procedure ReadXMLFragment(AParentNode: TDOMNode; var f: TStream); overload;
procedure ReadXMLFragment(AParentNode: TDOMNode; var f: TStream; const ABaseURI: WideString); overload;

procedure ReadDTDFile(out ADoc: TXMLDocument; const AFilename: WideString); overload;
procedure ReadDTDFile(out ADoc: TXMLDocument; var f: Text); overload;
procedure ReadDTDFile(out ADoc: TXMLDocument; var f: TStream); overload;
procedure ReadDTDFile(out ADoc: TXMLDocument; var f: TStream; const ABaseURI: WideString); overload;

Encodings

The parser can read files encoded in UTF-8, UTF-16 (both endianness), and ISO-8859-1.

White space handling

Regarding whitespace handling: By default, whitespace directly after the beginning of a tag is discarded, and sections of the XML file which contain only whitespace and no other text content are discarded as well. However, whitespace-preserving mode can be enabled by setting TDOMParser.Options.PreserveWhitespace property to True.

DTD support

It supports DTD validation. Regarding entity references: The pre-defined entities "lt", "gt", "amp", "apos" and "quot", and internal entities declared in DTD, are replaced by their defined values during reading. Ability to resolve external entities is currently limited to the file system.
