Function xmlAddPrevSibling

ThirdParty/libxml2/vtklibxml2/tree.c:3222–3233

* xmlAddPrevSibling: * @next: the target node * @cur: the new node * * Unlinks @cur and inserts it as previous sibling before @next. * * Unlike xmlAddChild this function does not merge text nodes. * * If @cur is an attribute node, it is inserted before attribute * @next. If the attribute list contains an attribute with a name * matching @cur, the old attribute is destroyed. * * See t

 * if arguments are invalid or a memory allocation failed.
