I wonder how you can iterate with an index in a for loop, and to make it even more complex i need this index so i can change the name of the input according to the iterator, such that each row will have a name concated with an incremented number The following of course does NOT work: <CODE> <xsl:variable name="iLineNumber" select="1"/> <xsl:for-each select="table/line"> <tr> <td> <xsl:copy-of select="$strLength"/> <input type="hidden" name=concat("line","$iLineNumber") value="10"/> <input type="text" name=concat("tbRemark","$iLineNumber") size="50" /> </td> </tr> [some sort of: $iLineNumber++] </xsl:for-each> </CODE> Any ideas on how I can achieve some this stuff? Thanks, Marla.

Hi Marla

In XSLT if you need to loop on a counter you have to use a recursive function (http://en.wikipedia.org/wiki/Recursive_function).

In this case you may try to use the position() function as index

<CODE>
<xsl:for-each select="table/line">
<tr>
<td>
<xsl:copy-of select="$strLength"/>
<input type="hidden" name="{ concat(line, position()) }" value="10"/>
<input type="text" name="{ concat(tbRemark, position()) }" size="50" />
</td>
</tr>
</xsl:for-each>
</CODE>

Hope this helps
