Another <xsl:key> problem

 hi all,
   I have a problem with <xsl:key>, here is my xml and
sample output.

<root>
       <text:p>
              <bookmark-start id="bib1"/>
              <user-field
name="bib-reference">Ref</user-field>
       </text:p>
       <text:p>
              <user-field
name="sb:reference">BB</user-field>
       </text:p>
       <text:p>
              <user-field
name="sb:contribution">Contribution</user-field>
       </text:p>
       <text:p>
              <user-field
name="sb:authors">Authors</user-field>
       </text:p>
       <text:p>
               <user-field

               <user-text>A.</user-text>
               <user-field

       </text:p>
       <text:p>
                <user-field

                <user-text>Science</user-text>
       </text:p>
       <text:p>
                <user-field
name="sb:volume-nr">Volume-nr</user-field>
                <user-text>12</user-text>
       </text:p>
       <text:p>
                <user-field
name="sb:date">Date</user-field>
                <user-text>1988</user-text>
                <bookmark-end id="bib1"/>
       </text:p>
...............
</root>

output:
<bib-reference id="bib1">  
    <sb:reference>
        <sb:contribution>
            <ce:authors>
                <ce:author>
                         
<sb:given-name>A.</sb:given-name>
                         
<sb:surname>Andrade</sb:surname>
                </ce:author>
            </ce:authors>
        <sb:title>Mathematics</sb:title>
        </sb:contribution>
        <sb:host>
            <sb:issue>
                <sb:series>

                    <sb:volume-nr>12</sb:volume-nr>
                </sb:series>
            <sb:date>1988</sb:date>
            </sb:issue>
        </sb:host>
    </sb:reference>
 </bib-reference>  
.....................

my problem is, I want to create an index containing
all the nodes from <bookmark-start> to <bookmark-end>
with their corresponding id's, then from that,
separate all the nodes from <bb> to <host> then from
<host> to <date>. I used <xsl:key> to create an index
for that, then used the <xsl:for-each> to process all
the nodes for every  key that I created, is my
declaration with <xsl:key> and key() correct?

    <xsl:key name="bookmark_start"
match="text:bookmark-start" use="@id"/>
    <xsl:key name="bookmark_end"
match="text:bookmark-end" use="@id"/>
   
    <xsl:key name="contribution"
match="text:user-field-get" use="@name"/>
    <xsl:key name="h_issue"
match="text:user-field-get" use="@name"/>

<xsl:template match="bookmark-start">

        <xsl:variable name="begin1" 
select="key('bookmark_start',concat('bib',
$bib_number))[1] /ancestor-or-self::text:p[1]"/>
        <xsl:variable name="end1"    
select="key('bookmark_end',concat('bib',
$bib_number))[1]/ancestor-or-self::text:p[1]"/>      

        <xsl:variable name="biblio" 
select="($begin1/following-sibling::node()|$begin1)[(.|following-sibling::*)[generate-id()=generate-id($end1)]]"/>

        <xsl:variable name="contrib_start" 
select="key('contribution','sb:contribution')[$biblio]/ancestor-or-self::text:p[$bib_number]"/>
        <xsl:variable name="contrib_end"  
select="key('contribution','sb:issue')[$biblio]/ancestor-or-self::text:p[$bib_number]"/>
     
        <xsl:variable name="contrib_sample" 
select="($contrib_start/following-sibling::node()|$contrib_start)[(.|following-sibling::*)[generate-id()=generate-id($contrib_end)]]"/>
 

        <xsl:variable name="begin" 
select="key('h_issue','sb:issue')[$bib_number]
/ancestor-or-self::text:p[$bib_number]"/>
        <xsl:variable name="end"    
select="key('h_issue','sb:date')[$bib_number]/ancestor-or-self::text:p[$bib_number]"/>
     
        <xsl:variable name="sample" 
select="($begin/following-sibling::node()|$begin)[(.|following-sibling::*)[generate-id()=generate-id($end)]]"/>
 

       <xsl:for-each  $biblio
                    <xsl:for-each $contrib_sample
                    </xsl:for-each>
                    <xsl:for-each $sample
                    </xsl:for-each>
       </xsl:for-each>

  </xsl:template>

thanks and regards.
