Splitting XML into multiple files with XSLT

I'm having a hard time wrapping my head around XSLT but I heard it's possible to split an XML file into multiple files. Basically I'd like to copy all the elements up to the first file and after the last file and then add the individual file content for each output file.

Could someone give me some pointers on this if it's even possible?

Thanks,

complete.xml

<rootelem>
  <elem>
    <file attr1='1'>
      <content>content file 1</content>
    </file>
    <file attr2='2'>
      <content>content file 2</content>
    </file>
    <file attr3='3'>
      <content>content file 3</content>
    </file>
  </elem>
</rootelem>

OUTPUT:

complete_PART1.xml

<rootelem>
  <elem>
     <file attr1='1'>
        <content>content file 1</content>
     </file>
  </elem>
</rootelem>

complete_PART2.xml

<rootelem>
  <elem>
    <file attr2='2'>
      <content>content file 2</content>
    </file>
  </elem>
</rootelem>

complete_PART3.xml

<rootelem>
  <elem>
     <file attr3='3'>
        <content>content file 3</content>
     </file>
  </elem>
</rootelem>

Responding to your comment on @Dimitre's answer...

You wrote,

<xsl:template match="/">
  <xsl:for-each select="elem/file">
    <xsl:result-document method="xml" href="file_{@id}-output.xml">
      <xsl:copy-of select="."/>
    </xsl:result-document>
  </xsl:for-each>
</xsl:template>

This doesn't quite match your XML, which has rootelem as an outermost element, and your comment says root as an outermost element. You probably want something like this:

<xsl:template match="/root">
  <xsl:for-each select="elem/file">
    <xsl:result-document method="xml" href="file_{@id}-output.xml">
      <root>
        <xsl:copy-of select="/root/@*" />
        <elem>
          <xsl:copy-of select="../@* | ." />
        </elem>
      </root>
    </xsl:result-document>
  </xsl:for-each>
</xsl:template>

You could get fancier, trying to use <xsl:copy> instead of literal result elements for root and elem, but it doesn't seem worth the effort unless they're going to vary.
