title: formatting of a date in the format of mmm yy to yymm using xslt
body: <p>I need to convert a date in xslt to another format.
  the incoming data is "Feb 18" and the formatted date should be "1802". I know i need to parse the data first into a datetime and then convert it. but it is not recognizing the format.</p>
  
  <pre><code>&lt;xsl:variable name="dt" as="xs:date" select="xs:date(period)"/&gt;
  perio&gt;&lt;xsl:value-of select="$dt"/&gt;&lt;/perio&gt;
  </code></pre>
  
  <p>Thanks to help.
