Question

I have several nodes (see below). I know how to select specific nodes which have a certain attribute. But in this case I would like to import the “file_url” value of the media objects that belong to the group “narrowImage”.

<media_object>

 <media_object>
  <file_id>5175967</file_id>
  <group>wideImage</group>
  <file_url>http://www.mysite.com/image1.jpg</file_url>
 </media_object>

 <media_object>
  <file_id>5175968</file_id>
  <group>wideImage</group>
  <file_url>http://www.mysite.com/image2.jpg</file_url>
 </media_object>

 <media_object>
  <file_id>5175969</file_id>
  <group>narrowImage</group>
  <file_url>http://www.mysite.com/image3.jpg</file_url>
 </media_object>

</media_object>

In the above case i would only need the value “http://www.mysite.com/image3.jpg”

any xpath expert out there who can point me in the right direction?

Answer 1

Use:

/*/*[group = 'narrowImage']/file_url

This selects any file_url element that is a “grand-child” of the top element in the XML document, and whose parent has a group child-element whose string value is 'narrowImage'.
