virtual ASPOSECPP_SHARED_API SharedPtr<XPathNodeIterator> System::Xml::XPath::XPathNodeIterator::Clone ( )

pure virtual

When overridden in a derived class, returns a clone of this XPathNodeIterator object.

Returns: A new XPathNodeIterator object clone of this XPathNodeIterator object.

◆ get_Count()

virtual ASPOSECPP_SHARED_API int32_t System::Xml::XPath::XPathNodeIterator::get_Count ( )

pure virtual

When overridden in a derived class, gets the XPathNavigator object for this XPathNodeIterator, positioned on the current context node.

Returns: An XPathNavigator object positioned on the context node from which the node set was selected. The XPathNodeIterator::MoveNext method must be called to move the XPathNodeIterator to the first node in the selected set.

◆ get_CurrentPosition()

virtual ASPOSECPP_SHARED_API int32_t System::Xml::XPath::XPathNodeIterator::get_CurrentPosition ( )

pure virtual

When overridden in a derived class, gets the index of the current position in the selected set of nodes.

Returns: The index of the current position.

overridevirtual

Returns an IEnumerator object to iterate through the selected node set.

Returns: An IEnumerator object to iterate through the selected node set.

Implements System::Collections::Generic::IEnumerable< SharedPtr< System::Xml::XPath::XPathNavigator > >.

◆ MoveNext()

virtual ASPOSECPP_SHARED_API bool System::Xml::XPath::XPathNodeIterator::MoveNext ( )

pure virtual

When overridden in a derived class, moves the XPathNavigator object returned by the XPathNodeIterator::get_Current method to the next node in the selected node set.

Returns: true if the XPathNavigator object moved to the next node; false if there are no more selected nodes.
