[SOLVED] How to get elements from XPath in Java

How to get elements from XPath in Java

I want to get data from an XPath query:

Element location = (Element) doc.query("//location[location_name='"+ locationName +"']/*").get(0).getDocument().getRootElement();
System.out.println(location.toXML());

Element loc = location.getFirstChildElement("location");
System.out.println(loc.getFirstChildElement("location_name").getValue());

However, no matter what I choose, I always get 1 node (because of .get(0)). I don't know how to select the node which was selected by query.

I found that I should cast the node to Element, (XOM getting attribute from Node?) but the link only shows how to select the first node.

Solution

Call getParent() on the first element in the result:

Builder parse = new Builder();
Document xml = parse.build("/var/www/JAVA/toForum.xml");

System.out.println(xml.query("//location[@id=83]/*").get(0).getParent().toXML());

Produces the following output:

<location id="83">
  <location_name>name</location_name>
  <company_name>company a</company_name>
  <machines>
    <machine id="12">A</machine>
    <machine id="312">B</machine>
  </machines>
</location>
