Release Notes

renggli/dart-xml (xml)

v7.0.1

Compare Source

• Better namespace support across all parts of the library:
  • Namespaces of XmlDocument.parse and XmlDocumentFragment.parse are now resolved at parse-time and constant when manipulating the DOM (this aligns with other XML libraries and removes surprising behavior when moving nodes around).
  • Deprecate all namespace arguments and replace them with the more intention revealing namespaceUri and namespacePrefix.
  • Lower-level parser and event APIs can now enable and disable the validation and resolution of namespaces with validateNamespaces and withNamespaces. This is a BREAKING CHANGE to existing code using these lower-level APIs, as namespaces are no longer available by default.
  • Introduced XmlNamespaceException for error reporting of invalid namespaces.
  • XmlName is now immutable and the complexity with different states is gone.
  • Added XmlNamespace node type and XmlHasNamespaces mixin to support reading in-scope namespaces on nodes.
• Correctly move nodes from their previous parent when inserting them into a new location, rather than throwing an XmlParentException. This aligns with standard DOM behavior and improves usability and performance. XmlDocumentFragment nodes are automatically expanded and their children are moved as well.
• Improved performance and usability of XmlBuilder:
  • Significantly improve the performance of XmlBuilder as all namespace lookups are now in constant time.
  • Deprecated namespace(String uri, String? prefix) and namespaces(Map<String, String?> uriToPrefix) accessors that have an unusually awkward API. Replaced with namespaceUri(String? prefix, String? uri) and namespaceUris(Map<String, String> prefixToUri) with a clear prefix-uri order.
  • Deprecated String? namespace arguments when definition elements and attributes. Replaced with more flexible String namespacePrefix and String namespaceUri.
• Comprehensive XPath 3.1 support:
  • Complete execution model supporting sequences of items (nodes, atomic values, functions, maps, and arrays).
  • New expressions and operators: String concatenation (||), range (to), quantified (some/every), loops (for), simple map (!), lookup (?), and node comparison (is, <<, >>).
  • Support for Higher-Order Functions: Inline, named, and arrow functions, inclusive of partial function application and dynamic binding with fn:function-lookup.
  • Native support for XPath Data Model (XDM) maps and arrays, including associated JSON and sequence functions.
  • Added support for EQName parsing (Q{uri}name).
  • Add missing XPath name tests (namespace prefix, namespace URI, local name, and wildcards) and node tests (attribute(), document-node() and element()).
  • Significantly improve XPath evaluation performance for large documents (thanks to laishere).
  • Fix issues with XPath axis parsing, reverse axis access, and predicate expressions (thanks to laishere).
• Update to PetitParser 7.0.2.

v7.0.0

Compare Source

v6.6.1

Compare Source

• Dart and Flutter 3.9 compatibility.
• Minor optimization to eliminate unused namespaces.

v6.6.0

Compare Source

• Dart 3.8 and PetitParser 7.0 requirement.
• Correct decoding of names with surrogate characters.

v6.5.0

Compare Source

• Add support for most XPath 1.0 functions, including set-operations and ensuring document order for node-sets.
• Add support for XPath expression evaluation, user-defined variables, and user-defined functions.
• Add XmlNode.xpathGenerate to create a readable XPath for all nodes.
• Add support for node comparison: XmlNode.isEqualNode and XmlNode.compareNodePosition.

v6.4.2

Compare Source

v6.4.1

Compare Source

v6.4.0

Compare Source

• Dart 3.0 and PetitParser 6.0 requirement.
• Add RSS feed reader example.

v6.3.0

Compare Source

• Upgrade to Dart 2.19 and PetitParser 5.4.
• Add XmlElement.tag constructor that greatly simplifies the creation of elements, i.e. XmlElement(XmlName('br'), [], [], true) becomes XmlElement.tag('br', isSelfClosing: true).
• Deprecate the ambiguous XmlNode.text: Replace with XmlNode.value to access the textual contents of the node, or XmlNode.innerText to access the textual contents of its descendants.
• Fix XmlNode.siblings and various related methods to also work correctly on XmlAttribute nodes, make the method return a mutable list.
• Improve XmlNode.replace(XmlNode) and add XmlNode.remove() for easy removal of a node.
• Improve error position propagation when building the XML DOM.
• Make the parser more forgiving when reading attributes.
• Experimental support of a subset of XPath.
• Add new-line normalization support.

v6.2.2

Compare Source

v6.2.1

Compare Source

v6.2.0

Compare Source

• Upgrade to PetitParser 5.1 brings a 10% speed improvement (typed sequences).
• Add the ability to tap into a stream of XmlEvent with tapEachEvent (similar to forEachEvent).
• Remove XmlName equality operator == and hashCode. This is inconsistent with the other DOM nodes, and the provided implementation might not have the desired behavior.
• Improved error reporting when accessing innerText or innerXml on DOM nodes that cannot have children.

v6.1.0

Compare Source

• Dart 2.17 requirement.
• Validate the presence and order of root nodes when parsing; this got lost in 6.0.0 and can now also optionally be enabled for streaming and iterable parsers.
• Add support for basic document type parsing. The contents of the XmlDoctype can now be accessed through name, externalId and internalSubset.
