If I had such a transformation to perform, I would simply do it like this :
<xsl:template match="math[code='LaTeX'"]>
     <xsl:value-of select="lib:latex2mathml( . )"/>
<xsl:template>
or even if you don't know how to bind a function library to your XSLT 
processor :
<xsl:template match="math[code='LaTeX'"]>
     <xsl:value-of select="document( concat( 
'http://my.rest.service/latex/2/mathml?code=', . ) )"/>
<xsl:template>

Nobody said that XSLT must be standalone, and I'm sure it's easy to find 
a converter for LaTeX.
As you combined some XML tags with LaTeX, why not using both tools and 
make a smart bridge between them ?
