Hi,

I am trying to move elements in a list with, by placing the element to move after an element that was found to be the previous element:

list children = parentElem.elements();

This was supposed to be:

int index = children.indexOf(previousElem);

int indexPos = children.indexOf(previousElem);

if (index == -1) {
 children.add(moveElem);
} else {
 children.add(index + 1, moveElem);
}

This works if I have more than one element. If I have only one element in the children list, then the moveElem is placed at the first position in the list.

XML for this problem would look like:

<parent id="abc">
 <child id="def"/>
</parent>

so the child element is set to be the previousElem. The result of the above code is:

<parent id="abc">
 <child id="newElem"/>
 <child id="def"/>
</parent>

thanks for any help,
-Rob
