Question

I have an XML file with this structure:

<?xml version="1.0">
<person>
    <element att1="value1" att2="value2">Anonymous</element>
</person>

How can I extract the attributes names and values using wathever you want.

I tried JDOM, but I still can’t find a way to get the attributes from the element.

Element root = doc.getRootElement();
List allChildren = root.getChildren();
Iterator i = listEtudiants.iterator();
while(i.hasNext())
{
    Element current = (Element)i.next();
    System.out.println(current.getChild("elementName").getText());
    // this let me get just the value inside > anf </
    // so, if it's can be done by completing this code
    // it will be something like current.getSomething()
}

EDIT: I’m still having a problem with this file. I can’t reach foo attribute and its value moo.

<?xml version="1.0" encoding="UTF-8"?>
<person>
   <student att1="v1" att2="v2">
      <name>Michel</name>
      <prenames>
         <prename>smith</prename>
         <prename>jack</prename>
      </prenames>
   </student>
   <student classe="P1">
      <name foo="moo">superstar</name>
   </student>
</person>

Answer 1

If you do know the name of the attribute, then you can use getAttributeValue to obtain its value:

current.getAttributeValue("att1"); // value1

If you do not know the name of the attribute(s), then you can use getAttributes() and iterate over each Attribute:

List attributes = current.getAttributes();
Iterator it = attributes.iterator();
while (it.hasNext()) {
  Attribute att = (Attribute)it.next();
  System.out.println(att.getName()); // att1
  System.out.println(att.getValue()); // value1
}
