Working with Text

Extract Text from OneNote Document

One of the tasks that developers need to perform is extracting text from a OneNote document. Aspose.Note for Java allows developers to extract text from a OneNote document in various ways.

Aspose.Note for Java offers the Document class that represents a OneNote file. The Document class exposes the GetText method that can be called to extract text from a OneNote document.

This article shows how to:

• Extract all text from OneNote document.
• Extract text from a specified page of OneNote document.

Extracting All Text from OneNote Document

This example works as follows:

1. Create an object of the Document class.
2. Call the stream-based code to extract text.
3. Display text on the output screen.

The following example shows how to extract all text from a OneNote document.

// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(ExtractingAllText.class) + "text\\";

// Load the document into Aspose.Note.
Document oneFile = new Document(dataDir + "Sample1.one");

// Retrieve text
List<RichText> textNodes = (List<RichText>) oneFile.getChildNodes(RichText.class);
		StringBuilder text = new StringBuilder();
		for (RichText richText : textNodes) {
			text = text.append(richText.getText().toString());
		}

// Print text on the output screen
System.out.println(text);

Extracting Text from a Specified Page of a OneNote Document

This example works as follows:

1. Create an object of the Document class.
2. Filter out a list of page nodes.
3. Retrieve the page node by index.
4. Call the stream-based code to extract text.
5. Display the text on the output screen.

The following example shows how to extract text from a specified page in a OneNote document.

// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(ExtractingTextFromAPage.class) + "text\\";

// Load the document into Aspose.Note.
Document oneFile = new Document(dataDir + "Sample1.one");

// Get list of page nodes
List<Node> nodes = oneFile.getChildNodes(Node.class);

if (nodes.size() > 0 && nodes.get(0).getNodeType() == NodeType.Page)
{
    Page page = (Page)nodes.get(0);
    // Retrieve text
    List<RichText> textNodes = (List<RichText>) page.getChildNodes(RichText.class);
			StringBuilder text = new StringBuilder();
			for (RichText richText : textNodes) {
				text = text.append(richText.getText().toString());
			}
			
			// Print text on the output screen
    System.out.println(text);
}

Replace Text in Pages of a OneNote Document and Save as PDF

Aspose.Note for Java supports finding and then replacing text within a OneNote document.

Aspose.Note for Java offers the Document class that represents a OneNote file.

This article shows how to:

• Replace text on all pages.
• Replace text on a particular page.

Replace Text on All Pages

The following example shows how to replace text on all pages.

String dataDir = Utils.getSharedDataDir(ReplaceTextonAllPages.class) + "text/";

Map<String, String> replacements = new HashMap<String, String>();
replacements.put("2. Get organized", "New Text Here");

// Load the document into Aspose.Note.
LoadOptions options = new LoadOptions();
Document oneFile = new Document(dataDir + "Sample1.one", options);

// Get all RichText nodes
List<RichText> textNodes = (List<RichText>) oneFile.getChildNodes(RichText.class);// <RichText.class>();

// Traverse all nodes and compare text against the key text
for (RichText richText : textNodes) {
	for (String key : replacements.keySet()) {
		if (richText != null && richText.getText().contains(key)) {
			// Replace text of a shape
			richText.setText(richText.getText().replace(key, replacements.get(key)));
		}
	}
}

// Save to any supported file format
oneFile.save(dataDir + "ReplaceTextonAllPages_out.pdf", SaveFormat.Pdf);

Replace Text on a Particular Page

The following example shows how to replace text on a particular page.

String dataDir = Utils.getSharedDataDir(ReplaceTextonParticularPage.class) + "text/";

Map<String, String> replacements = new HashMap<String, String>();
replacements.put("2. Get organized", "New Text Here");

// Load the document into Aspose.Note.
Document oneFile = new Document(dataDir + "Sample1.one", new LoadOptions());

List<Page> pageNodes = (List<Page>) oneFile.getChildNodes(Page.class);

// Get all RichText nodes
List<RichText> textNodes = (List<RichText>) pageNodes.get(0).getChildNodes(RichText.class);

for (RichText richText : textNodes) {
	for (String key : replacements.keySet()) {
		if (richText != null && richText.getText().contains(key)) {
			// Replace text of a shape
			richText.setText(richText.getText().replace(key, replacements.get(key)));
		}
	}
}

// Save to any supported file format
oneFile.save(dataDir + "ReplaceTextonParticularPage_out.pdf", SaveFormat.Pdf);

Retrieve Bullet or Number List Properties

Aspose.Note for Java provides comprehensive support for Microsoft OneNote lists. Developers can access a number of list properties, such as font name, numbering format, and many others.

