RE: String Manipulation - Distinguishing alphas and numerics in a string

You need to write a template with a name attribute, and call it to process
the string. Pass the string to it as a parameter. This template would handle
the first part of the string, then if there's any string remaining, it
should call itself, passing itself the remainder of the string.

XML source:
<para>candybars are made of <chemical>H20ClF3</chemical>.</para>


XSL needed?????
<xsl:template match="chemical">
  <xsl:variable name="this_chemical" select="."/>

<!-- This is the part I'm stuck on. How do I process the string? The

the string and wrap each number with the FO for subscript? -->

</xsl:template>

XSL-FO desired:

<fo:block>water is made of H<fo:inline baseline-shift="sub"
2</fo:inline>OClF<fo:inline baseline-shift="sub"
3</fo:inline>.</fo:block>
