Problem with xmlread() and https

Hi,

I want to parse a xml with using xmlread from a url which uses https protocol. I get the following problem : java.io.IOException: Server is not responding, it might not support the current protocol. Missing ServerHello. What can I do to fix this? I am using Matlab R2010a (64 bit) and I have Windows 7 (64 bit). Thnak you in advance.

This could work if you have write access to the file: In command window, type

edit callSoapService

Then in the m-file, search for line

url = URL(endpoint);

Replace it with:

url = URL([], endpoint, sun.net.www.protocol.https.Handler)

Save and try again.

If that doesn't work, you could get the XML text in a string and parse that using undocumented MATLAB . Put the XML in a string by using the http protocol and webread:

% Use http protocol instead of https.
myUrl = regexprep(myUrl, 'https', 'http');

% Read the file into a string.
xmlString = webread(myUrl);

% From undocumented MATLAB:
try
  % The following avoids the need for file I/O:
  inputObject = java.io.StringBufferInputStream(xmlString);  % or: org.xml.sax.InputSource(java.io.StringReader(xmlString))
  try
      % Parse the input data directly using xmlread's core functionality
      parserFactory = javaMethod('newInstance','javax.xml.parsers.DocumentBuilderFactory');
      p = javaMethod('newDocumentBuilder',parserFactory);
      xmlTreeObject = p.parse(inputObject);
  catch
      % Use xmlread's semi-documented inputObject input feature
      xmlTreeObject = xmlread(inputObject);
  end
catch
  % Fallback to standard xmlread usage, using a temporary XML file:
  % Store the XML data in a temp *.xml file
  filename = [tempname '.xml'];
  fid = fopen(filename,'Wt');
  fwrite(fid,xmlString);
  fclose(fid);

    % Read the file into an XML model object
    xmlTreeObject = xmlread(filename);

    % Delete the temp file
    delete(filename);
end
