Property Getters/Setters Detail

• getDocument

  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));

• getEditableRange

  public EditableRange getEditableRange()
  

  Gets the facade object that encapsulates this editable range start and end.

  Example:

  Shows how to work with an editable range.

  DocumentBuilder builder = new DocumentBuilder(doc);
  builder.writeln("Hello world! Since we have set the document's protection level to read-only," +
          " we cannot edit this paragraph without the password.");
  
  // Editable ranges allow us to leave parts of protected documents open for editing.
  EditableRangeStart editableRangeStart = builder.startEditableRange();
  builder.writeln("This paragraph is inside an editable range, and can be edited.");
  EditableRangeEnd editableRangeEnd = builder.endEditableRange();
  
  // A well-formed editable range has a start node, and end node.
  // These nodes have matching IDs and encompass editable nodes.
  EditableRange editableRange = editableRangeStart.getEditableRange();
  
  Assert.assertEquals(editableRangeStart.getId(), editableRange.getId());
  Assert.assertEquals(editableRangeEnd.getId(), editableRange.getId());
  
  // Different parts of the editable range link to each other.
  Assert.assertEquals(editableRangeStart.getId(), editableRange.getEditableRangeStart().getId());
  Assert.assertEquals(editableRangeStart.getId(), editableRangeEnd.getEditableRangeStart().getId());
  Assert.assertEquals(editableRange.getId(), editableRangeStart.getEditableRange().getId());
  Assert.assertEquals(editableRangeEnd.getId(), editableRange.getEditableRangeEnd().getId());
  
  // We can access the node types of each part like this. The editable range itself is not a node,
  // but an entity which consists of a start, an end, and their enclosed contents.
  Assert.assertEquals(NodeType.EDITABLE_RANGE_START, editableRangeStart.getNodeType());
  Assert.assertEquals(NodeType.EDITABLE_RANGE_END, editableRangeEnd.getNodeType());
  
  builder.writeln("This paragraph is outside the editable range, and cannot be edited.");
  
  doc.save(getArtifactsDir() + "EditableRange.CreateAndRemove.docx");
  
  // Remove an editable range. All the nodes that were inside the range will remain intact.
  editableRange.remove();

• getId/setId

  public int getId() / public void setId(int value)
  

  Specifies the identifier of the editable range.

  Example:

  Shows how to work with an editable range.

  System.out.println("Paragraph has a parent node: " + (para.getParentNode() != null));

• getPreviousSibling

  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());

• getRange

  public Range getRange()

  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

• getText

  public java.lang.String getText()

  Gets the text of this node and of all its children.

  The returned string includes all control and special characters as described in ControlChar.

  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");

  Example:

  Shows how to use control characters.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Insert paragraphs with text with DocumentBuilder.
  builder.writeln("Hello world!");
  builder.writeln("Hello again!");
  
  // Converting the document to text form reveals that control characters
  // represent some of the document's structural elements, such as page breaks.
  Assert.assertEquals(MessageFormat.format("Hello world!{0}", ControlChar.CR) +
                  MessageFormat.format("Hello again!{0}", ControlChar.CR) +
                  ControlChar.PAGE_BREAK, doc.getText());
  
  // When converting a document to string form,
  // we can omit some of the control characters with the Trim method.

  Returns:

  The content of the node in the specified format.

  Parameters:

  saveFormat - A SaveFormat value.

  Example:

  Shows how to extract the label of each paragraph in a list as a value or a String.

  Document doc = new Document(getMyDir() + "Rendering.docx");
  doc.updateListLabels();
  int listParaCount = 1;
  
  for (Paragraph paragraph : (Iterable<Paragraph>) doc.getChildNodes(NodeType.PARAGRAPH, true)) {
      // Find if we have the paragraph list. In our document our list uses plain arabic numbers,
      // which start at three and ends at six
      if (paragraph.getListFormat().isListItem()) {
          System.out.println(MessageFormat.format("List item paragraph #{0}", listParaCount));
  
          // This is the text we get when actually getting when we output this node to text format
          // The list labels are not included in this text output. Trim any paragraph formatting characters
          String paragraphText = paragraph.toString(SaveFormat.TEXT).trim();
          System.out.println("Exported Text: " + paragraphText);
  
          ListLabel label = paragraph.getListLabel();
          // This gets the position of the paragraph in current level of the list. If we have a list with multiple level then this
          // will tell us what position it is on that particular level
          System.out.println("\tNumerical Id: " + label.getLabelValue());
  
          // Combine them together to include the list label with the text in the output

          listParaCount++;
      }
  }

  Example:

  Exports the content of a node to String in HTML format.

  Document doc = new Document(getMyDir() + "Document.docx");
  
  // Extract the last paragraph in the document to convert to HTML
  Node node = doc.getLastSection().getBody().getLastParagraph();
  
  // When ToString is called using the html SaveFormat overload then the node is converted directly to html

  Example:

  Shows the difference between calling the GetText and ToString methods on a node.

  Document doc = new Document();
  
  DocumentBuilder builder = new DocumentBuilder(doc);
  builder.insertField("MERGEFIELD Field");
  
  // GetText will retrieve the visible text as well as field codes and special characters.
  Assert.assertEquals("\u0013MERGEFIELD Field\u0014«Field»\u0015\f", doc.getText());
  
  // ToString will give us the document's appearance if saved to a passed save format.
  Assert.assertEquals("«Field»\r\n", doc.toString(SaveFormat.TEXT));
