how to append an element after another element on same depth
hello,
this is more a DOM-question than a batik question.
how can i attach a node (basically a <g>) right after another node (maybe a
g, path, rect, circle, ...).
it should be the next sibling then, so that as an svg it shows up above it.
i tried it with
element.getNextSibling().getNextSibling().appendChild(importedElement);
the first sibling is the text-node and the next seems to be the
closing-node. so appending right after that should do the trick.
sometimes this works, but sometimes it results in NPE, since the element
does not always seem to have two siblings.
thanks for any help on this!

The code looks correct to me,
are you sure that importedNode comes really from the same
document of element? (check that getOwnerDocument() is the
same)
To be honest, I don't remember if insertBefore accepts a null
as the first argument to the call (the case in which element has
no nextSibling), this might generate errors.
Another corner case could be that element and importedNode are
the same Java Object...
Anyone on the list can shed light?
Luca.

Luca, needs to check the docs (like I need to do every time ;),
'importedNode' and 'element.getNextSibling()' are in the wrong order.
The code should be:
Node parentNode = element.getParentNode();
parentNode.insertBefore(importedNode, element.getNextSibling());

thank you very much for your answer, Luca.
unfortunately that gives me this dom exception:
org.w3c.dom.DOMException: The child node (type: 1, name: g) is missing.

Hi emzic,
What you want to do is, probably:
Node parentNode = element.getParentNode();
parentNode.insertBefore(element.getNextSibling(),importedNode)
Cheers,
Luca.
