Internet / network access for Xerces parser

[Shirish Kulkarni <sh...@yahoo.com>]

Hi, 

I have following queries - 

1. Does Xerces parser require the machine to be on the
network / Internet connection. I verified, that in
processing of a schema/namespace enabled XML file, the
constructor for XMLURL gets called only once ( and the
generated URL is a dummy URL and does not get used for
actual Stream creation ) -> Since the parser is
equipped with an EntityResolver, which points to the
LocalFileInputSorce, the Schema is also used from
local hard disk. 

2. I tried to create a XMLURL say
http://www.yahoo.com/index.html, but
url_input_source.makeStream() is always observed to be
throwing a Malformed URL error -> which checking
found, that XMLPlatformUtils::fgNetAccessor does not
get initialized for sun4_solaris. Is this a bug for
Xerces V 1.5.1 on sun4_solaris ? [ fgNetAccessor
should get initialized during call to
XMLPlatformUtils::Initialize() ] 

  char * url_string = (char
*)"http://www.yahoo.com/index.html" 

  XMLURL xml_url = XMLURL ( url_string );

  URLInputSource url_input_source = URLInputSource (
xml_url );

  try
  {
    BinInputStream * bin_input_steam =
url_input_source.makeStream();
  }
  catch (...)                                         
       
{
  cerr << "caught an exception" ; 
}


3. Is there any standard utility / API in Xerces,
which I can use to find 
  3.1. If the machine is connected to network 
  3.2. If the machien is able to access Internet 

Any guidance will be appreciated.

Thanks,
Shirish
