Detailed Description

Represents a collection of nodes matching an XPath query executed using the Aspose::Words::CompositeNode::SelectNodes(System::String) method.

NodeList is returned by Aspose::Words::CompositeNode::SelectNodes(System::String) and contains a collection of nodes matching the XPath query.

NodeList supports indexed access and iteration.

Note
Treat the NodeList collection as a "snapshot" collection. NodeList starts as a "live" collection because the nodes are not actually retrieved when the XPath query is run. The nodes are only retrieved upon access and at this time the node and all nodes that precede it are cached forming a "snapshot" collection.

Constructor & Destructor Documentation

◆ NodeList()

Aspose::Words::NodeList::NodeList ( const System::SharedPtr< Aspose::Words::NodeCollection > &  nodes)

Member Function Documentation

◆ get_Count()

int32_t Aspose::Words::NodeList::get_Count ( ) const

Gets the number of nodes in the list.

◆ GetEnumerator()

System::SharedPtr<System::Collections::Generic::IEnumerator<System::SharedPtr<Aspose::Words::Node> > > Aspose::Words::NodeList::GetEnumerator ( )
overridevirtual

Provides a simple "foreach" style iteration over the collection of nodes.

Returns
An IEnumerator.

Implements System::Collections::Generic::IEnumerable< System::SharedPtr< Aspose::Words::Node > >.

◆ idx_get()

System::SharedPtr<Aspose::Words::Node> Aspose::Words::NodeList::idx_get ( int32_t  index) const

Retrieves a node at the given index.

The index is zero-based.

Negative indexes are allowed and indicate access from the back of the collection. For example -1 means the last item, -2 means the second before last and so on.

If index is greater than or equal to the number of items in the list, this returns a null reference.

If index is negative and its absolute value is greater than the number of items in the list, this returns a null reference.

Parameters
indexAn index into the list of nodes.