Retrieving Properties

Aspose.Note for .NET offers the OutlineElement class that represents an outline inside a OneNote document. The OutlineElement class exposes the NumberList property that can be called to extract bullet or numbered list properties. The following example shows how to extract bullet or numbered list properties from a OneNote document.

Output Screen

String dataDir = Utils.getSharedDataDir(GetListProperties.class) + "text/";

// Load the document into Aspose.Note
Document oneFile = new Document(dataDir + "Sample1.one");

// Retrieve a collection nodes of the outline element
List<OutlineElement> nodes = oneFile.getChildNodes(OutlineElement.class);

// Iterate through each node
for (OutlineElement node : nodes) {
	if (node.getNumberList() != null) {
		NumberList list = node.getNumberList();
		// Retrieve font name
		System.out.println("Font Name: " + list.getFont());
		// Retrieve font length
		System.out.println("Font Length: " + list.getFont());
		// Retrieve font size
		System.out.println("Font Size: " + list.getFontSize());
		// Retrieve font color
		System.out.println("Font Color: " + list.getFontColor());
		// Retrieve format
		System.out.println("Font format: " + list.getFormat());
		// Check bold
		System.out.println("Is bold: " + list.isBold());
		// Check italic
		System.out.println("Is italic: " + list.isItalic());

		System.out.println();
	}
}

Apply Bullets on the Text

Arranging texts in bullet form is a very common approach. Aspose.Note for Java API allows developers to arrange text items in bullets.

Aspose.Note for Java offers the [Document]( https://reference.aspose.com/note/java/com.Aspose.Note.Document Class) class that represents a OneNote file. Writing text to a OneNote document page involves creating an OutlineElement, which offers NumberList property to define the bullet.

Please see a brief description to add and apply bullets on the text in OneNote document using the Aspose.Note APIs:

1. Create an instance of the Document class that represents a OneNote document.
2. Initialize three objects of Page class and set their levels.
3. Initialize the objects of Outline, OutlineElement and RichText classes. Setting the NumberList property of the OutlineElement class adds bullets.
4. The ParagraphStyle class defines the text formatting.
5. Generate the OneNote document by calling the Save method of the Document object.

The following example shows how to apply a bullet on the OneNote document.

String dataDir = Utils.getSharedDataDir(CreateBulletedList.class) + "text/";

// create an object of the Document class
Document doc = new Document();

// initialize Page class object
Page page = new Page(doc);

// initialize Outline class object
Outline outline = new Outline(doc);

// initialize TextStyle class object and set formatting properties
ParagraphStyle defaultStyle = new ParagraphStyle();
defaultStyle.setFontColor(Color.black);
defaultStyle.setFontName("Arial");
defaultStyle.setFontSize(10);

// initialize OutlineElement class objects and apply bullets
OutlineElement outlineElem1 = new OutlineElement(doc);
outlineElem1.setNumberList(new NumberList("*", "Arial", 10));

// initialize RichText class object and apply text style
RichText text1 = new RichText(doc);
text1.setText("First");
text1.setParagraphStyle(defaultStyle);
outlineElem1.appendChildLast(text1);

OutlineElement outlineElem2 = new OutlineElement(doc);
outlineElem2.setNumberList(new NumberList("*", "Arial", 10));

RichText text2 = new RichText(doc);
text2.setText("Second");
text2.setParagraphStyle(defaultStyle);
outlineElem2.appendChildLast(text2);

OutlineElement outlineElem3 = new OutlineElement(doc);
outlineElem3.setNumberList(new NumberList("*", "Arial", 10));
RichText text3 = new RichText(doc);
text3.setText("Third");
text3.setParagraphStyle(defaultStyle);
outlineElem3.appendChildLast(text3);

// add outline elements
outline.appendChildLast(outlineElem1);
outline.appendChildLast(outlineElem2);
outline.appendChildLast(outlineElem3);

// add Outline node
page.appendChildLast(outline);

// add Page node
doc.appendChildLast(page);

// save the document
doc.save(dataDir + "CreateBulletedList_out.pdf");

Apply Numbering on the Text

Arranging texts in numbering form is a very common approach. Aspose.Note for Java API allows developers to arrange text items in numbering.

