XML is the Extensible Markup Language, a format for the exchange of
structured data.
XML, which is a simplified subset of SGML, was designed as a universal
structured document format, but it is general enough to represent
arbitrary structured data in a text file. The format of a
XML file is
given separately in a
DocumentTypeDefinition (DTD) or another
SchemaLanguageForXML. The
XML syntax is quite verbose and not (necessarily) meant to be read by humans.
XML
imposes a hierarchical tree structure on the data.
GraX?,
GXL, and RDF
all use
XML for data exchange. (Quoted from
ExchangeFormatBibliography)
There are a number of systems for processing and transforming
XML documents
There are also other
ExchangeFormats, some of which are based on
XML.
For parsing, three approaches are frequently used:
Concerning the Hyper Text Markup Language
HTML we are
all so familiar with,
there is a redefinition of
HTML-4 into XHTML1,
which makes
HTML really conform to the
XML standard.
