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
