ixp_runtime library
Utilities for writing an XML parser.
These add extension methods to XML Events and a StreamQueue of XML Events, enabling code such as: ` const NoteName = 'Note';
Future
Preparing the stream:
generateEventsStream prepares the StreamQueue for use:
StreamQueue(source.toXmlEvents().withParentEvents().normalizeEvents().flatten());
You will need to call these yourself if your input isn't a
Stream<String>.
Classes
- Convert
- Conversion methods from String to the Dart primitive types.
- EndOfQueue
- Indicates that the parser ran out of XML Events while looking for the end of a tag.
- MissingAttribute
- Indicates that an expected attribute wasn't found.
- MissingEndTag
- Indicates that an end tag wasn't found for the current start tag.
- MissingStartTag
- Indicates that an expected (and required) start tag wasn't found.
- MissingText
- Indicates that expected text wasn't found.
- ParsingError
- UnexpectedChild
Extensions
- Ancestors on XmlParented
- AttributeExtension on XmlStartElementEvent
-
Consume
on StreamQueue<
XmlEvent> -
Find
on StreamQueue<
XmlEvent> - Logging on XmlStartElementEvent
Functions
-
autoConverter(
Type T) → Converter - Returns a converter from String to the specified primitive type.
-
generateEventStream(
Stream< String> source) → StreamQueue<XmlEvent> - Converts a stream of Strings, such as from a file, to to a StreamQueue of XML Events ready for parsing.
-
inside(
XmlStartElementEvent tag) → Matcher< XmlEvent> - True if the current event is the between the specified start tag and its end tag, inclusive.
-
named(
String desiredName) → Matcher< XmlEvent> - Matches tags with the provided qualified name.
-
not(
Matcher< XmlEvent> match) → Matcher<XmlEvent> -
startTag(
[Matcher< XmlEvent> ? match]) → Matcher<XmlStartElementEvent> -
Wraps another matcher so it only sees
XmlStartElementEvent. -
textElement(
[Matcher< XmlEvent> ? match]) → Matcher<XmlTextEvent> -
Wraps another matcher so it only sees
XmlTextEvent.
