/**
 * Get the value of meta information writen in the html page. The meta

 * head section with two attributes: id and content. For example:
 * /* w ww  .  j  a  va  2s .c  om*/
 * <code>&lt;meta name="name" value="userName" /&gt;</code>
 *
 * @param name the name
 * @return the value of the attribute 'content' or null if not found
