Extract tables from Microsoft Office Word documents

To extract tables from Microsoft Office Word document getStructure method is used. This method returns XML representation of the document. Tables are represented by “table” tag. For more details, see Extract text structure.

Here are the steps to extract tables from Microsoft Office Word documents:

The following example demonstrates how to extract tables from Microsoft Office Word document:

// Create an instance of Parser class
try (Parser parser = new Parser(Constants.SampleDocx)) {
    // Extract text structure to the XML reader
    Document document = parser.getStructure();
    // Read XML document
    readNode(document.getDocumentElement());
}

private static void readNode(Node node) {
    NodeList nodes = node.getChildNodes();
    // Iterate over the child nodes
    for (int i = 0; i < nodes.getLength(); i++) {
        Node n = nodes.item(i);
        // If it's a table
        if (n.getNodeName().toLowerCase() == "table") {
            System.out.println("table");
            // Process node
            processNode(n);
        }
        readNode(n);
    }
}
private static void processNode(Node node) {
    NodeList nodes = node.getChildNodes();
    // Iterate over the child nodes
    for (int i = 0; i < nodes.getLength(); i++) {
        Node n = nodes.item(i);
        switch (n.getNodeName().toLowerCase()) {
            // In the case of a row or cell
            case "tr":
            case "td": {
                // Print the name
                System.out.println(n.getNodeName());
                // Process sub-nodes
                processNode(n);
                System.out.println();
                System.out.println("/" + n.getNodeName());
                break;
            }
            default:
                // Print the node value (if it's not null)
                String value = n.getNodeValue();
                if(value != null) {
                    System.out.print(value);
                }
                processNode(n);
                break;
        }
    }
}
