 Does anyone know how to do this? (the chemistry is not the issue, I realize this is a bogus combination) I don't do FO transformations, but I made this for myself based on what you describe. I'm sure you can modify the <sup> and <sub> elements to be what you need them to be for FO. It turned the above into candybars are made of H<sub>20</sub>ClF<sub>3</sub>. <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:chem="http://www.integretechpub.com/chemistry" extension-element-prefixes="chem"> <xsl:variable name="subMap" select="'0123456789'"/> <xsl:variable name="supMap" select="'+-'"/> <!-- Begin Template: chem:format --> <xsl:template name="chem:format"> <xsl:param name="molecule" select="''"/> <xsl:choose> <xsl:when test="string-length($molecule) = 0"/> <!-- Test for atom count (subscript) --> <xsl:when test="contains($subMap, substring($molecule, 1, 1))"> <xsl:variable name="end-index"> <xsl:call-template name="chem:lastIndexOfConsecutiveChars"> <xsl:with-param name="str" select="$molecule"/> <xsl:with-param name="chars" select="$subMap"/> </xsl:call-template> </xsl:variable> <sub> <xsl:value-of select="substring($molecule, 1, $end-index)"/> </sub> <xsl:call-template name="chem:format"> <xsl:with-param name="molecule" select="substring($molecule, $end-index + 1, string-length($molecule))"/> </xsl:call-template> </xsl:when> <!-- Test for Ion indicator (superscript) --> <xsl:when test="contains($supMap, substring($molecule, 1, 1))"> <xsl:variable name="end-index"> <xsl:call-template name="chem:lastIndexOfConsecutiveChars"> <xsl:with-param name="str" select="$molecule"/> <xsl:with-param name="chars" select="$supMap"/> </xsl:call-template> </xsl:variable> <sup> <xsl:value-of select="substring($molecule, 1, $end-index)"/> </sup> <xsl:call-template name="chem:format"> <xsl:with-param name="molecule" select="substring($molecule, $end-index + 1, string-length($molecule))"/> </xsl:call-template> </xsl:when> <!-- Assume atom identifier (normalscript) --> <xsl:otherwise> <xsl:value-of select="substring($molecule, 1, 1)"/> <xsl:call-template name="chem:format"> <xsl:with-param name="molecule" select="substring($molecule, 2, string-length($molecule)- 1)"/> </xsl:call-template> </xsl:otherwise> </xsl:choose> </xsl:template> <!-- End Template: chem:format --> <!-- Begin Template: chem:lastIndexOfConsecutiveChars --> <xsl:template name="chem:lastIndexOfConsecutiveChars"> <xsl:param name="str" select="''"/> <xsl:param name="chars" select="''"/> <xsl:choose> <xsl:when test="string-length($chars) = 0 or string-length($str) = 0"> <xsl:value-of select="0"/> </xsl:when> <xsl:when test="contains($chars, substring($str, 1, 1))"> <xsl:variable name="result"> <xsl:call-template name="chem:lastIndexOfConsecutiveChars"> <xsl:with-param name="str" select="substring($str, 2)"/> <xsl:with-param name="chars" select="$chars"/> </xsl:call-template> </xsl:variable> <xsl:value-of select="$result + 1"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="0"/> </xsl:otherwise> </xsl:choose> </xsl:template> <!-- End Template: chem:lastIndexOfConsecutiveChars --> <!-- Match all 'chemical' elements -->
