I've to populate a total of 20 elements with XSLT. In my XML code I have a <select> with the values, there is anyway to not to write 20 forms?

My XML:

<output>
    <select>
        <id>1</id>
        <name>One</name>
    </select>
    <select>
        <id>2</id>
        <name>Two</name>
    </select>
    <select>
        <id>3</id>
        <name>Three</name>
    </select>
    <!-- An more -->
</output>

My XSLT:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">   
    <xsl:template match="/">
        <html>

            <body>
        <select name="values[]">
            <option value="0"> </option>
            <xsl:for-each select="output/select">
                <option>
                    <xsl:attribute name="value"><xsl:value-of select="id"></xsl:attribute>
                    <xsl:value-of select="name" />
                </option>
            </xsl:for-each>
        </select>
            </body>

        </html>
    </xsl:template>
</xsl:stylesheet>

Desired output:

<html>
    <body>

        <select name="values[]">
            <option value="0"> </option>
            <option value="1">One</option>
            <option value="2">Two</option>
            <option value="3">Three</option>
        </select>
        <!-- But 20 times -->   

    </body>
</html>

If you have an xml structure with at least $n elements (even nested) in $structure:

<xsl:for-each select="$structure//*[position() < $n]">
   <!-- do whatever you want -->
</xsl:for-each>

Yes, it is hackish, but conceptually easier than a recursive function.
