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.

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.

Returns: int
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.

// 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);

Assert.assertEquals("Hello World!", doc.getText().trim());
doc.save(getArtifactsDir() + "Section.CreateManually.docx");
Parameters:
| Parameter | Type | Description |
|---|---|---|
| newChild | Node | The node to add. |
Returns: Node - The node added.
appendContent(Section sourceSection)
public void appendContent(Section sourceSection)
Inserts a copy of content of the source section at the end of this section.
Remarks:
Only content of getBody() of the source section is copied, page setup, headers and footers are not copied.
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);
builder.write("Section 1");
builder.insertBreak(BreakType.SECTION_BREAK_NEW_PAGE);
builder.write("Section 2");
builder.insertBreak(BreakType.SECTION_BREAK_NEW_PAGE);
builder.write("Section 3");
Section section = doc.getSections().get(2);
Assert.assertEquals("Section 3" + ControlChar.SECTION_BREAK, section.getText());
// 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 +
"Section 2" + ControlChar.SECTION_BREAK, section.getText());
Parameters:
| Parameter | Type | Description |
|---|---|---|
| sourceSection | Section | The section to copy content from. |
clearContent()
public void clearContent()
Clears the section.
Remarks:
The text of getBody() is cleared, only one empty paragraph is left that represents the section break.
The text of all headers and footers is cleared, but HeaderFooter objects themselves are not removed.
Examples:
Shows how to clear the contents of a section.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.write("Hello world!");
Assert.assertEquals("Hello world!", doc.getText().trim());
Assert.assertEquals(1, doc.getFirstSection().getBody().getParagraphs().getCount());
// Running the "ClearContent" method will remove all the section contents
// but leave a blank paragraph to add content again.
doc.getFirstSection().clearContent();
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);

selectNodes(String xpath)
public NodeList selectNodes(String xpath)
Selects a list of nodes matching the XPath expression.
Remarks:
Only expressions with element names are supported at the moment. Expressions that use attribute names are not supported.
Examples:
Shows how to use an XPath expression to test whether a node is inside a field.
Document doc = new Document(getMyDir() + "Mail merge destination - Northwind employees.docx");
// The NodeList that results from this XPath expression will contain all nodes we find inside a field.
// However, FieldStart and FieldEnd nodes can be on the list if there are nested fields in the path.
// Currently does not find rare fields in which the FieldCode or FieldResult spans across multiple paragraphs.
NodeList resultList =
doc.selectNodes("//FieldStart/following-sibling::node()[following-sibling::FieldEnd]");
Run[] runs = Arrays.stream(resultList.toArray()).filter(n -> n.getNodeType() == NodeType.RUN).toArray(Run[]::new);
Run run = runs[0];
// Check if the specified run is one of the nodes that are inside the field.
System.out.println(MessageFormat.format("Contents of the first Run node that''s part of a field: {0}", run.getText().trim()));
Shows how to select certain nodes by using an XPath expression.
Document doc = new Document(getMyDir() + "Tables.docx");
// This expression will extract all paragraph nodes,
// which are descendants of any table node in the document.
NodeList nodeList = doc.selectNodes("//Table//Paragraph");
// Iterate through the list with an enumerator and print the contents of every paragraph in each cell of the table.
int index = 0;
Iterator e = nodeList.iterator();
while (e.hasNext()) {
Node currentNode = e.next();
System.out.println(MessageFormat.format("Table paragraph index {0}, contents: \"{1}\"", index++, currentNode.getText().trim()));
}
// This expression will select any paragraphs that are direct children of any Body node in the document.
nodeList = doc.selectNodes("//Body/Paragraph");
// We can treat the list as an array.
Assert.assertEquals(nodeList.toArray().length, 4);
// Use SelectSingleNode to select the first result of the same expression as above.
Node node = doc.selectSingleNode("//Body/Paragraph");
Assert.assertEquals(Paragraph.class, node.getClass());
Parameters:
| Parameter | Type | Description |

Returns: NodeList - A list of nodes matching the XPath query.
selectSingleNode(String xpath)
public Node selectSingleNode(String xpath)
Selects the first Node that matches the XPath expression.
Remarks:
Only expressions with element names are supported at the moment. Expressions that use attribute names are not supported.
Examples:
Shows how to select certain nodes by using an XPath expression.
Document doc = new Document(getMyDir() + "Tables.docx");
// This expression will extract all paragraph nodes,
// which are descendants of any table node in the document.
NodeList nodeList = doc.selectNodes("//Table//Paragraph");
// Iterate through the list with an enumerator and print the contents of every paragraph in each cell of the table.

setCustomNodeId(int value)
public void setCustomNodeId(int value)
Specifies custom node identifier.
Remarks:
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.
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(NodeType.ANY, false);
Assert.assertEquals(3, paragraph.getChildNodes(NodeType.ANY, false).getCount());
for (Node child : (Iterable) children)
switch (child.getNodeType()) {
case NodeType.RUN:
System.out.println("Run contents:");
System.out.println(MessageFormat.format("\t\"{0}\"", child.getText().trim()));
break;
case NodeType.SHAPE:
Shape childShape = (Shape)child;
