## Properties

actualEncoding

  Deprecated. Actual encoding of the document, is a readonly equivalent to encoding.

config

  Deprecated. Configuration used when DOMDocument::normalizeDocument() is invoked.

doctype

  The Document Type Declaration associated with this document.

documentElement

  This is a convenience attribute that allows direct access to the child node that is the document element of the document.

documentURI

  The location of the document or `NULL` if undefined.

encoding

  Encoding of the document, as specified by the XML declaration. This attribute is not present in the final DOM Level 3 specification, but is the only way of manipulating XML document encoding in this implementation.

formatOutput

  Nicely formats output with indentation and extra space.

implementation

  The DOMImplementation object that handles this document.

preserveWhiteSpace

  Do not remove redundant white space. Default to `TRUE`.

recover

  Proprietary. Enables recovery mode, i.e. trying to parse non-well formed documents. This attribute is not part of the DOM specification and is specific to libxml.

resolveExternals

  Set it to `TRUE` to load external entities from a doctype declaration. This is useful for including character entities in your XML document.

standalone

  Deprecated. Whether or not the document is standalone, as specified by the XML declaration, corresponds to xmlStandalone.

strictErrorChecking

  Throws DOMException on errors. Default to `TRUE`.

substituteEntities

  Proprietary. Whether or not to substitute entities. This attribute is not part of the DOM specification and is specific to libxml.

validateOnParse

  Loads and validates against the DTD. Default to `FALSE`.

version

  Deprecated. Version of XML, corresponds to xmlVersion.

xmlEncoding

  An attribute specifying, as part of the XML declaration, the encoding of this document. This is `NULL` when unspecified or when it is not known, such as when the Document was created in memory.

xmlStandalone

  An attribute specifying, as part of the XML declaration, whether this document is standalone. This is `FALSE` when unspecified.

xmlVersion

  An attribute specifying, as part of the XML declaration, the version number of this document. If there is no declaration and if this document supports the "XML" feature, the value is "1.0".

## Notes

> Note:

> The DOM extension uses UTF-8 encoding. Use utf8_encode() and utf8_decode() to work with texts in ISO-8859-1 encoding or Iconv for other encodings.
