, the
attributes listed, when present, appear first in the given order,
followed by any other attributes in arbitrary order. If an element
does not appear, all of its attributes are rendered in arbitrary
order.
