|XML editing filters|
Applies some Canonical XML rules to the nodes of a tree.
The rule differ slightly for canonical XML and XPath in handling of comments
Note: This is not the whole canonicalization as it is specified by the W3C Recommendation. Adding attribute defaults or sorting attributes in lexicographic order is done by the transform function of module Text.XML.HXT.Validator.Validation. Replacing entities or line feed normalization is done by the parser.
Not implemented yet:
canonicalize tree and remove comments and <?xml ... ?> declarations
Canonicalize a tree for XPath Comment nodes are not removed
|Collects sequences of child XText nodes into one XText node.|
Applies collapseXText recursively.

filter for indenting a document tree for pretty printing.
the tree is traversed for inserting whitespace for tag indentation.
whitespace is only inserted or changed at places, where it isn't significant, is's not inserted between tags and text containing non whitespace chars.
whitespace is only inserted or changed at places, where it's not significant. preserving whitespace may be controlled in a document tree by a tag attribute xml:space
allowed values for this attribute are default | preserve.
input is a complete document tree. result the semantically equivalent formatted tree.

simple filter for removing whitespace.
no check on sigificant whitespace is done.
simple recursive filter for removing all whitespace.
removes all text nodes in a tree that consist only of whitespace.
filter for removing all not significant whitespace.
the tree traversed for removing whitespace between tags, that was inserted for indentation and readability. whitespace is only removed at places, where it's not significat preserving whitespace may be controlled in a document tree by a tag attribute xml:space
allowed values for this attribute are default | preserve
input is root node of the document to be cleaned up output the semantically equivalent simplified tree

|converts CDATA sections in whole document tree|
|converts CDATA section in normal text nodes|
|converts CDATA sections in whole document tree into normal text nodes|
|converts character references to normal text|
|recursively converts all character references to normal text|
convert the special XML chars ", <, >, & and ' in a document to char references, attribute values are converted with escapeXmlAttrValue
convert the special XML chars in a text or comment node into character references
see also escapeXmlDoc
convert the special XML chars in an attribute value into charachter references. Not only the XML specials but also \n, \r and \t are converted
convert a document tree into an output string representation with respect to the output encoding.
The children of the document root are stubstituted by a single text node for the text representation of the document.
Encoding of the document is performed with respect to the output-encoding attribute in the root node, or if not present, of the encoding attribute for the original input encoding. If the encoding is not specified or not supported, UTF-8 is taken.
convert a document into a text and add line numbers to the text representation.
convert a document into a text representation in tree form.
convert a document into a Haskell representation (with show).
