Schema compile findings now carry ValidationError coding paths that resolve to source spans on a ranged tree, enabling IDE underlines for id, structure, include, and facet violations.
Document the weak-parent ownership trap at the public entry points: parseTree
and readTree now state that a tree (or ownerDocument) must be held while using
any node inside it, that TreeNode has no internal synchronization (confine to
one thread or actor), and that the immutable Sendable Node projection is the
way across concurrency boundaries; the TreeNode class doc carries the same
contract. QualifiedName's malformed-colon fallback (':local', 'prefix:', '::'
stay whole and unprefixed), already implemented, is now documented on init
and locked by a test.
Closes#114
Add the DOM/tree editing primitives from the audit that the editor use
case needs:
- Attribute helpers: attributeValue(_:), setAttribute(_:_:) (update in
place or append), removeAttribute(_:).
- shallowCopy() copies a node alone, complementing the deep copy().
- precedes(_:) compares two nodes in document order (ancestor before
descendant, earlier sibling before later; unrelated nodes compare false).
- normalize() coalesces adjacent text children, drops empty text, and
recurses into elements; CDATA is left intact.
First-class namespace/DOCTYPE/entity-reference nodes (an invasive
TreeNodeKind change) and cross-document adoption/ownerDocument (no
document-identity model) are left for a follow-up.
Closes#90
Slice 4 of #94 (completes the epic). Quick-fixes are derived from the structured
schema completions, never by parsing a diagnostic message:
- TreeNode gains contentRange (the span between an element's start and end tags),
captured by the ranged reader, so an inserted attribute or child is placed
exactly.
- QuickFix and TextEdit model an editor edit (a replacement over a source range;
an insertion is a zero-width range).
- QuickFixEngine turns a Completions into fixes: a required-but-absent attribute
becomes an insertion before the start tag's >, and a still-expected required
child becomes an insertion before the end tag. Schema.Document.quickFixes(at:in:)
is the entry over a ranged tree.
Tests apply a fix and re-validate: adding the required id, or inserting the
required qty, yields XML the schema then accepts; a complete element offers none.
#94 (editor integration) is complete: ranged recovering read, unified lint,
schema completions, and quick-fixes.
Slice 1 of #94 (editor integration). The keystone: a located validation finding
can now be mapped back to a source range.
- TreeNode gains a sourceRange (start/end Mark); SourceRange is a half-open span.
- PureXML.readTree builds a mutable, parent-aware, best-effort tree whose every
node carries its span (an element from the < of its start tag to past its end
tag; leaves over the text they consumed). Never throws, recovers in place,
returns located diagnostics.
- TreeNode.node(at:) navigates a validation coding path to its node using the
same canonical convention the validators build paths with (a sibling index
only when a name repeats), and sourceRange(at:) returns the span. So
Document.validate's ValidationError.codingPath resolves to characters in the
document.
Tests prove the spans, the navigation, the end-to-end bridge (an XSD finding to
a source range), and that ranged reading of invalid input never crashes.
Add PureXML.Model.TreeNode, a reference-type document tree that knows its
parent and siblings. Navigation goes up and sideways (parent, nextSibling,
previousSibling, ancestors, root, elementChildren, stringValue) and editing
is in place (append, insert before/after, removeFromParent, replace, copy).
Children are held strongly and the parent weakly; attaching a node detaches
it from any prior parent and a node can never become its own ancestor.
parseTree builds one from XML; TreeNode.node converts back for serialization.
Closes#31
Add namespace resolution following the XML Namespaces rules, reimplemented in
Swift from libxml2's SAX2 model; no upstream code copied.
- QualifiedName gains an optional resolved namespaceURI (nil for names built
directly or in no namespace), with a resolved(namespaceURI:) helper.
- NamespaceContext maintains a scope stack of xmlns bindings as elements open
and close, resolving element and attribute names against it.
- A default namespace applies to unprefixed element names but never to
attributes; the xml prefix is built in; xmlns declarations are preserved as
attributes so documents round-trip; an unbound prefix raises
ParseError.undefinedNamespacePrefix. End-tag matching stays lexical.
- Namespace-free documents are unchanged (URIs remain nil).
- 7 namespace tests; 39 total.
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
