DIXml is an embedded XML, XSLT, and EXSLT processing library for Delphi (Embarcadero / CodeGear / Borland). It is build on the libxml2, libxslt and libexslt libraries. However, DIXml requires no DLLs or any other external files whatsoever. All required code is compiled completely into the application's executable. DIXml is the most feature-complete XML and XSLT solution for Delphi.

Features
XML and HTML reading and writing, pull and push parser modes.
XML and HTML document tree creation, traversal, load, and save.
SAX and extended reader interfaces.
DTD and schema validation.
Encoding support for UTF-8, UTF-16, ISO-8859-family, ASCII (all native).
XPATH processing.
NameSpace support.
XSLT transformation and processing.
File, memory, and customized input / output.
Low memory usage, outstanding performance.
