SimpleXML：将属性放入变量

Question

I am building my website with a central XML-file and SimpleXML. The pages have some different features like the language. I would like to put these features into the XML-file with attributes of the parent node:

<content>
  <item id="one" lang="en">
    <title>Hello</title>
  </item>
</content>

I call a certain item by the id-attribute and I know how to call subnodes like :

$xml = simplexml_load_file('file.xml');
$lang = $bl->xpath('/content/item[@id="one"]/title/text()'); 
   $lang = $lang[0]; echo $lang;

But how do I get the attribute LANG of an item with the id="one" into a variable?

Answer 1

属性/content/item[@id="one"]/@lang的路径属性data(/content/item[@id="one"]/@lang)的值data(/content/item[@id="one"]/@lang)
