public DocumentBase getDocument()

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.

Example:

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

// Open a file from disk
Document doc = new Document();

// Creating a new node of any type requires a document passed into the constructor
Paragraph para = new Paragraph(doc);

// The new paragraph node does not yet have a parent
System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));

// But the paragraph node knows its document
System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));

// The fact that a node always belongs to a document allows us to access and modify 
// properties that reference the document-wide data such as styles or lists
para.getParagraphFormat().setStyleName("Heading 1");

// Now add the paragraph to the main text of the first section
doc.getFirstSection().getBody().appendChild(para);

// The paragraph node is now a child of the Body node
System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));

public int getFieldType()

Returns the type of the field. The value of the property is FieldType integer constant.

Example:

Demonstrates how to retrieve the field class from an existing FieldStart node in the document.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

FieldDate field = (FieldDate) builder.insertField(FieldType.FIELD_DATE, true);
field.getFormat().setDateTimeFormat("dddd, MMMM dd, yyyy");
field.update();

FieldChar fieldStart = field.getStart();
Assert.assertEquals(FieldType.FIELD_DATE, fieldStart.getFieldType());
Assert.assertEquals(false, fieldStart.isDirty());
Assert.assertEquals(false, fieldStart.isLocked());

// Retrieve the facade object which represents the field in the document
field = (FieldDate) fieldStart.getField();

Assert.assertEquals(false, field.isLocked());
Assert.assertEquals(" DATE  \\@ \"dddd, MMMM dd, yyyy\"", field.getFieldCode());

// Update the field to show the current date
field.update();

public Font getFont()

Provides access to the font formatting of this object.

Example:

Shows how to construct an Aspose Words document node by node.

Document doc = new Document();

// A newly created blank document still comes one section, one body and one paragraph
// Calling this method will remove all those nodes to completely empty the document
doc.removeAllChildren();

// This document now has no composite nodes that content can be added to
// If we wish to edit it, we will need to repopulate its node collection,
// which we will start to do with by creating a new Section node
Section section = new Section(doc);

// Append the section to the document
doc.appendChild(section);

// Lets set some properties for the section
section.getPageSetup().setSectionStart(SectionStart.NEW_PAGE);
section.getPageSetup().setPaperSize(PaperSize.LETTER);

// A section needs a body, which will contain all other nodes that can be edited
Body body = new Body(doc);
section.appendChild(body);

// The body needs to have at least one paragraph
// Note that the paragraph has not yet been added to the document, but we have to specify the parent document
// The parent document is needed so the paragraph can correctly work
// with styles and other document-wide information
Paragraph para = new Paragraph(doc);
body.appendChild(para);

// We can set some formatting for the paragraph
para.getParagraphFormat().setStyleName("Heading 1");
para.getParagraphFormat().setAlignment(ParagraphAlignment.CENTER);

// Now we can begin adding content to the document
Run run = new Run(doc);
run.setText("Hello World!");
run.getFont().setColor(Color.RED);
para.appendChild(run);

Assert.assertEquals("Hello World!" + ControlChar.SECTION_BREAK_CHAR, doc.getText());

doc.save(getArtifactsDir() + "Section.CreateFromScratch.docx");

public boolean hasSeparator()

Example:

Shows how to access the parent node.

Document doc = new Document();

// Get the document's first paragraph and append a child node to it in the form of a run with text
Paragraph para = doc.getFirstSection().getBody().getFirstParagraph();

// When inserting a new node, the document that the node will belong to must be provided as an argument
Run run = new Run(doc, "Hello world!");
para.appendChild(run);

// The node lineage can be traced back to the document itself
Assert.assertEquals(para, run.getParentNode());
Assert.assertEquals(doc.getFirstSection().getBody(), para.getParentNode());
Assert.assertEquals(doc.getFirstSection(), doc.getFirstSection().getBody().getParentNode());
Assert.assertEquals(doc, doc.getFirstSection().getParentNode());

Example:

