My xsl snippet looks  like this:
<root>
<years>
    <yearl>
        <year>2004</year>
        <period>prior</period>
    </yearl>
    <yearl>
        <year>2005</year>
        <period>prior</period>
    </yearl>
</years>
</root>

I am taking this as input and using xslt to render my page. I want to send all the years to my form.The code looks like:

<form method="POST" action="test.jsp" id="tes">
----
--
 <xsl:for-each select="/ROOT/years/yearl">
     <input type="hidden" name="years[]" id="years[]" value="{/ROOT/years/yearl/@year}" />
--
--
</xsl:for-each>
--
</form>

This is my javascript function which is being called on hitting save button

function alert{

              var year = [document.getElementById('years')];
             var y = year.length  ;                        
                           
                            if (confirm("The year is  " + year[1].value+ " you still want to save?")) {
                                    document.getElementById(test').submit();
                                }

}

In this function I want to get the list of all the years and do some validation based upon that. But this does not seem to work. PLease help!

@Proculopsis: the years are dynamic and they come from the xsl file. How can I send this dynamic array to the form (the values are not hard coded)? In my javascript code, can I use "get element by id" to get the value of this dynamic array?

function alert{

              var year = [document.getElementById('years')];
             var y = year.length  ;                        
                           
                            if (confirm("The year is  " + year[1].value+ " you still want to save?")) {
                                    document.getElementById(test').submit();
                                }

}

<!-- You can use a transfrom to inject the values -->
<?xml version='1.0' encoding='ISO-8859-1'?>
<xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>
    <xsl:template match='/'>

        <xsl:for-each select='root/years/yearl'>

            <input>
                <xsl:attribute name="value">
                    <xsl:value-of select='year' />
                </xsl:attribute>
            </input>            

      </xsl:for-each>

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