This doesn't look like an ideal job for XSLT, which
generally covers up those things. You could write an
extension function for it. If the list of characters
is suitably small, you could do something like:

<xsl:variable name="charnum"><xsl:choose>
  <xsl:when test="$char = '&#65;'">65</xsl:when>
  <xsl:when test="$char = '&#66;'">66</xsl:when>
  <xsl:when test="$char = '&#67;'">67</xsl:when>
    ...
  <xsl:otherwise>-1</xsl:otherwise>
</xsl:choose></xsl:variable>

Why do you want this, anyway? Perhaps your larger task
can be accomplished in a better way.
