XSLT using namespace inside the root element

Ia m trying to create a XSLT file for the below xml.

<?xml version="1.0" encoding="utf-8"?>
<items>

  <ListedItemDetail xmlns="http://test.com/v1" xmlns:i="http://ift.tt/ra1lAU">
    <ListingId>797188526</ListingId>
 </ListedItemDetail>

 <ListedItemDetail xmlns="http://test.com/v1" xmlns:i="http://ift.tt/ra1lAU">
    <ListingId>7971823</ListingId>
</ListedItemDetail>

</items>

And below is the XSLT file i have created

<xsl:stylesheet version="2.0" xmlns:xsl="http://ift.tt/tCZ8VR"   xmlns:xsi="http://ift.tt/ra1lAU"  xmlns:t="http://test.com/v1" >

    <xsl:template match="items">
            <xsl:element name="ListedItemDetail">
                <xsl:element name="ListingId">
                    <xsl:value-of select="ListingId"/>
                </xsl:element>

but I can't get it to work for the life of me. Can someone tell me what I am doing wrong?

Thanks,
