I've a sample xml file such as :

我希望使用XQuery语言，但我对这种查询语言非常陌生。
我需要的基础设施是：我想获取章节及其标题的部分，例如：
章节在此xml文件中如下所示：
<chapter id="ecls_bio_becls_a3_a30660983.SL2300626.14" role="-" toctitle="yes" footrowtitle="no" type="security">
<embed-title_module id="ecls_bio_becls_a3_a30660983.SL2361816.15">
<?ecls-start-embedded-resource resource="ecls_bio_becls_a3_a611713"?>
<title_module id="ecls_bio_becls_a3_a611713.SL873735.16" role="-">
<title id="ecls_bio_becls_a3_a611713.SL873736.17">Sicherheits- und Warnhinweise</title>
...
在这个例子中，Sicherheits- und Warnhinweise 是章节元素的标题。章节可以有许多小节，在我们的例子中，小节的标题是:
<section id="ecls_bio_becls_a3_a11752692.SL1742298.19" footrowtitle="no" role="-" toctitle="yes">
<?Pub Caret1?>
<embed-title_module id="ecls_bio_becls_a3_a11752692.SL1742291.20">
<?ecls-start-embedded-resource resource="ecls_bio_becls_a3_a16181733"?>
<title_module id="ecls_bio_becls_a3_a16181733.SL984238.21" role="-">
<title id="ecls_bio_becls_a3_a16181733.SL984239.22">Bevor Sie das Gerat in Betrieb nehmen</title>
...
在启动设备之前。
预期的结构：
<chapter> title:"Chapter's title"
<section>title:"First section's title"</section>
<section>title:"Second section's title"</section>
</chapter>
这个例子只有一个章节，但我刚刚配置了这个章节以找到我的文件解决方案，我认为这是最易读的配置...
我尝试了以下的xquery查询：
<chapter
let $doc := doc("Test.xml")
for $chapter in $doc/user_manual/embed-language_part/language_part/embed-user_manual_part/user_manual_part/embed-chapter/chapter
let $chapter_title := $chapter/embed-title_module/title_module/title
for $section in $chapter/embed-section/section
return <chapter>title:{data($chapter_title)} <section> title:{data($section/embed-title_module/title_module/title)}</section></chapter>
使用两个嵌套的循环，但这段代码使我的结构看起来像：
<chapter>title:"Chapter's title"<section>"First section's title"</section></chapter>
<chapter>title:"Chapter's title"<section>"Second section's title"</section></chapter>
问题是循环的，但当我尝试像这样编辑代码时：
let $doc := doc("assemble.xml")
for $chapter in $doc/user_manual/embed-language_part/language_part/embed-user_manual_part/user_manual_part/embed-chapter/chapter
let $chapter_title := $chapter/embed-title_module/title_module/title
<chapter> title:{data($chapter_title)} {
for $section in $chapter/embed-section/section
return <section> title:{data($section/embed-title_module/title_module/title)}</section>
}</chapter>
我只想在第一个循环中添加 标签，之后再添加查询的部分元素。但是上述命令并没有按照我的期望工作。
因此，我需要您的建议来正确构建这些结构。非常感谢您的帮助。我希望我已经向大家清楚地说明了情况。文件名假定为“assemble.xml”。
