| IMPORT_C TXmlEngNode | operator[](TInt) |
This class implements the node set container, which is one of the result type in XPath.
| IMPORT_C TBool | Contains | ( | TXmlEngNode | aNode | ) | const |
Checks whether a node is in the node set.
| Parameters | |
|---|---|
| aNode | The node to check |
| IMPORT_C void | Free | ( | ) |
Frees any allocated resources.
As a node set only refers to existing nodes in the DOM tree, no nodes are freed. However, namespace declarations are copied into the node set and these copies are indeed freed.
| IMPORT_C void | InitializeL | ( | ) |
Initializes the node set to an empty state.

This method is used when preparing node sets that will be used with RXmlEngXPathExpression::EvaluateWithDependenciesL(TXmlEngNode,RXmlEngNodeSet&) and TXmlEngXPathEvaluator::EvaluateWithDependenciesL(aExpression,aContextNode,aResolver,aDependents).
