<xsl:copy-of select="text[child::*]" />

that selects the text element, if it has an element child.
you want the element children of text so that's
<xsl:copy-of select="text/child::*" />
or more simply
<xsl:copy-of select="text/*" />
if <text> may have text as well as element children you may want to
replace * by node() in either of the above forms.
