I have a xml document and in that document, I could have a mixture of elements and attributes.

Is there Java code available out there to drop empty elements and attributes? I don’t want to have to go through each elements and/or attributes to find out if their value is null or empty then dropping it.

There must be a better way.

Really roughly, off the top of my head and not compiled (let alone tested):

 
public void dropEmptyValues (IData aDoc)
{
IDataCursor vCsr = aDoc.getCursor();
boolean vOk = vCsr.first();
while (vOk)
{
Object vValue = vCsr.getValue();
if (vValue == null)
vOk = vCsr.delete(); // moves to next value if there is one
else
if (vValue instanceof String && ((String)vValue).equals(""))
vOk = vCsr.delete();
else
{
// recurse through child docs
// beware of reference loops (not checked here)
if (vValue instanceof IData)
dropEmptyValues((IData)vValue);
else
if (vValue instanceof IData[])
{
IData vDocs[] = (IData[])vValue;
for (int i = 0; i < vDocs.length; i++)
dropEmptyValues(vDocs[i]);
}
vOk = vCsr.next();
}
}
vCsr.destroy();
}

HTH!
