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.

⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: pubspec.lock

Command failed: flutter pub upgrade xml
Because flutter_local_notifications 21.0.0 depends on flutter_local_notifications_windows ^3.0.0 which depends on xml ^6.5.0, flutter_local_notifications 21.0.0 requires xml ^6.5.0.
So, because wispar depends on both flutter_local_notifications 21.0.0 and xml ^7.0.0, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Consider downgrading your constraint on xml: flutter pub add xml:^6.6.1
