Hi Peter!

Thanks for the answer!

Layout is not important. Your regex works in most cases. But it misses:

static void
xmlLinkDeallocator(xmlListPtr l,
                   xmlLinkPtr lk) {
    (lk->prev)->next = lk->next;
    (lk->next)->prev = lk->prev;
    if(l->linkDeallocator)
        l->linkDeallocator(lk);
    xmlFree(lk);
}

and

static void
xmlLinkDeallocator(xmlListPtr l, xmlLinkPtr lk) {
    (lk->prev)->next = lk->next;
    (lk->next)->prev = lk->prev;
    if(l->linkDeallocator)
        l->linkDeallocator(lk);
    xmlFree(lk);
}

Would it be possible to produce the hack for these two cases?
