How to replace unwanted junk while writing html text to word document

iam getting html text in stringbuilder and we are writing tht stringbuilder(html content) into word document…

stringbuilder osb = new stringbuilder;
oDocBuilder = new DocumentBuilder(oCurrentDoc);
oDocBuilder.Writeln(osb.ToString());

My problem is how to replace any unwanted junk,spaces,characters…still anything junk in html content…

Hi
Thanks for your request. I do not fully understand why you are using Writeln method here. I think, in your case you can try using InsertHtml method. You can find an example here:
