Output of Following-Sibling or Preceding Sibling

Dear David:

   Thanks for your explanations.  It must have been my erroneous typo before with the STAMPS.  The line with $ad should have been

    let $ad2 := $ad//ad/head[contains(upper-case(.), 'MUSCLES')]

   For the $pb variable, it turned out that if I do

   let $pb := $nodes/preceding::pb[1]

from my XQuery:

let $ad := fn:collection("xmldb:exist://db/my")
let $journal := $ad//seriesStmt/title[@level='journal'][1]
let $ad2 := $ad//ad/head[contains(upper-case(.), 'MUSCLES')]
let $sorted_result:=
for $doc in distinct-values($ad2)
order by $doc
return $doc
for $r at $count in $sorted_result
let $nodes := $ad2[. = $r][1]
let $para := $nodes/parent::p[1]
let $head := $nodes/ancestor::ad//head[1]
let $note := $nodes/ancestor::ad//note[1]
let $seriesStmt:=$nodes/ancestor::my//seriesStmt
let $pb := $nodes/preceding::pb[1]
return
<ad>
<statistics>
Showing Result: {$count} / {count($sorted_result)}
</statistics>
<source>
<journal>{data($journal)[1]}</journal>
<publication_information>Volume {data($seriesStmt/idno[@type='volume'][1])},
Issue {data($seriesStmt/idno[@type='issue'][1])}</publication_information>
</source>
{$head}
{$nodes}
<description>{$para}</description>
<information>Source from page {$pb}</information>
{$note}</ad>

Brings this:

<ad>
<statistics> Showing Result: 1 / 1</statistics>
<source>
<journal>My Collection</journal>
<publication_information>Volume 1 , Issue 1 </publication_information>
</source>
<head type ="main">FREE POWERFUL MUSCLES FAST</head>
<head type ="main">FREE POWERFUL MUSCLES FAST</head>
<description/>
<information>Source from page
     <pb n="2" xml:id="my000110"/></information>
<note>Dept. P</note>
</ad>

   This does bring the accurate pb variable that I want. However, when I only have one line of <head> in my original source, it brings back twice with the same content. When I have something like

<head type ="main">FREE POWERFUL MUSCLES FAST</head>
<head type ="sub">FREE POWERFUL MUSCLES FAST</head>

  then the above errors do not occur. I have declared that I only wanted

let $head := $nodes/ancestor::ad//head[1]

Is there something wrong with my <head> declaration here? Here is my XML again:

<my>
    <myHeader>
        <fileDesc>
            <titleStmt>
                <title>My Collection</title>
            </titleStmt>
            <sourceDesc>
                <biblFull>
                    <seriesStmt>
                        <title level="journal">My Journal</title>
                        <idno type="volume"> 1 </idno>
                        <idno type="issue"> 1 </idno>
                    </seriesStmt>
                </biblFull>
