Get only specific element node from xml using stax parser

Question

<xml>
<name>steve</name>
<age>12</age>
<country>Germany</country>
<person>
  <college>kmu university</college>
  <country>Sweden</country>
</person>
</xml>

Using stax parser while parsing I get country name as Germany,Sweden. But I need only Sweden not germany. Any other way to get it.I am using STAX parser to parse this xml.

Expected Output: Sweden

Actual Output:Germany,Sweden

When you do StAX (and SAX) parsing, you need to track the context yourself. this means you need to keep track of the elements which have started and not yet completed. once you have this information, you can then keep only the "country" element which is nested under the "person" element and ignore all other "country" elements.
