Returns the first WebDAV sibling of the given element that has the
given name, or <code>null</code> if no such sibling exists. If
firstToLast is true, only the sibling's next children are searched,
otherwise, only the siblings previous children are searched. The
element must not be <code>null</code> and must be a WebDAV element.
The name of the sibling to search for must not be <code>null</code>.

@param element the element whose sibling is being searched for
@param name the name of the sibling being search for
@param firstToLast a boolean specifying the direction to search for
the sibling among the element's siblings
@return            the sibling with the given name, or
<code>null</code>

Returns the first WebDAV sibling of the given element that has the given name or <code > null< / code > if no such sibling exists . If firstToLast is true only the sibling s next children are searched otherwise only the siblings previous children are searched . The element must not be <code > null< / code > and must be a WebDAV element . The name of the sibling to search for must not be <code > null< / code > .
