Base class for all nodes of a Word document.

A document is represented as a tree of nodes, similar to DOM or XmlDocument.

For more info see the Composite design pattern.

The Node class:

Defines the child node interface.
Defines the interface for visiting nodes.
Provides default cloning capability.
Implements parent node and owner document mechanisms.
Implements access to sibling nodes.

Examples

Shows how to clone a composite node.

auto doc = MakeObject<Document>();
SharedPtr<Paragraph> para = doc->get_FirstSection()->get_Body()->get_FirstParagraph();
para->AppendChild(MakeObject<Run>(doc, u"Hello world!"));
 
// Below are two ways of cloning a composite node.

SharedPtr<Node> cloneWithChildren = para->Clone(true);
 
ASSERT_TRUE((System::DynamicCast<CompositeNode>(cloneWithChildren))->get_HasChildNodes());
ASSERT_EQ(u"Hello world!", cloneWithChildren->GetText().Trim());

SharedPtr<Node> cloneWithoutChildren = para->Clone(false);
 
ASSERT_FALSE((System::DynamicCast<CompositeNode>(cloneWithoutChildren))->get_HasChildNodes());
ASSERT_EQ(String::Empty, cloneWithoutChildren->GetText().Trim());

Shows how to traverse through a composite node's collection of child nodes.

◆ Accept()

virtual bool Aspose::Words::Node::Accept ( System::SharedPtr< Aspose::Words::DocumentVisitor > visitor )

pure virtual

Accepts a visitor.

Enumerates over this node and all of its children. Each node calls a corresponding method on DocumentVisitor.

For more info see the Visitor design pattern.

Parameters

visitor The visitor that will visit the nodes.

Returns: True if all nodes were visited; false if DocumentVisitor stopped the operation before visiting all nodes.

Examples

◆ Clone()

System::SharedPtr<Aspose::Words::Node> Aspose::Words::Node::Clone ( bool isCloneChildren )

Creates a duplicate of the node.

This method serves as a copy constructor for nodes. The cloned node has no parent, but belongs to the same document as the original node.

This method always performs a deep copy of the node. The isCloneChildren parameter specifies whether to perform copy all child nodes as well.

Parameters

isCloneChildren True to recursively clone the subtree under the specified node; false to clone only the node itself.

Returns: The cloned node.

Examples

Shows how to clone a composite node.

auto doc = MakeObject<Document>();
SharedPtr<Paragraph> para = doc->get_FirstSection()->get_Body()->get_FirstParagraph();
para->AppendChild(MakeObject<Run>(doc, u"Hello world!"));
 
// Below are two ways of cloning a composite node.
// 1 -  Create a clone of a node, and create a clone of each of its child nodes as well.
SharedPtr<Node> cloneWithChildren = para->Clone(true);
 
ASSERT_TRUE((System::DynamicCast<CompositeNode>(cloneWithChildren))->get_HasChildNodes());
ASSERT_EQ(u"Hello world!", cloneWithChildren->GetText().Trim());
 
// 2 -  Create a clone of a node just by itself without any children.
SharedPtr<Node> cloneWithoutChildren = para->Clone(false);
 
ASSERT_FALSE((System::DynamicCast<CompositeNode>(cloneWithoutChildren))->get_HasChildNodes());
ASSERT_EQ(String::Empty, cloneWithoutChildren->GetText().Trim());

◆ get_CustomNodeId()

int32_t Aspose::Words::Node::get_CustomNodeId ( ) const

Specifies custom node identifier.

Default is zero.

This identifier can be set and used arbitrarily. For example, as a key to get external data.

Important note, specified value is not saved to an output file and exists only during the node lifetime.

Examples

Shows how to traverse through a composite node's collection of child nodes.

auto doc = MakeObject<Document>();
 
// Add two runs and one shape as child nodes to the first paragraph of this document.
auto paragraph = System::DynamicCast<Paragraph>(doc->GetChild(NodeType::Paragraph, 0, true));
paragraph->AppendChild(MakeObject<Run>(doc, u"Hello world! "));
 
auto shape = MakeObject<Shape>(doc, ShapeType::Rectangle);
shape->set_Width(200);
shape->set_Height(200);
// Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
shape->set_CustomNodeId(100);
shape->set_WrapType(WrapType::Inline);
paragraph->AppendChild(shape);
 
paragraph->AppendChild(MakeObject<Run>(doc, u"Hello again!"));
 
// Iterate through the paragraph's collection of immediate children,
// and print any runs or shapes that we find within.
SharedPtr<NodeCollection> children = paragraph->get_ChildNodes();
 
ASSERT_EQ(3, paragraph->get_ChildNodes()->get_Count());
 
for (const auto& child : System::IterateOver(children))
{
    switch (child->get_NodeType())
    {

        auto childShape = System::DynamicCast<Shape>(child);
        std::cout << "Shape:" << std::endl;
        std::cout << String::Format(u"\t{0}, {1}x{2}", childShape->get_ShapeType(), childShape->get_Width(), childShape->get_Height()) << std::endl;
        ASSERT_EQ(100, shape->get_CustomNodeId());
        break;
    }
 
    default:
        break;
    }
}

◆ get_Document()

virtual System::SharedPtr<Aspose::Words::DocumentBase> Aspose::Words::Node::get_Document ( ) const

virtual

Gets the document to which this node belongs.

The node always belongs to a document even if it has just been created and not yet added to the tree, or if it has been removed from the tree.

Examples

Shows how to create a node and set its owning document.

auto doc = MakeObject<Document>();
auto para = MakeObject<Paragraph>(doc);
para->AppendChild(MakeObject<Run>(doc, u"Hello world!"));
 
// We have not yet appended this paragraph as a child to any composite node.
ASSERT_TRUE(para->get_ParentNode() == nullptr);
 
// If a node is an appropriate child node type of another composite node,
// we can attach it as a child only if both nodes have the same owner document.
// The owner document is the document we passed to the node's constructor.
// We have not attached this paragraph to the document, so the document does not contain its text.
ASPOSE_ASSERT_EQ(para->get_Document(), doc);
ASSERT_EQ(String::Empty, doc->GetText().Trim());
 
// Since the document owns this paragraph, we can apply one of its styles to the paragraph's contents.
para->get_ParagraphFormat()->set_Style(doc->get_Styles()->idx_get(u"Heading 1"));
 
// Add this node to the document, and then verify its contents.
doc->get_FirstSection()->get_Body()->AppendChild(para);
 
ASPOSE_ASSERT_EQ(doc->get_FirstSection()->get_Body(), para->get_ParentNode());
ASSERT_EQ(u"Hello world!", doc->GetText().Trim());

        {
