Code:
sed 's/==*/==/g' example.xml > example.xml

But after using this command i found, where single character = is there, it changes into ==
Seems to me that this is what you wanted, isn't it?

If you only want to replace two or more occurences of "=" use:

Code:
sed 's/===*/==/g' example.xml > example.xml.result

You cannot direct the output of sed to the input file, because that would overwrite and destroy the input file after the first line. Therefore a different output file name.

I hope this helps.

SYNOPSIS

       xml-xread [options] xmlfile

DESCRIPTION

       xml-xread  is  a simple command line tool for parsing and validating XML documents.  It is not an actual XML parser, it just wraps around a
       JAXP XMLReader, adding support for catalog-based entity and URI resolution.

OPTIONS

       -c catalogfile
	      Load a particular catalog file.  May be specified multiple times.

       -v     Perform a validating parse.  This is the default.

       -w     Perform a well-formed parse, not a validating parse.

       -N     Perform a namespace-aware parse.	This is the default.

       -n     Perform a namespace-ignorant parse.

       -d debuglevel
	      Set the debug level (an integer).  Warnings are shown if the debug level is set to greater than 2.

       -E maxerrors
	      Set the maximum number of errors to display.  The default is 10.

FILES

       /etc/java/resolver/CatalogManager.properties
	      The central catalog manager configuration file used by xml-xread.
