Struct EvaluationCtx

pub(crate) struct EvaluationCtx {
    pub(crate) starting_node: DomRoot<Node>,
    pub(crate) context_node: DomRoot<Node>,
    pub(crate) predicate_ctx: Option<PredicateCtx>,
    pub(crate) predicate_nodes: Option<Vec<DomRoot<Node>>>,
}

The context during evaluation of an XPath expression.

Fields

starting_node: DomRoot<Node>

Where we started at

context_node: DomRoot<Node>

The “current” node in the evaluation

predicate_ctx: Option<PredicateCtx>

Details needed for evaluating a predicate list

predicate_nodes: Option<Vec<DomRoot<Node>>>

The nodes we’re currently matching against

Implementations

impl EvaluationCtx

pub(crate) fn new(context_node: &Node) -> EvaluationCtx

Prepares the context used while evaluating the XPath expression

pub(crate) fn subcontext_for_node(&self, node: &Node) -> EvaluationCtx

Creates a new context using the provided node as the context node

pub(crate) fn update_predicate_nodes(&self, nodes: Vec<&Node>) -> EvaluationCtx

pub(crate) fn subcontext_iter_for_nodes(&self) -> EvalNodesetIter<'_>

pub(crate) fn resolve_namespace( &self, prefix: Option<&str>, ) -> Option<DOMString>

Resolve a namespace prefix using the context node’s document

Trait Implementations

impl Debug for EvaluationCtx

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
