Aspose.Words - Process Comments

Below you can see example code to extract comments, delete a specific comment and delete all comments.

Ruby Code

def initialize()

    # The path to the documents directory.
    data_dir = File.dirname(File.dirname(File.dirname(__FILE__))) + '/data/'

    # Open the document.
    doc = Rjb::import('com.aspose.words.Document').new(data_dir + 'TestComments.doc')

    # Get all comments from document
    extract_comments(doc)

    # Remove comments by the "pm" author.
    remove_comment($doc, "pm");
    puts "Comments from 'pm' are removed!"

    # Remove all comments.
    remove_comments(doc)
    puts "All comments are removed!"

    # Save the document.
    doc.save(data_dir + "TestComments Out.doc")    
end    
def extract_comments(doc)

    # Call method
    collected_comments  = Rjb::import('java.util.ArrayList').new

    # Collect all comments in the document
    node_type = Rjb::import('com.aspose.words.NodeType')
    comments = doc.getChildNodes(node_type.COMMENT, true).toArray()
    save_format = Rjb::import('com.aspose.words.SaveFormat')
    comments.each do |comment|
        author = comment.getAuthor()
        date_time = comment.getDateTime()
        format = comment.toString(save_format.TEXT)
        puts "Author:" + author.to_s + " DateTime:" + date_time.to_string + " Comment:" + format.to_s
    end
end
def remove_comment(doc, author_name)
    raise 'author_name not specified.' if author_name.empty?

    # Collect all comments in the document
    node_type = Rjb::import('com.aspose.words.NodeType')
    comments = doc.getChildNodes(node_type.COMMENT, true)
    comments_count = comments.getCount()

    # Look through all comments and remove those written by the authorName author.
    i = comments_count
    i = i - 1
    while (i >= 0) do
        comment = comments.get(i)
        author = comment.getAuthor().chomp('"').reverse.chomp('"').reverse
        if (author == author_name) then
            comment.remove()
        end
        i = i - 1
    end
end
def remove_comments(doc)

    # Collect all comments in the document
    node_type = Rjb::import('com.aspose.words.NodeType')
    comments = doc.getChildNodes(node_type.COMMENT, true)
    comments.clear()
end
