I think that rather than using xsl:analyze-string to analyze the value of
regex-group(5), I would use a sequence of calls on matches():

<xsl:variable name="fname" select="regex-group(5)"/>
<xsl:choose>
  <xsl:when test="matches($fname, 'b$')">...
  <xsl:when test="matches($fname, 'm$')">...
  <xsl:otherwise>...
