HTML Parser and Tree Builder
Parse HTML, good and bad.
HTML5 tokeniser with SAX-style events.
Flexible tree builder API for custom DOM implementations.
Readily provided HTML5 parser classes convert HTML documents into DOM trees:
Simple DOM tree: Fast and efficient.
LibXml2 tree: Fully compatible with LibXml2 functions, including XPATH and LibXslt transformation.
XDOM tree: Feasability study limited by XDOM restrictions.
Fast, efficient, and low memory usage.

DIZipWriter is a Delphi component to create PKZip-compatible ZIP archives. Archive output is based on TStream and writes directlyfiles (TFileStream), memory (TMemoryStream), or database BLOBs (TBlobStream).

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.

DIUnicode's Pascal implementation features more than 70 encodings, like UTF-7, UTF-8, UTF-16, the ISO-8859 family, various Windows and Macintosh codepages, KOI8 character sets, Chinese GB18030, and more. Adding a new character coding is as simple as writing a single conversion procedure. It supports 144 character sets and encodings when linked against DIConverters.

DITidy is build on the libtidy library but requires no DLLs not other external files. All code is compiled into the application's executable.

DISQLite3 implements a self-contained, embeddable, zero-configuration SQL database engine for Delphi (Embarcadero / CodeGear / Borland).

DIRegEx is a library of components and procedures that implement regular expression pattern matching using the same syntax and semantics as Perl for Delphi (Embarcadero / CodeGear / Borland).

DIHtmlParser is a component suite to parse, analyze, extract information from, and generate HTML, XHTML, and XML documents for Delphi (Embarcadero, CodeGear, Borland).

DIContainers is designed with easy customization in mind. Unlike other libraries, it strictly separates a containers' data and structure:

Data describes an individual item in the container, for example an Integer number. The data layer is mostly responsible to manage the item's memory, but also for copying, comparing, and streaming of items. Data items in DIContainers are made up of memory efficient Pascal records. Special item handlers take care to initialize and finalize items automatically as required.

ZipForge is a fast and powerful VCL Zip component, written in Delphi. It lets you easily create ZIP archives, extract files from zip files to hard drive or memory, add files to a zip archive from disk or memory, replace, move and delete files in zip archives. Also it creates and reads self-extracting (SFX) zip archives, AES encrypted and multi-volume zip files.
