If it's not XML, you can use regex:
import java.util.regex.*;
String aParser="<con><status>OK</status><session>12312332432</session></con>";
Pattern p=Pattern.compile("<session>(.*)</session>");
Matcher m=p.matcher(aParser);
while(m.find())
{
System.out.println(m.group(1));
}

For XML purposes you should use an XMLParser.
Look at SAXParser it will do the job.
SAXParser is very good when dealing with big files, because the whole document isn´t hold in memory.

its not XML. its just html string

The String you posted can be parsed with an XML Parser.
If you just need session value and not the entire XMl data.just split() the string as below
xmlString.split(starttag)[1].split(endtag)[0];
