Template Match on a xml tag with a namespace

I am doing xslt transformation on a sample xmldoc using the xslt below. The problem I am having is its not matching on 'Publication'. If I remove the namespace it works fine. Is there a way to get the match on the 'Publication' tag with the namespace?

----Sample XML------

Code:

---

<?xml version="1.0" encoding="utf-8"?>
<Publication xmlns="http://www.mycompany.com/Sampleproject/XmlSchema">
  <PublicationDetails>
    <AgencyId>1</AgencyId>
    <PublicationId>PublicationId1</PublicationId>
    <PublicationDateTime>1900-01-01T01:01:01-07:00</PublicationDateTime>
    <OriginatingSystemName>OriginatingSystemName1</OriginatingSystemName>
    <DestinationSystemName>DestinationSystemName1</DestinationSystemName>
</Publication>

---

---- Sample Xslt ------

Code:

---

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
  <xsl: output method="xml" indent="yes"/>

  <xsl:template match="@* | node()">
    <xsl:copy>
      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="Publication">
      <xsl:apply-templates select ="PublicationDetails"/>
  </xsl:template>
 
 
  <xsl:template match="PublicationDetails">
    <SubmittingAgency>
    </SubmittingAgency>
  </xsl:template>
 
</xsl:stylesheet>
