Java: Read Content from a Word Document

Extracting content from Word documents plays a crucial role in both work and study. Extracting one page of content helps in quickly browsing and summarizing key points, while extracting content from one section aids in in-depth study of specific topics or sections. Extracting the entire document allows you to have a comprehensive understanding of the document content, facilitating deep analysis and comprehensive comprehension. This article will introduce how to use Spire.Doc for Java to read a page, a section, and the entire content of a Word document in a Java project.

Install Spire.Doc for Java

First, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Read a Page from a Word Document in Java

Using the FixedLayoutDocument class and FixedLayoutPage class makes it easy to extract content from a specified page. To facilitate viewing the extracted content, the following example code saves the extracted content to a new Word document. The detailed steps are as follows:

  • Create a Document object.
  • Load a Word document using the Document.loadFromFile() method.
  • Create a FixedLayoutDocument object.
  • Obtain a FixedLayoutPage object for a page in the document.
  • Use the FixedLayoutPage.getSection() method to get the section where the page is located.
  • Get the index position of the first paragraph on the page within the section.
  • Get the index position of the last paragraph on the page within the section.
  • Create another Document object.
  • Add a new section using Document.addSection().
  • Clone the properties of the original section to the new section using Section.cloneSectionPropertiesTo(newSection) method.
  • Copy the content of the page from the original document to the new document.
  • Save the resulting document using the Document.saveToFile() method.
  • Java
import com.spire.doc.*;
import com.spire.doc.pages.*;
import com.spire.doc.documents.*;

public class ReadOnePage {
    public static void main(String[] args) {
        // Create a new document object
        Document document = new Document();

        // Load document content from the specified file
        document.loadFromFile("Sample.docx");

        // Create a fixed layout document object
        FixedLayoutDocument layoutDoc = new FixedLayoutDocument(document);

        // Get the first page
        FixedLayoutPage page = layoutDoc.getPages().get(0);

        // Get the section where the page is located
        Section section = page.getSection();

        // Get the first paragraph of the page
        Paragraph paragraphStart = page.getColumns().get(0).getLines().getFirst().getParagraph();
        int startIndex = 0;
        if (paragraphStart != null) {
            // Get the index of the paragraph in the section
            startIndex = section.getBody().getChildObjects().indexOf(paragraphStart);
        }

        // Get the last paragraph of the page
        Paragraph paragraphEnd = page.getColumns().get(0).getLines().getLast().getParagraph();

        int endIndex = 0;
        if (paragraphEnd != null) {
            // Get the index of the paragraph in the section
            endIndex = section.getBody().getChildObjects().indexOf(paragraphEnd);
        }

        // Create a new document object
        Document newdoc = new Document();

        // Add a new section
        Section newSection = newdoc.addSection();

        // Clone the properties of the original section to the new section
        section.cloneSectionPropertiesTo(newSection);

        // Copy the content of the original document's page to the new document
        for (int i = startIndex; i <=endIndex; i++)
        {
            newSection.getBody().getChildObjects().add(section.getBody().getChildObjects().get(i).deepClone());
        }

        // Save the new document to the specified file
        newdoc.saveToFile("Content of One Page.docx", FileFormat.Docx);

        // Close and release the new document
        newdoc.close();
        newdoc.dispose();

        // Close and release the original document
        document.close();
        document.dispose();
    }
}

Java: Read Content from a Word Document

Read a Section from a Word Document in Java

Using Document.Sections[index], you can access specific Section objects that contain the header, footer, and body content of a document. The following example demonstrates a simple method to copy all content from one section to another document. The detailed steps are as follows:

  • Create a Document object.
  • Load a Word document using the Document.loadFromFile() method.
  • Use Document.getSections().get(1) to retrieve the second section of the document.
  • Create another new Document object.
  • Clone the default style of the original document to the new document using Document.cloneDefaultStyleTo(newdoc) method.
  • Use Document.getSections().add(section.deepClone()) to clone the content of the second section of the original document to the new document.
  • Save the resulting document using the Document.saveToFile() method.
  • Java
import com.spire.doc.*;

public class ReadOneSection {
    public static void main(String[] args) {
        // Create a new document object
        Document document = new Document();

        // Load a Word document from a file
        document.loadFromFile("Sample.docx");

        // Get the second section of the document
        Section section = document.getSections().get(1);

        // Create a new document object
        Document newdoc = new Document();

        // Clone the default style to the new document
        document.cloneDefaultStyleTo(newdoc);

        // Clone the second section to the new document
        newdoc.getSections().add(section.deepClone());

        // Save the new document to a file
        newdoc.saveToFile("Content of One Section.docx", FileFormat.Docx);

        // Close and release the new document object
        newdoc.close();
        newdoc.dispose();

        // Close and release the original document object
        document.close();
        document.dispose();
    }
}

Java: Read Content from a Word Document

Read the Entire Content from a Word Document in Java

This example demonstrates how to iterate through each section of the original document to read the entire content of the document and clone each section into a new document. This method can help you quickly replicate both the structure and content of the entire document, preserving the format and layout of the original document in the new document. Such operations are very useful for maintaining the integrity and consistency of the document structure. The detailed steps are as follows:

  • Create a Document object.
  • Load a Word document using the Document.loadFromFile() method.
  • Create another new Document object.
  • Clone the default style of the original document to the new document using the Document.cloneDefaultStyleTo(newdoc) method.
  • Iterate through each section of the original document using a for loop and clone it into the new document.
  • Save the resulting document using the Document.saveToFile() method.
  • Java
import com.spire.doc.*;

public class ReadOneDocument {
    public static void main(String[] args) {
        // Create a new document object
        Document document = new Document();

        // Load a Word document from a file
        document.loadFromFile("Sample.docx");

        // Create a new document object
        Document newdoc = new Document();

        // Clone the default style to the new document
        document.cloneDefaultStyleTo(newdoc);

        // Iterate through each section in the original document and clone it to the new document
        for (Section sourceSection : (Iterable) document.getSections()) {
            newdoc.getSections().add(sourceSection.deepClone());
        }

        // Save the new document to a file
        newdoc.saveToFile("Content of the entire document.docx", FileFormat.Docx);

        // Close and release the new document object
        newdoc.close();
        newdoc.dispose();

        // Close and release the original document object
        document.close();
        document.dispose();
    }
}
