Struct script::xpath::context::EvaluationCtx
source · pub struct EvaluationCtx {
pub starting_node: Root<Dom<Node>>,
pub context_node: Root<Dom<Node>>,
pub predicate_ctx: Option<PredicateCtx>,
pub predicate_nodes: Option<Vec<Root<Dom<Node>>>>,
}Expand description
The context during evaluation of an XPath expression.
Fields§
§starting_node: Root<Dom<Node>>Where we started at
context_node: Root<Dom<Node>>The “current” node in the evaluation
predicate_ctx: Option<PredicateCtx>Details needed for evaluating a predicate list
predicate_nodes: Option<Vec<Root<Dom<Node>>>>The nodes we’re currently matching against
