RE: [xsl] A tricky problem

["Carlos M. S. Bento Nogueira" <cmsbn@xxxxxxxxxxxxxxxxx>]

Everybody,please forgive me for this double post,the fact is that i 
replied correctly but to wrong question previously :(

Aron,
the reason why this code you suggest doesn't work is that my inputs 
are declared as
<input type="radio" id="{generate-id()}" name="{$id}" value="{@value}">
and the generate-id() functions probably loses reference to the context 
node when used inside the <xsl:template
match="opt">(now fi:item) as you suggested.

I adapted your snippets to produce this:
<xsl:for-each select="fi:selection-list/fi:item[position() &lt;= 
current()/$line]">
<xsl:variable name="r" select="position() - 1"/>
        <tr>
        <xsl:apply-templates select="fi:item[position() &gt;= $r * $column + 1
        and position() &lt;= $r * $column + $column ]"/>
        </tr>
</xsl:for-each>
(...)

<xsl:template match="fi:item">
        <td>
        <input type="radio" id="{generate-id()}" name="{$id}" value="{@value}">
        (...)
</xsl:template>

Also the output i'm trying to achieve is e.g. for a table with 2 lines and 
2 columns is

<td>
        <input>
</td>
<td>
        <input>
</td>
<tr>    <!--I can only have (($number_of_lines) - 1) tr tags -->
<td>
        <input>
</td>
<td>
        <input>
</td>
</tr>

TIA, TG(thanks again),
CarlosN.
