Getting XML Node text value with Java DOM

I can't fetch text value with Node.getNodeValue(), Node.getFirstChild().getNodeValue() or with Node.getTextContent().

My XML is like

<add job="351">
    <tag>foobar</tag>
    <tag>foobar2</tag>
</add>

And I'm trying to get tag value (non-text element fetching works fine). My Java code sounds like

Document doc = db.parse(new File(args[0]));
Node n = doc.getFirstChild();
NodeList nl = n.getChildNodes();   
Node an,an2;

for (int i=0; i < nl.getLength(); i++) {
    an = nl.item(i);

    if(an.getNodeType()==Node.ELEMENT_NODE) {
        NodeList nl2 = an.getChildNodes();

        for(int i2=0; i2<nl2.getLength(); i2++) {
            an2 = nl2.item(i2);

            // DEBUG PRINTS
            System.out.println(an2.getNodeName() + ": type (" + an2.getNodeType() + "):");

            if(an2.hasChildNodes())
                System.out.println(an2.getFirstChild().getTextContent());

            if(an2.hasChildNodes())
                System.out.println(an2.getFirstChild().getNodeValue());

            System.out.println(an2.getTextContent());
            System.out.println(an2.getNodeValue());
        }
    }
}

It prints out

tag type (1): 
tag1
tag1
tag1
null
#text type (3):
_blank line_
_blank line_
...

Thanks for the help.