Aspose.Note for Java offers the Document class that represents a OneNote file. Writing text to a OneNote document page involves creating an OutlineElement, which offers NumberList property to define the bullet.

Please see a brief description to add and apply bullets on the text in OneNote document using the Aspose.Note APIs:

1. Create an instance of the Document class that represents a OneNote document.
2. Initialize three objects of Page class and set their levels.
3. Initialize the objects of Outline, OutlineElement and RichText classes. Setting the NumberList property of the OutlineElement class adds bullets.
4. The ParagraphStyle class defines the text formatting.
5. Generate the OneNote document by calling the Save method of the Document object.

The following example shows how to apply a bullet on the OneNote document.

String dataDir = Utils.getSharedDataDir(CreateNumberedList.class) + "text/";

// create an object of the Document class
Document doc = new Document();

// initialize Page class object
Page page = new Page(doc);

// initialize Outline class object
Outline outline = new Outline(doc);

// initialize TextStyle class object and set formatting properties
ParagraphStyle defaultStyle = new ParagraphStyle();
defaultStyle.setFontColor(Color.black);
defaultStyle.setFontName("Arial");
defaultStyle.setFontSize(10);

// initialize OutlineElement class objects and apply numbering
// numbers in the same outline are automatically incremented.
OutlineElement outlineElem1 = new OutlineElement(doc);

outlineElem1.setNumberList(new NumberList("{0})", NumberFormat.DecimalNumbers, "Arial", 10));

RichText text1 = new RichText(doc);
text1.setText("First");
text1.setParagraphStyle(defaultStyle);
outlineElem1.appendChildLast(text1);

OutlineElement outlineElem2 = new OutlineElement(doc);
outlineElem2.setNumberList(new NumberList("{0})", NumberFormat.DecimalNumbers, "Arial", 10));
RichText text2 = new RichText(doc);
text2.setText("Second");
text2.setParagraphStyle(defaultStyle);
outlineElem2.appendChildLast(text2);

OutlineElement outlineElem3 = new OutlineElement(doc);
outlineElem3.setNumberList(new NumberList("{0})", NumberFormat.DecimalNumbers, "Arial", 10));
RichText text3 = new RichText(doc);
text3.setText("Third");
text3.setParagraphStyle(defaultStyle);
outlineElem3.appendChildLast(text3);

// add outline elements
outline.appendChildLast(outlineElem1);
outline.appendChildLast(outlineElem2);
outline.appendChildLast(outlineElem3);

// add Outline node
page.appendChildLast(outline);

// add Page node
doc.appendChildLast(page);

// save the document
doc.save(dataDir + "CreateNumberedList_out.pdf");

Insert Chinese Number List in the OneNote Document

Aspose.Note for Java API supports inserting the Chinese number list in the OneNote document.

Aspose.Note for Java offers the Document class that represents a OneNote file. Inserting the Chinese number list to a OneNote document page involves creating an OutlineElement, which offers NumberList property to define the bullet.

Creating Page Title in MS OneNote Style

Aspose.Note API allows creating a page tile in default MS OneNote Style. The DefaultMsOneNoteTitleParagraphStyle property of the ParagraphStyle class can be used to set the page title for this purpose.

Setting Page Title in Microsoft OneNote Style

String dataDir = Utils.getSharedDataDir(SettingPageTitleinMicrosoftOneNoteStyle.class) + "text/";

// initialize new Document
Document doc = new Document(dataDir + "Sample1.one");
// initialize new Page
Page page = new Page(doc);

// title text
RichText titleText = new RichText(doc);
titleText.setText("Title text.");
titleText.setParagraphStyle(ParagraphStyle.getDefault());

// title date
RichText titleDate = new RichText(doc);
titleDate.setText("2011,11,11");
titleDate.setParagraphStyle(ParagraphStyle.getDefault());

// title time
RichText titleTime = new RichText(doc);
titleTime.setText("12:34");
titleTime.setParagraphStyle(ParagraphStyle.getDefault());

Title title = new Title(doc);
title.setTitleText(titleText);
title.setTitleDate(titleDate);
title.setTitleTime(titleTime);
page.setTitle(title);

// append page node
doc.appendChildLast(page);
