Hai, I have the xslt coding for convert the xml file to fo file for xml to word conversion, in this <fo:inline xmlns:fo="#unknown">contains <fo:inline> as child both are different formats.

sample xml

<sub>ALT</sub>
 (<sub><italic>S</italic></sub> b).

<xsl:template match="//sub">
<fo:inline baseline-shift="sub">
<xsl:apply-templates/>
</fo:inline>
</xsl:template>



<xsl:template match="//italic">
<fo:inline font-style="italic">
<xsl:apply-templates/>
</fo:inline>
</xsl:template>

in this _{<italic>S</italic>} reflect only the italic, subscript not reflected , anyone have the solution.
