Examples
Shows how to print the node structure of every editable range in a document.
void EditableRangeToText()
{
auto doc = MakeObject<Document>(MyDir + u"DocumentVisitor-compatible features.docx");
auto visitor = MakeObject<ExDocumentVisitor::EditableRangeStructurePrinter>();
// When we get a composite node to accept a document visitor, the visitor visits the accepting node,
// 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;
}
