How to create the following XML tag through DOM in Java

<tableCategory>
        <item app_name="APPNAME1i" desc="BDESC1" lang="1ODDD"/>
</tableCategory>

In the above xml tag, I want to add one more item as follows-

<item app_name="APPNAME2" de开发者_高级运维sc="DESC2" lang="2ODDD"/>

So finally the XML tag will look like-

<tableCategory>
            <item app_name="APPNAME1i" desc="BDESC1" lang="1ODDD"/>
                <item app_name="APPNAME2" desc="DESC2" lang="2ODDD"/>
 </tableCategory>

I am getting the tag -

Element paletteElement = (Element) doc.getElementsByTagName("tableCategory").item(0); //tag

But not getting the clue after that.

Assuming you are using javax.xml.parsers, element.appendChild() will do.

In case, you are looking for how to create a new Element, below is an example snippet

Element newElem = doc.createElement("item");
newElem.setAttribute(...);
...
...
elem.addChild(newElem);

Look at the Element.addContent() method
