XPathConfiguration class

Static configuration for XPath evaluation.

Constructors

XPathConfiguration({Map<String, Object?>? variables, Map<XmlName, XPathFunctionItem>? functions, String? namespaceUri, Map<String, String>? namespaceUris, Map<String, XmlNode>? documents, Map<String, List<XmlNode>>? collections, Map<String, String>? environment, String? baseUri, XPathUnparsedTextLoader? unparsedTextLoader, XPathTraceCallback? onTraceCallback})

Creates a static context extending the standard configuration.

factory

XPathConfiguration.raw({Map<String, XPathSequence> variables = const {}, Map<XmlName, XPathFunctionItem> functions = const {}, String? namespaceUri, Map<String, String> namespaceUris = const {}, Map<String, XmlNode> documents = const {}, Map<String, List<XmlNode>> collections = const {}, Map<String, String> environment = const {}, String? baseUri, XPathUnparsedTextLoader? unparsedTextLoader, XPathTraceCallback? onTraceCallback})

Creates a static configuration from scratch without any of the standard functions or namespaces.

const

XPathConfiguration.standard()

Creates a standard static configuration.

Methods

context([Object item = XPathSequence.empty]) → XPathContext

Creates an evaluation context from this configuration, optionally with a provided context item.

Creates a modified copy of the static context.

getFunction(XmlName name, [int? arity]) → XPathFunctionItem

Looks up an XPath function with the given name and optional arity.

getFunctionByString(String name, [int? arity]) → XPathFunctionItem

Looks up an XPath function by name (string) and optional arity.
