Parsing XML doc

[Mike Dev]

Hi,

I have the following XML file:

<words>
<word>aforementioned</word>
<word>globalisation</word>
<word>internet</word>
<word>extranet</word>
<word>scriptlet</word>
<word>improper</word>
<word>sunset</word>
<word>alternative</word>
<word>degree</word>
<word>grade</word>
</words>

I tried many things, but nothing seems to work (getFirstChild, NextSibling, etc.). Can anyone help, please?

Thanks.
Mike

Welcome to Javaranch Mike.

You may need some dom/sax tutorials first.Some good ones were http://www-128.ibm.com/developerworks/views/xml/libraryview.jsp?type_by=Tutorials , http://www.w3schools.com etc.,

Also if you just want to parse the xml and display it in html form, then try to learn xslt as well. (w3schools got good tutorial on xslt).

OK. The code I've written is the following:

NodeList words = doc.getElementsByTagName("words");
Node n = doc.getDocumentElement();
for (Node child = n.getFirstChild();
child != null;
child = child.getNextSibling())
{
System.out.println(child.getNodeName() +" = "+ child.getNodeValue());
}

However, the getNodeValue() always returns NULL. Is this the normal behavior? Should I use a different method?

Thanks.
Mike

Try this it will work

  Node n = doc.getDocumentElement();
 NodeList nl = n.getChildNodes();
 for(int i=0;i<nl.getLength();i++)
 {
     if (nl.item(i).getNodeType()==Node.ELEMENT_NODE){
         System.out.println(nl.item(i).getNodeName()+" : "+nl.item(i).getFirstChild().getNodeValue());
     }
 } 

The text under each element is a child node and not a sibling also the getNodeValue of an Element returns Null by defination not the text it contains.

IMO DOM is too complex try JDOM it will make life simple.
