and I want it to transform like this

<ce:bib-reference id="bib1">
<ce:label>[1]</ce:label>  
<sb:reference>  
<sb:contribution>
<sb:authors>  
<sb:author>
<ce:given-name>R.F.</ce:given-name>
<ce:surname>Ziolo</ce:surname>
</sb:author>  
<sb:author>
<ce:given-name>E.P.</ce:given-name>
<ce:surname>Giannelis</ce:surname></sb:author>  
</sb:authors>
 </sb:contribution>
<sb:host>
<sb:issue>  
 <sb:series>  

<sb:title><sb:maintitle>Science</sb:maintitle></sb:title>
 
 <sb:volume-nr>257</sb:volume-nr>  
 </sb:series>
 <sb:date>1992</sb:date>
</sb:issue>  
<sb:pages> 
<sb:first-page>219</sb:first-page></sb:pages>
</sb:host>
</sb:reference>
 </ce:bib-reference> 
 
<ce:bib-reference id="bib2">
<ce:label>[2]</ce:label>  
<sb:reference>  
<sb:contribution>
<sb:authors>  
<sb:author>
<ce:given-name>D.</ce:given-name>
<ce:surname>Wirtz</ce:surname>
</sb:author>  
<sb:author>
<ce:given-name>M.</ce:given-name>
<ce:surname>Fermigier</ce:surname>
</sb:author>  
</sb:authors>
</sb:contribution>
<sb:host>
<sb:issue>  
<sb:series>  
<sb:title><sb:maintitle>Phys. Rev.

<sb:volume-nr>72</sb:volume-nr>  
</sb:series>
<sb:date>1994</sb:date>
</sb:issue>  
<sb:pages> 
<sb:first-page>2294</sb:first-page></sb:pages>
</sb:host>
</sb:reference>
</ce:bib-reference>

Could this possible?

It's very difficult for me to transform this XML
because the nodes have the same level (text:p), I
cannot used the <xsl:for-each> or maybe my stylesheet
was wrong.
Can somebody help me with this or any idea how can I
transform it?

regards.
