Libxml is the XML C library developed for the Gnome project. XML itself
is a metalanguage to design markup languages, i.e. text language where
semantic and structure are added to the content using extra "markup"
information enclosed between angle brackets. HTML is the most well-known
markup language. Though the library is written in C a
variety of language bindings make it available in other environments.
Libxml2 implements a number of existing standards related to markup
languages:
In most cases libxml tries to implement the specifications in a relatively
strictly compliant way. As of release 2.4.16, libxml2 passes all 1800+ tests from the OASIS XML Tests
Suite.
To some extent libxml2 provides support for the following additional
specifications but doesn't claim to implement them completely:
- Document Object Model (DOM) http://www.w3.org/TR/DOM-Level-2-Core/
it doesn't implement the API itself, gdome2 does this on top of
libxml2
-
RFC 959 :
libxml implements a basic FTP client code
-
RFC 1945 :
HTTP/1.0, again a basic HTTP client code
- SAX: a minimal SAX implementation compatible with early expat
versions
- DocBook SGML v4: libxml2 includes a hackish parser to transition to
XML
XML Schemas is being worked on but it would be far too early to make any
conformance statement about it at the moment.
Libxml2 is known to be very portable, the library should build and work
without serious troubles on a variety of systems (Linux, Unix, Windows,
CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, ...)
