Aspose::Words::DocumentVisitor::VisitSmartTagEnd method

DocumentVisitor::VisitSmartTagEnd method

Called when enumeration of a smart tag has ended.

virtual Aspose::Words::VisitorAction Aspose::Words::DocumentVisitor::VisitSmartTagEnd(System::SharedPtr<Aspose::Words::Markup::SmartTag> smartTag)

Parameter	Type	Description
smartTag	System::SharedPtr<Aspose::Words::Markup::SmartTag>	The object that is being visited.

ReturnValue

A VisitorAction value that specifies how to continue the enumeration.

Examples

Shows how to print the node structure of every smart tag in a document.

    // and then traverses all the node's children in a depth-first manner.
    // The visitor can read and modify each visited node.
    doc->Accept(visitor);

    std::cout << visitor->GetText() << std::endl;
