XML : Removing a parent element in xml while keeping it's children using xslt

I want to transform the following xml,

  <pets>      <Pet>          <category>              <id>4</id>              <name>Lions</name>          </category>          <id>9</id>          <name>Lion 3</name>          <photoUrls>              <photoUrl>url1</photoUrl>              <photoUrl>url2</photoUrl>          </photoUrls>          <status>available</status>          <tags>              <tag>                  <id>1</id>                  <name>tag3</name>              </tag>              <tag>                  <id>2</id>                  <name>tag4</name>              </tag>          </tags>      </Pet>  </pets>    

in to this xml format.

  <pets>      <Pet>          <category>              <id>4</id>              <name>Lions</name>          </category>          <id>9</id>          <name>Lion 3</name>          <photoUrl>url1</photoUrl>          <photoUrl>url2</photoUrl>          <status>available</status>          <tag>              <id>1</id>              <name>tag3</name>          </tag>          <tag>              <id>2</id>              <name>tag4</name>          </tag>      </Pet>  </pets>    

I tried to write a template as follows, but it removes the parent element with it's children.

  <xsl:template match="photoUrls"/>    

How can this be done in xslt. Any help is appreciated.
