XSL : Look up for XSL command retrieve an XML nodes list

Question

Is there in the XSL commands, a tool to retrieve a list of nodes ex :

<Root>
    <Params>
      <First>1</First>
      <Second>2</Second>
      <Group>
        <Data>Example</Data>
        <Info>Show</Info>
      </Group>
    </Params>
</Root>

so , <XSL:[Command] select="/Root/Params"/> will give :

<Params>
  <First>1</First>
  <Second>2</Second>
  <Group>
    <Data>Example</Data>
    <Info>Show</Info>
  </Group>
</Params>

Answer 1

<xsl:copy-of select="/Root/Params"/>

will do that (probably, since the context is not entirely clear).
