  Well <xsl:copy-of puts the complete node element (PRE_HTML and its
text) into the output tree. But right now
  PRE_HTML is child under CONTAINER. What you need find out children of
an element somwehere else in the       document whose name is contained
within this PRE_HTML. 

  Step 1: get the text() associated with PRE_HTML

    <xsl:variable name="preHTML" select="PRE_HTML" />

  Step2 : search for an element whose name is equal to preHTML starting
from the document root  and copy its           child element.
    <xsl:copy-of select="/*[name() = $preHTML]/*">
