- cdataAsText emits a CDATA section's content as escaped text instead of
a <![CDATA[ ... ]]> section.
- asciiOnly escapes every non-ASCII character as a numeric character
reference, so the output is pure ASCII (libxml2's character-reference
encoding).
Both apply to the Serializer and the incremental Writer through the
shared Escaping rules.
Closes#91
Broaden the serializer and writer options from the audit:
- attributeQuote selects single or double quotes; the active quote is
escaped in values (apostrophe as ' in single-quote mode).
- lineEnding controls the inserted newline (set to CRLF for \r\n output).
- xml:space=preserve suppresses pretty-print indentation for an element
and its subtree; xml:space=default re-enables it.
- Writer gains writeStartElementNS(prefix:localName:namespaceURI:) and
writeNamespace(prefix:uri:), so callers no longer hand-format prefixes
and xmlns attributes.
CDATA-vs-escape and entity re-escaping strategies are left as a
follow-up; the current escaping is the safe default.
Closes#91
Add includeXMLDeclaration, xmlVersion, encodingName, and standalone to
Emitting.Options, with a single shared xmlDeclaration computation consumed
by both the tree serializer and the incremental writer. Writer gains
writeStartDocument(). Defaults stay off so fragment output is unchanged.
Closes#34
Root Swift package mirroring PureYAML's structure, rules, and verification
gates. Includes the XML node model (Node, Element, Attribute, QualifiedName),
a working emitter (Serializer) with escaping and pretty/compact options, and
structural validation. The parser surface is stable; parse() raises
notImplemented until the scanner lands, pinned by a test.
- dependency-free, namespaced under PureXML
- portability and style gates carried over (style, namespacing, forbidden
patterns, swiftformat, swiftlint, linux, wasm, windows CI)
- 11 tests passing
