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:

  • Instantiate Parser object for the initial document;
  • Call GetStructure method and obtain XmlReader object;
  • Iterate through the XML document.

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

// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
    // Get the reader object for the document XML representation
    using (XmlReader reader = parser.GetStructure())
    {
        // Iterate over the document
        while (reader.Read())
        {
            // Check if this is the start of the table
            if (reader.IsStartElement() && reader.Name == "table")
            {
                // Process the table
                ProcessTable(reader);
            }
        }
    }
}
 
private static void ProcessTable(XmlReader reader)
{
    Console.WriteLine("table");
    // Create an instance of StringBuilder to store the cell value
    StringBuilder value = new StringBuilder();
    // Iterate over the table
    while (reader.Read())
    {
        // Check if the current tag is the end of the table
        bool isTableEnd = !reader.IsStartElement() && reader.Name == "table";
        // Check if the current tag is the start of the row or the cell
        bool isRowOrCellStart = reader.IsStartElement() && (reader.Name == "tr" || reader.Name == "td");
        // Print the cell value if this is the end of the table or the start of the row or the cell
        if ((isTableEnd || isRowOrCellStart) && value.Length > 0)
        {
            Console.Write("  ");
            Console.WriteLine(value.ToString());
            value = new StringBuilder();
        }
        // If this is the end of the table - return to the main function
        if (isTableEnd)
        {
            return;
        }
        // If this is the start of the row or the cell - print the tag name
        if (isRowOrCellStart)
        {
            Console.WriteLine(reader.Name);
            continue;
        }
        // If this code line is reached then this is the value of the cell
        value.Append(reader.Value);
    }
}
