import_node method
import_node(src_node, is_import_children)
Imports a node from another document to the current document.
def import_node(self, src_node: aspose.words.Node, is_import_children: bool):
...
| Parameter | Type | Description |
|---|---|---|
| src_node | Node | The node being imported. |
| is_import_children | bool | True to import all child nodes recursively; otherwise, False. |
Remarks
This method uses the ImportFormatMode.USE_DESTINATION_STYLES option to resolve formatting.
Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.
Before a node from another document can be inserted into this document, it must be imported. During import, document-specific properties such as references to styles and lists are translated from the original to the importing document. After the node was imported, it can be inserted into the appropriate place in the document using CompositeNode.insert_before() or CompositeNode.insert_after().
If the source node already belongs to the destination document, then simply a deep clone of the source node is created.
Returns
The cloned node that belongs to the current document.
import_node(src_node, is_import_children, import_format_mode)
Imports a node from another document to the current document with an option to control formatting.
def import_node(self, src_node: aspose.words.Node, is_import_children: bool, import_format_mode: aspose.words.ImportFormatMode):
...
| Parameter | Type | Description |
|---|---|---|
| src_node | Node | The node to imported. |
| is_import_children | bool | True to import all child nodes recursively; otherwise, False. |
| import_format_mode | ImportFormatMode | Specifies how to merge style formatting that clashes. |
Remarks
This overload is useful to control how styles and list formatting are imported.
Importing a node creates a copy of the source node belonging to the importing document. The returned node has no parent. The source node is not altered or removed from the original document.

If the source node already belongs to the destination document, then simply a deep clone of the source node is created.
Returns
The cloned, imported node. The node belongs to the destination document, but has no parent.
Examples
Shows how to import a node from one document to another.
src_doc = aw.Document()
dst_doc = aw.Document()
src_doc.first_section.body.first_paragraph.append_child(aw.Run(src_doc, 'Source document first paragraph text.'))

# Every node has a parent document, which is the document that contains the node.
# Inserting a node into a document that the node does not belong to will throw an exception.
self.assertNotEqual(dst_doc, src_doc.first_section.document)

dst_doc.append_child(src_doc.first_section)
# Use the "import_node" method to create a copy of a node, which will have the document
# that called the ImportNode method set as its new owner document.
imported_section = dst_doc.import_node(src_doc.first_section, True).as_section()
self.assertEqual(dst_doc, imported_section.document)
# We can now insert the node into the document.
dst_doc.append_child(imported_section)
self.assertEqual('Destination document first paragraph text.\r\nSource document first paragraph text.\r\n', dst_doc.to_string(aw.SaveFormat.TEXT))
Shows how to import node from source document to destination document with specific options.
# Create two documents and add a character style to each document.

# If we use ImportFormatMode.KeepDifferentStyles, the source style is preserved,
# and the naming clash resolves by adding a suffix.