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

// Open a file from disk
Document doc = new Document();

// Creating a new node of any type requires a document passed into the constructor
Paragraph para = new Paragraph(doc);

// The new paragraph node does not yet have a parent
System.out.println("Paragraph has no parent node: " + (para.getParentNode() == null));

// But the paragraph node knows its document
System.out.println("Both nodes' documents are the same: " + (para.getDocument() == doc));

// The fact that a node always belongs to a document allows us to access and modify 
// properties that reference the document-wide data such as styles or lists
para.getParagraphFormat().setStyleName("Heading 1");

// Now add the paragraph to the main text of the first section
doc.getFirstSection().getBody().appendChild(para);

// The paragraph node is now a child of the Body node
System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));

public Paragraph getParentParagraph()

Retrieves the parent Paragraph of this node.

Example:

Shows how to view revision-related properties of Inline nodes.

Document doc = new Document(getMyDir() + "Revision runs.docx");

// This document has 6 revisions
Assert.assertEquals(doc.getRevisions().getCount(), 6);

// The parent node of a revision is the run that the revision concerns, which is an Inline node
Run run = (Run) doc.getRevisions().get(0).getParentNode();

// Get the parent paragraph
Paragraph firstParagraph = run.getParentParagraph();
RunCollection runs = firstParagraph.getRuns();

Assert.assertEquals(runs.getCount(), 6);

// The text in the run at index #2 was typed after revisions were tracked, so it will count as an insert revision
// The font was changed, so it will also be a format revision
Assert.assertTrue(runs.get(2).isInsertRevision());
Assert.assertTrue(runs.get(2).isFormatRevision());

// If one node was moved from one place to another while changes were tracked,
// the node will be placed at the departure location as a "move to revision",
// and a "move from revision" node will be left behind at the origin, in case we want to reject changes
// Highlighting text and dragging it to another place with the mouse and cut-and-pasting (but not copy-pasting) both count as "move revisions"
// The node with the "IsMoveToRevision" flag is the arrival of the move operation, and the node with the "IsMoveFromRevision" flag is the departure point
Assert.assertTrue(runs.get(1).isMoveToRevision());
Assert.assertTrue(runs.get(4).isMoveFromRevision());

// If an Inline node gets deleted while changes are being tracked, it will leave behind a node with the IsDeleteRevision flag set to true until changes are accepted
Assert.assertTrue(runs.get(5).isDeleteRevision());

public Node getPreviousSibling()

Gets the node immediately preceding this node.

If there is no preceding node, a null is returned.

Example:

Shows how to use of methods of Node and CompositeNode to remove a section before the last section in the document.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// Create a second section by inserting a section break and add text to both sections
builder.writeln("Section 1 text.");
builder.insertBreak(BreakType.SECTION_BREAK_CONTINUOUS);
builder.writeln("Section 2 text.");

// Both sections are siblings of each other
Section lastSection = (Section) doc.getLastChild();
Section firstSection = (Section) lastSection.getPreviousSibling();

// Remove a section based on its sibling relationship with another section
if (lastSection.getPreviousSibling() != null)
    doc.removeChild(firstSection);

// The section we removed was the first one, leaving the document with only the second
Assert.assertEquals("Section 2 text.", doc.getText().trim());

public Range getRange()

Returns a Range object that represents the portion of a document that is contained in this node.

Example:

Shows how to delete all characters of a range.

// Insert two sections into a blank document
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.write("Section 1. ");
builder.insertBreak(BreakType.SECTION_BREAK_CONTINUOUS);
builder.write("Section 2.");

// Verify the whole text of the document
Assert.assertEquals("Section 1. \fSection 2.", doc.getText().trim());

// Delete the first section from the document
doc.getSections().get(0).getRange().delete();

// Check the first section was deleted by looking at the text of the whole document again
Assert.assertEquals("Section 2.", doc.getText().trim());

public boolean accept(DocumentVisitor visitor)
              throws java.lang.Exception
