how to exclude some reg pattern

I want to write a regular expression to search out all "http" string and replace it with "https", I use following Reg expression: 

\bhttp\b

but some results are not what I want, for example: 

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

so how can I exclude this? I want to use notepad++ to do this.

Ultimately if the data is not structured, and you have to string filter, then you need to assess the whole dataset, and decide if this is to be done as a once-off, or if you need a system to do frequently perform the same type of operation, on similar documents, or very different documents, etc..

If it is only the meta line example you want to exclude:

  • You can try \bhttp[^-]\b

If all relevant instances of http are in a certain format, i.e. href="http:

  • Then you could just be more specific with the context. i.e. \b(?<=href=")http\b

The latter example will match using href=" but not include it in the replace operation
