xml 5.3.1

A lightweight library for parsing, traversing, querying, transforming and building XML documents.

Changelog

5.3.0

• Dart 2.15 requirement.
• Upgrade to PetitParser 4.3.

5.2.0

• A series of read-only accessors that simplify navigating the XML DOM with XmlElements:
  • Add XmlNode.childElements.
  • Add XmlNode.siblings and XmlNode.siblingElements.
  • Add XmlNode.previousElementSibling and XmlNode.nextElementSibling.
  • Add XmlNode.ancestorElements, XmlNode.precedingElements, XmlNode.descendantElements, and XmlNode.followingElements.

5.1.1

• Fix printing of Exceptions.
• Fix parsing of DOCTYPE tags.

5.1.0

• Upgrade to PetitParser 4.1.0.

5.0.0

• Dart 2.12 requirement and null-safety.
• Add the possibility to XmlBuilder to add raw strings.
• Improve error reporting (particularly for fragment parsing).
• Default entity mapping is now a global setting.
• Improve tutorials and documentation.

4.5.0

• Fixed a bug in the XML name parsing where certain unicode planes were not correctly recognized.
• Removed const constructor from XmlEvent to be able to add a lazy initialized parentEvent field.
• Add XmlWithParentEvents that provides validation of event nesting and efficient access to the parent events. Use stream.withParentEvents() to annotate the stream accordingly.
• Add namespace resolution to events through event.namespaceUri. Note that the data is only available when the parent information is present (see above).
• Fix namespace resolutions for events in selected sub-tree nodes, even if the namespace declaration is not part of the visible DOM.
• Add stream.forEachEvent(onText: ...) for easier callback based stream processing.

4.4.0

• Add a XmlSubtreeSelector that allows efficient filtering of events in specific sub-trees. Use stream.selectSubtreeEvents(...) to filter the stream accordingly.
• Add more options to XML pretty printer, namely the possibility to sort and indent attributes.
• Add typed extension methods for all stream converters, for simpler and more fluent API.
• Improvements to documentation and examples.

4.3.0

• Improve error reporting of XmlBuilder and add possibility to build XmlDocumentFragments.
• Improvements to documentation and examples.

4.2.0

• Deprecate standalone XmlDocument parse(String input) method, and introduce factory methods in the respective nodes XmlDocument.parse(String input) and XmlDocumentFragment.parse(String input).
• Introduce getters and setters for XmlNode.innerText (in most cases an alias to XmlNode.text), XmlNode.innerXml and XmlNode.outerXml.
• Improved support for XmlDocumentFragment across the library.
• Remove the XmlDocument.text override, which returned null.
• Add XmlNode.replace(XmlNode other) to make it easier to replace nodes in an existing tree.
• Add XmlNode.getElement(String name) as a shortcut to find the first child element with a given name.
• Add XmlNode.firstElementChild and XmlNode.lastElementChild to easy access the first/last child element.
• Add support to selectively disable whitespace normalization while pretty-printing, for example document.toXmlString(pretty: true, preserveWhitespace: (node) => node is XmlElement && node.name.local == 'pre') would keep everything within <pre> tags as-is.

4.1.0

• Improve the pretty printing and the customization of the pretty printing:
  • XmlWriter and XmlPrettyWriter are now initialized with optional arguments.
  • Pretty printing now also supports to customize the newline support.
  • Example is updated to also syntax highlight / colorize the output.
• Add full namespace support to attribute accessors setAttribute and removeAttribute.
• Improved the documentation, particularly started a section on xml_events package.

4.0.0

• Cleanup the node hierarchy. Specifically removed XmlOwned and XmlParent that added a lot of complexity and confusion. Instead, introduced dedicated mixins for nodes with attributes (XmlHasAttributes), children (XmlHasChildren), names (XmlHasName) or parents (XmlHasParent).
• Introduce XmlDeclaration nodes, events and builder to make accessing XML version and encoding simpler.

3.7.0

• Update to PetitParser 3.0.0.
• Dart 2.7 compatibility and requirement.

3.6.0

• Entity decoding and encoding is now configurable with an XmlEntityMapping. All operations that read or write XML can now (optionally) be configured with an entity mapper.
• The default entity mapping used only maps XML entities, as opposed to all HTML entities as in previous versions. To get the old behavior use XmlDefaultEntityMapping.html5.
• Made XmlParserError a FormatException to follow typical Dart exception style.
• Add an example demonstrating the interaction with HTTP APIs.

3.5.0

• Dart 2.3 compatibility and requirement.
• Turn various abstract classes into proper mixins.
• Numerous documentation improvements and code optimizations.
• Add an event parser example.

3.4.0

• Dart 2.2 compatibility and requirement.
• Take advantage of PetitParser fast-parse mode:
  • 15-30% faster DOM parsing, and
  • 15-50% faster event parsing.
• Improve error messages and reporting.

3.3.0

• New events based parsing in xml_events:
  • Lazy event parsing from an XML string into an Iterable of XmlEvent.
  • Async converters between streams of XML, XmlEvent and XmlNode.
• Clean up package structure by moving internal packages into the src/ subtree.
• Remove the experimental SAX parser, the event parser allows more flexible streaming XML consumption.

3.2.4

• Remove unnecessary whitespace when printing self-closing tags.
• Remember if an element is self-closing for stable printing.
