Remove Carriage Return (CRLF) within double quotes

How to remove Carriage Return (CRLF) within double quotes in a file. There are multiple CRLFs within double quotes. We are on Ubuntu 14.04.2 LTS.

The file that we are importing is a csv file from unix to windows and the file was formatted to unix2dos. Therefore all lines in the file all have CRLF at the end. However, there is a comment field where we see multiple CRLFs within this single field and the contents of the field is enclosed with double quotes. So, when we open the file in notepad it looks like a single line is broken into several lines. If the file is opened in the excel it comes out OK.

My requirement is to replace all CRLFs within double quotes should be replaced by a single space.

";

	      echo htmlspecialchars_decode($str);

	      // note that here the quotes aren't converted
