Closure XML Parser

An XML parser written in Common Lisp.

Closure XML was written by Gilbert Baumann (unk6 at rz.uni-karlsruhe.de) as part of the Closure web browser.
Contributions to the parser by

• Henrik Motakef (hmot at henrik-motakef.de)
  (SAX layer; namespace support)
• David Lichteblau for knowledgeTools (conversion into an independent package; DOM bug fixing; validation) and headcraft (most september/october 2004 changes) and privately (changes since then).

CXML implements a namespace-aware, validating XML 1.0 parser as well as the DOM Level 2 Core interfaces. Two parser interfaces are offered, one SAX-like, the other similar to StAX.

CXML is licensed under Lisp-LGPL.

Relax NG validation is available as a separate project: cxml-rng.

• xml:base support (SAX and Klacks only, not yet used in DOM). See documentation here and here.
• New class broadcast-handler as a generalization of the older sax-proxy.
• New class tapping-source, a klacks source that relays events from an upstream klacks source unchanged, while also emitting them as SAX events to a user-specified handler at the same time.
• Changed attributes to carry an lname even when occurring without a namespace.
• Klacks improvements: Incompatibly changed klacks:find-element and find-event to consider the current event as a result. Added klacks-error, klacks:expect, klacks:skip, klacks:expecting-element. Fixed serialize-event to generate start-prefix-mapping and end-prefix-mapping events. New function map-current-namespace-declarations.
