Parsing special characters like '&'

I need to create xml document from string. if the text
contains special characters like '&' it throws error.
is there any solution for this... 
may be some special feature that i can set for the
parser.

Tom,

A little method like this can maybe fix your
problem.  It processes a raw string into an
XML-compatible one:


String xmlString(String val)
{
  if (val==null)
    return val;
  StringBuffer buf = new StringBuffer();
  for (int i=0;i<val.length();i++)
      {
      char ch = val.charAt(i);
      if (ch=='&')
        buf.append("&amp;");
      else if (ch=='<')
        buf.append("&lt;");
      else if (ch=='>')
        buf.append("&gt;");
      else if (ch=='\'')
        buf.append("&apos;");
      else if (ch=='"')
        buf.append("&quot;");
      else
        buf.append(ch);
      }
  val=buf.toString();
  return val;
}



It will turn something like

"Rock & roll"

into

&quot;Rock &amp; roll&quot;






Hope this helps.
