Not possible in 1.0 without extensions.

In 2.0:

<xsl:analyze-string select="$in" regex="[A-Za-z]">
  <xsl:matching-substring>
    <xsl:value-of select="format-number(string-to-codepoints(.), '00')"/>
  </xsl:matching-substring>
  <xsl:non-matching-substring>
    <xsl:value-of select="."/>
  </xsl:non-matching-substring>
</xsl:analyze-string>
