在Python中使用RegEx查找以h开头但不包含html标记的单词

Question

I'm trying to find all words beginning with h, but I need to exclude html tags, like within this search. I have the code to find all the words starting with h:

\h\w+

I just don't know how to exclude things within my search specifically an html tag.

Answer 1

Use de exclude character [^]

[^<]h\w+ 

But i think this way may work better for what you want, since it generates a match for every word beginning with h that's not a

 (?!<)h\w+

Even better, do the following match:

 ((?!<)h\w+)

(close attention, there is a blank space just before the first ( )

If the text is:

html teste homem carro agharro hzete h

It will do a full match with " homem" and " hzete", being the first match groups the word you want. "homem","hzete".

I would recomend you a graphical regex validation tool, so you see live the expressions you are writing. A good one is https://regex101.com/

Hope this helps.
