public class Section extends CompositeNode
Represents a single section in a document.
To learn more, visit the Working with Sections documentation article.
Remarks:
Section can have one Body and maximum one HeaderFooter of each HeaderFooterType. Body and HeaderFooter nodes can be in any order inside Section.
A minimal valid section needs to have Body with one Paragraph.
Each section has its own set of properties that specify page size, orientation, margins etc.
You can create a copy of a section using Node.deepClone(boolean). The copy can be inserted into the same or different document.
To add, insert or remove a whole section including section break and section properties use methods of the Document.getSections() object.
To copy and insert just content of the section excluding the section break and section properties use appendContent(com.aspose.words.Section) and prependContent(com.aspose.words.Section) methods.
Examples:
Shows how to construct an Aspose.Words document by hand.
Document doc = new Document();
// A blank document contains one section, one body and one paragraph.
// Call the "RemoveAllChildren" method to remove all those nodes,
// and end up with a document node with no children.
doc.removeAllChildren();
// This document now has no composite child nodes that we can add content to.
// If we wish to edit it, we will need to repopulate its node collection.
// First, create a new section, and then append it as a child to the root document node.
Section section = new Section(doc);
doc.appendChild(section);
// Set some page setup properties for the section.
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);
// A section needs a body, which will contain and display all its contents
// on the page between the section's header and footer.
Body body = new Body(doc);
section.appendChild(body);
// Create a paragraph, set some formatting properties, and then append it as a child to the body.
Paragraph para = new Paragraph(doc);
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);
body.appendChild(para);
// Finally, add some content to do the document. Create a run,
// set its appearance and contents, and then append it as a child to the paragraph.
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);
Assert.assertEquals("Hello World!", doc.getText().trim());

Parameters:
| Parameter | Type | Description |
|---|---|---|
| doc | DocumentBase | The owner document. |
accept(DocumentVisitor visitor)
public boolean accept(DocumentVisitor visitor)
Accepts a visitor.
Remarks:
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.
Calls DocumentVisitor.visitSectionStart(com.aspose.words.Section), then calls Node.accept(com.aspose.words.DocumentVisitor) for all child nodes of the section and calls DocumentVisitor.visitSectionEnd(com.aspose.words.Section) at the end.
Parameters:
| Parameter | Type | Description |
|---|---|---|
| visitor | DocumentVisitor | The visitor that will visit the nodes. |
Returns: boolean - True if all nodes were visited; false if DocumentVisitor stopped the operation before visiting all nodes.
appendChild(Node newChild)
public Node appendChild(Node newChild)
Adds the specified node to the end of the list of child nodes for this node.
Remarks:
If the newChild is already in the tree, it is first removed.
If the node being inserted was created from another document, you should use M:Aspose.Words.DocumentBase.ImportNode(Aspose.Words.Node,System.Boolean,Aspose.Words.ImportFormatMode) to import the node to the current document. The imported node can then be inserted into the current document.
Examples:
Shows how to construct an Aspose.Words document by hand.
Document doc = new Document();
// A blank document contains one section, one body and one paragraph.
// Call the "RemoveAllChildren" method to remove all those nodes,
// and end up with a document node with no children.
doc.removeAllChildren();
// This document now has no composite child nodes that we can add content to.
// If we wish to edit it, we will need to repopulate its node collection.
// First, create a new section, and then append it as a child to the root document node.
Section section = new Section(doc);
doc.appendChild(section);
// Set some page setup properties for the section.
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);

// A section needs a body, which will contain and display all its contents
// on the page between the section's header and footer.
Body body = new Body(doc);
section.appendChild(body);
// Create a paragraph, set some formatting properties, and then append it as a child to the body.
Paragraph para = new Paragraph(doc);
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);
body.appendChild(para);
// Finally, add some content to do the document. Create a run,
// set its appearance and contents, and then append it as a child to the paragraph.
Run run = new Run(doc);

The nodes are automatically imported if the source section belongs to a different document.
No new section is created in the destination document.
Examples:
Shows how to append the contents of a section to another section.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Insert the contents of the first section to the beginning of the third section.
Section sectionToPrepend = doc.getSections().get(0);
section.prependContent(sectionToPrepend);
// Insert the contents of the second section to the end of the third section.
Section sectionToAppend = doc.getSections().get(1);
section.appendContent(sectionToAppend);
// The "PrependContent" and "AppendContent" methods did not create any new sections.
Assert.assertEquals(3, doc.getSections().getCount());
Assert.assertEquals("Section 1" + ControlChar.PARAGRAPH_BREAK +
"Section 3" + ControlChar.PARAGRAPH_BREAK +

