XQuery FLWOR + HTML

XML 实例文档

我们将在下面的例子中继续使用这个 "books.xml" 文档（与上一节中的文件相同）。

ka fari a browser na iya kama "books.xml" daki:。

a fari cikakken aiki a HTML listu

ka kama XQuery FLWOR expression na kasa:

for $x in doc("books.xml")/bookstore/book/title
koyi $x
return $x

expression na kasa na a yi bookstore elementu kuma book elementu kuma a yi title elementu, a kuma kama aiki bayan aiki na title elementu.

a hali na yau, a na ga a yi HTML listu a fari bayan kowa bukewa a gaskiya. a na kama <ul> da <li> a FLWOR expression:

<ul>
{
for $x in doc("books.xml")/bookstore/book/title
koyi $x
return <li>{$x}</li>
}
</ul>

wurin aiki na koda:

<ul>
<li><title lang="en">Everyday Italian</title></li>
<li><title lang="en">Harry Potter</title></li>
<li><title lang="en">Learning XML</title></li>
<li><title lang="en">XQuery Kick Start</title></li>
</ul>

a hali na amata a title tasi, a kuma fari gaskiya bayan a data tasi.

<ul>
{
for $x in doc("books.xml")/bookstore/book/title
koyi $x
return <li>{data($x)}</li>
}
</ul>

结果将是一个 HTML 列表：

<ul>
<li>Everyday Italian</li>
<li>Harry Potter</li>
<li>Learning XML</li>
<li>XQuery Kick Start</li>
</ul>
