RE: String Manipulation - Distinguishing alphas and nu

Conal,

Thanks! That worked. Here's the result...

XML ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
<para>The completion chemical is <chemical>H2OClF3H4</chemical> for this
test.</para>

XSL ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
<xsl:template match="chemical">
   <xsl:variable name="this_chemical" select="."/>
   <xsl:call-template name="chemical_formater">
     <xsl:with-param name="formula" select="."/>
   </xsl:call-template>
</xsl:template>

<xsl:template name="chemical_formater">
   <xsl:param name="formula"/>
   <xsl:variable name="each_char" select="substring($formula,1,1)"/>
   <xsl:choose>
     <xsl:when test="$each_char='1' or $each_char='2' or $each_char='3' or
$each_char='4' or $each_char='5' or $each_char='6' or $each_char='7' or
$each_char='8' or $each_char='9' or $each_char='0'">
		<fo:inline baseline-shift="sub" font-size="75%">
		   <xsl:value-of select="$each_char"/>
		</fo:inline>
     </xsl:when>
     <xsl:otherwise>
		<fo:inline baseline-shift="normal">
		   <xsl:value-of select="$each_char"/>
		</fo:inline>
     </xsl:otherwise>
   </xsl:choose>
   <xsl:if test="substring-after($formula,$each_char)!=''">
	   <xsl:call-template name="chemical_formater">
		 <xsl:with-param name="formula">
		   <xsl:value-of
select="substring-after($formula,$each_char)"/>
		 </xsl:with-param>
	   </xsl:call-template>
   </xsl:if>
</xsl:template>

XSL-FO ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
<fo:block>
The completion chemical is 
                  <fo:inline baseline-shift="normal">H</fo:inline>
                  <fo:inline baseline-shift="sub"
font-size="75%">2</fo:inline>
                  <fo:inline baseline-shift="normal">O</fo:inline>
                  <fo:inline baseline-shift="normal">C</fo:inline>
                  <fo:inline baseline-shift="normal">l</fo:inline>
                  <fo:inline baseline-shift="normal">F</fo:inline>
                  <fo:inline baseline-shift="sub"
font-size="75%">3</fo:inline>
                  <fo:inline baseline-shift="normal">H</fo:inline>
                  <fo:inline baseline-shift="sub"
font-size="75%">4</fo:inline>
 for this test.</fo:block>

I appreciate the push through the mental block! On to the next challenge.

Kevin

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.
