7.22 SXML

SXML is a native representation of XML in terms of standard Scheme data types: lists, symbols, and strings. For example, the simple XML fragment:

<parrot type="African Grey"><name>Alfie</name></parrot>

may be represented with the following SXML:

(parrot (@ (type "African Grey")) (name "Alfie"))

SXML is very general, and is capable of representing all of XML. Formally, this means that SXML is a conforming implementation of the http://www.w3.org/TR/xml-infoset/ standard.

Guile includes several facilities for working with XML and SXML: parsers, serializers, and transformers.

• SXML Overview: XML, as it was meant to be

• Reading and Writing XML: Convenient XML parsing and serializing

• SSAX: Custom functional-style XML parsers

• Transforming SXML: Munging SXML with pre-post-order

• SXML Tree Fold: Fold-based SXML transformations

• SXPath: XPath for SXML

• sxml ssax input-parse: The SSAX tokenizer, optimized for Guile

• sxml apply-templates: A more XSLT-like approach to SXML transformations
