    How can I modify the tree during iteration?

    +

    lxml's iterators need to hold on to an element in the tree in order to remember +their current position. Therefore, tree modifications between two calls into the +iterator can lead to surprising results if such an element is deleted or moved +around, for example.

    +

    If your code risks modifying elements that the iterator might still need, and +you know that the number of elements returned by the iterator is small, then just +read them all into a list (or use .findall()), and iterate over that list.

    +

    If the number of elements can be larger and you really want to process the tree +incrementally, you can often use a read-ahead generator to make the iterator +advance beyond the critical point before touching the tree structure.

    +

    For example:

    +
    from itertools import islice
+from collections import deque
+
+def readahead(iterator, count=1):
+    iterator = iter(iterator)  # allow iterables as well
+    elements = deque(islice(iterator, 0, count))
+    for element in iterator:
+        elements.append(element)
+        yield elements.popleft()
+    yield from elements
+
+for element in readahead(root.iterfind("path/to/children")):
+    element.getparent().remove(element)
+
