Regex: Delete duplicate double quote (apostrophe) on a html tag (from string)

Question

I have this html tag (from string):

<meta name="description" content="I love my mother" but I love my sister" more than I can say"/>

As you can see, I have 4 double quote (apostrophe) in the content section. Should be only 2 double quote: one at the beginning content=" and one at the end "/>

I must find all tags that contains other double quote except those 2 in the content section, and delete them:

Output should be:

<meta name="description" content="I love my mother but I love my sister more than I can say"/>

I made a Regex, but not too good. Maybe you can help me:

FIND: (?-s)(<meta name="description" content=")(*?\K.*"(?s))"/>

REPLACE BY: \1\2

Answer 1

Here is a way to go:

• Ctrl+H
• Find what: (?:<meta name="description" content="|\G(?!^))[^"]*\K"(?=.*?"/>)
• Replace with: LEAVE EMPTY
• CHECK Wrap around
• CHECK Regular expression
• UNCHECK . matches newline
• Replace all

Explanation:

(?:             # non capture group
  <meta name="description" content="      # literally
 |               # OR
  \G(?!^)         # restart from last match position (not at the beginning of a line)
)               # end group
[^"]*           # 0 or more non quote
\K              # forget all we have seen until this position
"               # a double quote
(?=.*?"/>)      # positive lookahead, make sure we have "/>  somewhere after
