    public static void main(String[] args) {
        // Your code here
    }
}

Loading and Parsing Documents

Loading a Word Document

Let’s start by loading a Word document:

// Load the document
Document doc = new Document("sample.docx");

Parsing the Document Structure

Now that we have our document loaded, let’s parse its structure:

// Create a DocumentVisitor
DocumentVisitor visitor = new DocumentVisitor();

// Traverse the document
doc.accept(visitor);

// Extracted content is now available in the visitor
String extractedText = visitor.getText();

Extracting Content by Pages

What are Document Pages?

In Aspose.Words, a document can be divided into pages. Each page represents a portion of the document’s content. But how do we access these pages programmatically?

Extracting Text from a Specific Page

// Specify the page number (zero-based index)
int pageNumber = 0;

// Extract text from the specified page
PageInfo pageInfo = doc.getPageInfo(pageNumber);
String pageText = doc.extractText(pageInfo);

Looping Through All Pages

To extract content from all pages, you can use a simple loop:

// Get the total number of pages in the document
int pageCount = doc.getPageCount();

for (int i = 0; i < pageCount; i++) {
    PageInfo pageInfo = doc.getPageInfo(i);
    String pageText = doc.extractText(pageInfo);
    // Process the extracted content as needed
}

Manipulating Extracted Content

Formatting and Styling Text

You can apply formatting and styling to the extracted text, just like you would with any other text in Java. For example, to make text bold:

// Create a DocumentBuilder
DocumentBuilder builder = new DocumentBuilder(doc);

// Insert formatted text
builder.getFont().setBold(true);
builder.write("This text is bold.");

Saving Extracted Content to a New Document

Once you’ve extracted and manipulated the content, you can save it to a new document:

// Save the extracted content to a new document
doc.save("extracted_content.docx");