Assert.assertEquals("", doc.getText().trim());
Assert.assertEquals(1, doc.getFirstSection().getBody().getParagraphs().getCount());
clearHeadersFooters()
public void clearHeadersFooters()
Clears the headers and footers of this section.
Remarks:
The text of all headers and footers is cleared, but HeaderFooter objects themselves are not removed.
This makes headers and footers of this section linked to headers and footers of the previous section.
Examples:
Shows how to clear the contents of all headers and footers in a section.
Document doc = new Document();
Assert.assertEquals(0, doc.getFirstSection().getHeadersFooters().getCount());
DocumentBuilder builder = new DocumentBuilder(doc);
builder.moveToHeaderFooter(HeaderFooterType.HEADER_PRIMARY);
builder.writeln("This is the primary header.");

Assert.assertEquals("Section 2\fSection 2", doc.getText().trim());
Returns: Section
deepClone(boolean isCloneChildren)
public Node deepClone(boolean isCloneChildren)
Creates a duplicate of the node.
Remarks:
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.
Examples:
Shows how to clone a composite node.
Document doc = new Document();
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();
para.appendChild(new Run(doc, "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.
Node cloneWithChildren = para.deepClone(true);

// Create a primary header with a shape.
builder.moveToHeaderFooter(HeaderFooterType.HEADER_PRIMARY);
builder.insertShape(ShapeType.RECTANGLE, 100.0, 100.0);
// Create a primary footer with an image.
builder.moveToHeaderFooter(HeaderFooterType.FOOTER_PRIMARY);
builder.insertImage(getImageDir() + "Logo Icon.ico");
Assert.assertEquals(1, doc.getFirstSection().getHeadersFooters().getByHeaderFooterType(HeaderFooterType.HEADER_PRIMARY).getChildNodes(NodeType.SHAPE, true).getCount());
Assert.assertEquals(1, doc.getFirstSection().getHeadersFooters().getByHeaderFooterType(HeaderFooterType.FOOTER_PRIMARY).getChildNodes(NodeType.SHAPE, true).getCount());
// Remove all shapes from the headers and footers in the first section.
doc.getFirstSection().deleteHeaderFooterShapes();
Assert.assertEquals(0, doc.getFirstSection().getHeadersFooters().getByHeaderFooterType(HeaderFooterType.HEADER_PRIMARY).getChildNodes(NodeType.SHAPE, true).getCount());

Returns null if the section does not have a Body node among its children.
Examples:
Clears main text from all sections from the document leaving the sections themselves.
Document doc = new Document();
// A blank document contains one section, one body and one paragraph.
// Call the "RemoveAllChildren" method to remove all those nodes,
// and end up with a document node with no children.
doc.removeAllChildren();
// This document now has no composite child nodes that we can add content to.
// If we wish to edit it, we will need to repopulate its node collection.
// First, create a new section, and then append it as a child to the root document node.
Section section = new Section(doc);
doc.appendChild(section);
// A section needs a body, which will contain and display all its contents
// on the page between the section's header and footer.
Body body = new Body(doc);
section.appendChild(body);
// This body has no children, so we cannot add runs to it yet.

|---|---|---|
| nodeType | int | |
| index | int | |
| isDeep | boolean |
Returns: Node
getChildNodes()
public NodeCollection getChildNodes()
Gets all immediate child nodes of this node.
Remarks:
Note, getChildNodes() is equivalent to calling M:Aspose.Words.CompositeNode.GetChildNodes(Aspose.Words.NodeType,System.Boolean) with arguments ( NodeType.ANY, false ) and creates and returns a new collection every time it is accessed.
If there are no child nodes, this property returns an empty collection.
Examples:
Shows how to traverse through a composite node’s collection of child nodes.
Document doc = new Document();
// Add two runs and one shape as child nodes to the first paragraph of this document.
Paragraph paragraph = (Paragraph) doc.getChild(NodeType.PARAGRAPH, 0, true);
paragraph.appendChild(new Run(doc, "Hello world! "));
Shape shape = new Shape(doc, ShapeType.RECTANGLE);
shape.setWidth(200.0);
shape.setHeight(200.0);
// Note that the 'CustomNodeId' is not saved to an output file and exists only during the node lifetime.
shape.setCustomNodeId(100);
shape.setWrapType(WrapType.INLINE);
paragraph.appendChild(shape);
paragraph.appendChild(new Run(doc, "Hello again!"));
// Iterate through the paragraph's collection of immediate children,
// and print any runs or shapes that we find within.
NodeCollection children = paragraph.getChildNodes();
Assert.assertEquals(3, paragraph.getChildNodes().getCount());
for (Node child : (Iterable) children)
switch (child.getNodeType()) {
case NodeType.RUN:

Assert.assertEquals("Initial text.", paragraph.getText().trim());
// Insert the second run into the paragraph in front of the initial run.
paragraph.insertBefore(run2, paragraphText);
Assert.assertEquals("Run 2. Initial text.", paragraph.getText().trim());
// Insert the third run after the initial run.
paragraph.insertAfter(run3, paragraphText);
Assert.assertEquals("Run 2. Initial text. Run 3.", paragraph.getText().trim());
// Insert the first run to the start of the paragraph's child nodes collection.
