Passing parameters through HTML buttons

Is there a way to do this?

This is what I currently have:

<xsl:element name="a">
    <xsl:attribute name="href">InfoServlet?name=<xsl:value-of select="$vPrev_id"/></xsl:attribute>Previous Event
</xsl:element>

Is there a way to make this a button instead of a text link? I've tried a few things but can't seem to get it to work. I've tried this for example:

<form action="InfoServlet">
    <input class="btn btn-default btn-lg" type="submit" value="View Reviews"/>
    <xsl:attribute>InfoServlet?name=<xsl:value-of select="$name"/></xsl:attribute>
</form>
