Delphi-XmlLite
Header translation for Microsoft XmlLite
- XmlLite is a native C++ implementation of .NET XmlReader+Writer for stream-based, forward-only XML parsing and creation.
- XmlLite.dll is required. It is included with all new versions of Windows, and service packs for old versions.
- XmlReader's pull-based interface is cleaner to use than SAX's event-based interface.

Note: This is a minimal translation, some parts were not implemented and most are untested.
Sample code taken from production. We use this to generate very large (>1GB) Xml files from an array of temporary files.
procedure AppendFile(const FileName: string; _IXMLWriter: IXMLWriter);
var
_IXMLReader: IXMLReader;
NodeType: Integer;
LocalName: PWideChar;
LocalNameLen: LongWord;
begin
_IXMLReader := CreateXmlFileReader(FileName);
while not _IXMLReader.IsEOF do
begin
_IXMLReader.GetLocalName(LocalName, LocalNameLen);
if (LocalName = 'SecondLevelNodeName') then
_IXMLWriter.WriteNode(_IXMLReader, True)
else
_IXMLReader.Read(NodeType);
end;
end;procedure CombineXmlFiles(const FileName: string; TempXmlFileArray: StringArray);
var
_IXMLWriter : IXMLWriter;
iCounter: Integer;
begin
_IXMLWriter := CreateXmlFileWriter(FileName);_IXMLWriter.SetProperty(XmlWriterProperty_Indent, LongInt(True));_IXMLWriter.WriteStartDocument(XmlStandalone_Omit);
_IXMLWriter.WriteStartElement(nil, PWideChar('RootNodeName'), nil);for iCounter := 0 to High(TempXmlFileArray) do
AppendFile(TempXmlFileArray[iCounter], _IXMLWriter);_IXMLWriter.WriteEndElement;
_IXMLWriter.WriteEndDocument;
_IXMLWriter.Flush;end;
