remove duplicate of specific string from the list of string

Question

I want to remove specific string from the list of string. Suppose I have a list like this:

list_ex = ['I', 'went', 'to', 'the', 'big', 'conference', ',', 'I', 'presented', 'myself', 'there', '.', 'After', 'the', '<word>conference</word>', '<word>conference</word>', ',', 'I', 'took', 'a', 'taxi', 'to', 'go', 'to', 'the', '<word>hotel</word>', '<word>hotel</word>', '.']

I want to remove duplicate string for example: "<"word>keyword</word">".

My desired output:

new_list_ex = ['I', 'went', 'to', 'the', 'big', 'conference', ',', 'I', 'presented', 'myself', 'there', '.', 'After', 'the', '<word>conference</word>', ',', 'I', 'took', 'a', 'taxi', 'to', 'go', 'to', 'the', '<word>hotel</word>', '.']

I know how to remove duplicate items from the list but how to remove specific elements in this case by reserving the order?

What you do mean by "with phrase tag."?

That is a simple for loop with the appropriate if condition:

new_list_ex = []
for item in list_ex:
    if item.startswith('<word>') and item in new_list_ex:
        continue
    new_list_ex.append(item)
