for loop and use the value - xslt

Question

I've the below line in XML.
<tb class="3">
<tr>
<td>
<b>English words </b>
</td>
<td>
<b>Arabic </b>
</td>
<td al="r">
<b>Arabic</b>
</td>
</tr>
<tr>
<td>bear </td>
<td>ḍam</td>
<td al="r">new</td>
</tr>
</tb>
Here is my xslt.
<xsl:template name="table" match="tb">
<table class="frame-all">
<xsl:call-template name="cols"/>
<xsl:apply-templates/>
</table>
</xsl:template>
<xsl:template name="cols">
<xsl:variable name="numbr" select="number(./#class)"/>
<xsl:variable name="colcnt" select="format-number(100 div $numbr,'##.#')"/>
<colgroup>
<!-- I want the condition here-->
</colgroup>
</xsl:template>
This gives me output of 33.3. And I want to create 3 cols(the class attribute value). And for each col the name should be increment value. as below.
<col name="1" width="33.3"/>
<col name="2" width="33.3"/>
<col name="3" width="33.3"/>
please let me know, how can i get the above result.
Thanks

Here is my answer.
<xsl:template name="table" match="tb">
<table class="frame-all">
<xsl:call-template name="cols"/>
<!--<xsl:apply-templates/>-->
</table>
</xsl:template>
<xsl:template name="colgroup">
<xsl:param name="count" select="./#cls"/>
<xsl:param name="final" select="1"/>
<xsl:variable name="colcnt" select="format-number(100 div number(./#cls),'##.#')"/>
<col class="colnum-{$final} colname-col{$final} colwidth-{$colcnt}"></col>
<xsl:if test="$final < $count">
<xsl:call-template name="colgroup">
<xsl:with-param name="final" select="$final +1"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
<xsl:template name="cols">
<xsl:variable name="numbr" select="number(./#cls)"/>
<xsl:variable name="colcnt" select="format-number(100 div $numbr,'##.#')"/>
<colgroup>
<xsl:call-template name="colgroup"/>
</colgroup>
<xsl:for-each select="tr">
<xsl:apply-templates select="."/>
</xsl:for-each>
</xsl:template>
<xsl:template match="tr">
<tr>
<xsl:apply-templates/>
</tr>
</xsl:template>
<xsl:template match="td">
<td>
<xsl:attribute name="align">
<xsl:choose>
<xsl:when test="./#al='r'">
<xsl:text>right</xsl:text>
</xsl:when>
<xsl:when test="./#al='c'">
<xsl:text>center</xsl:text>
</xsl:when>
<xsl:otherwise>
<xsl:text>left</xsl:text>
</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
<xsl:apply-templates/>
</td>
</xsl:template>

If you are using XSLT 2.0, then one way to generate a specific number of elements, in your case col elements, is to use a variation of the xsl:for-each to do a specific number of iterations.
So, instead of doing <xsl:call-template name="colgroup"/> to call a recursive template, you could do this:
<colgroup>
<xsl:for-each select="1 to xs:integer($numbr)">
<col name="{.}" width="{$colcnt}"/>
</xsl:for-each>
</colgroup>
Note that you will need to define the xs namespace prefix in your stylesheet as follows
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
