This is a summary. It just depends how many you want to copy over.

  1. If you only want to copy a few, then disable all default templates and only write the copy templates for those you want to copy.
  2. If you want to copy all but exclude a few, then use identity template, and only disable a few templates for those you want not to copy.
  3. How to disable some templates? Simple:
    <xsl:template match="tag1_to_disable|tag2_to_disable" />
    
  4. How to write identity template?
      <xsl:template match="*|@*|comment()|processing-instruction()|text()">
        <xsl:copy>
          <xsl:apply-templates select="*|@*|comment()|processing-instruction()|text()"/>
        </xsl:copy>
      </xsl:template>
    
  5. What is copy templates?
    <xsl:template match="tag1_to_copy|tag2_to_copy" >
      <xsl:copy-of select="." />
    </xsl:template>
    
    Attention, this will copy it and its decendents.
Jan Matèrne also gave a good example here.
