php simplexml xpath问题

嘿，我是 xPath 的新手，时间对我来说很不利，我现在没有时间学习很多相关知识，所以我希望你们能帮助我！ :)

这是我的 xml 格式：

<Filme>
 <Film>
  <filmid>13497</filmid>
  <originaltitel>Bird</originaltitel>
  <originaluntertitel></originaluntertitel>
  <titel>Bird (OmU)</titel>
  <untertitel></untertitel>
  <filmstart>0000-00-00</filmstart>
  <fsk>12</fsk>
 </Film>
</Filme>

这是一些 php 代码，将文档加载到 simplexml 对象中，并进行一些搜索（ $movie_name 变量是作为参数传递给函数的字符串）：

$xml = simplexml_load_file("/somePath/Filme.xml");

//will find all the titles that contains the string $movie_name
foreach( $xml->xpath("//titel[contains(.,'$movie_name')]") as $title){

        //need to find the filmid corresponding to this film title
        //$id = ?????
        $res .= $title."<input type='checkbox' name='movies' value='$id' ><br />";
    }

所以我的问题在代码中评论，当我有 title 元素值时检索 filmid 的 xpath 语法是什么？

原文

Hey, I'm very newbie to xPath and time is against me, I don't have the time right now to learn a lot about it, so I hope you guys can help me with this! :)

Here is my xml format:

<Filme>
 <Film>
  <filmid>13497</filmid>
  <originaltitel>Bird</originaltitel>
  <originaluntertitel></originaluntertitel>
  <titel>Bird (OmU)</titel>
  <untertitel></untertitel>
  <filmstart>0000-00-00</filmstart>
  <fsk>12</fsk>
 </Film>
</Filme>

Here is some php code, loading the document into a simplexml object, and do some search (the $movie_name variable is a string passed as an argument to the function):

$xml = simplexml_load_file("/somePath/Filme.xml");

//will find all the titles that contains the string $movie_name
foreach( $xml->xpath("//titel[contains(.,'$movie_name')]") as $title){

        //need to find the filmid corresponding to this film title
        //$id = ?????
        $res .= $title."<input type='checkbox' name='movies' value='$id' ><br />";
    }

So my question is in the code comments, what is the xpath syntax to retrieve the filmid when I have the titel element value?
