Line 229:
The script goes through the list multiple times, until it no longer finds dead end redlinks. This is because when it removes a redlinked end node, that may cause its redlinked parent to become a dead end node (such as when it has no other children). Multiple iterations catch these. So the entire branch starting with Redlink 10 will be deleted.
'''Here is the problem I've run into:''' the script currently and erroneously deletes the Redlink 3 list item. Because $1\* or $1\\* do not seem to be identifying the Redlink 4 list item as having more asterisks in the wikisource than the Redlink 3 list item. I do not know why. What should happen is that Redlink 3 would be retained because of Redlink 4, and after Redlink 4 is removed, then Redlink 3 is checked again and is kept by virtue of having Psychology as a child. But, when Redlink 3 is deleted in error, it makes Psychology a child of Geology, thus ruining the tree structure.
All this processing is to be done in the editor, so that the redlinked entries are actually removed from the article.
