How are you looping through the nodes? Are you sure you are not using
the unlinked node to determine the next node to process?
// Code like this is wrong:
xmlNodePtr node = first;
while (node != null) {
if (some condition) {
xmlUnlinkNode(node);
}
node = node->next; // ERROR! node is already unlinked and next may
not be valid
}
What you need to do is to save the "next" node _before_ unlink:
xmlNodePtr node = first;
while (node != null) {
xmlNodePtr nextNode = node->next;
if (some condition) {
xmlUnlinkNode(node);
}
node = nextNode;
}
