Controlling number of occurrences

 Is it possible (using xsl) to limit any repeat occurences of exact strings
of text to one, so that I could use the following template to output a page
that shows all *scripts and filenames* for a particular character. Right
now, obviously, the character data is repeated. The XML I am pulling data
from is a merged file of all of the XMLs for a particular project.
Thank you,

Jennifer



<xsl:for-each select="//audio">

<xsl:sort select="character" order="ascending" data-type="text"/>

<tr>

<td align="center" valign="top" colspan="2"><xsl:apply-templates
select="character"/></td>

</tr>

<tr>

<td align="left" valign="top" width="150"><xsl:apply-templates
select="@filename"/></td>

<td align="left" valign="top" width="450"><xsl:apply-templates
select="script"/></td>

</tr>

</xsl:for-each>

</table>

</xsl:for-each>
