Capture text in quotes immediately before keyword
Tag : regex , By : user176445

seems to work fine The pattern (?:\"(.*)\" )(?=keyword) matches the first " and then matches the last occurrence where a double quote followed by a space is followed by keyword because the dot also matches a double quote.
Note that in the pattern the non capturing group (?: can be omitted and the " does not have to be escaped.
"([^"]+)"(?= keyword)
const regex = /"([^"]+)"(?= keyword)/g;
const str = `"ignore this" blah "ignore this" blah "capture this" keyword "ignore this" blah`;

while ((m = regex.exec(str)) !== null) {
  if (m.index === regex.lastIndex) {
    regex.lastIndex++;
  }
  console.log(m[1]);
}

wish help you to fix your issue Character negation inside character classes (a.k.a. Negated character classes) are achieved using the ^ char.
So, in your case, replace the ! with ^. Try this:
var str = "hello '' ''world''"

// > hello NULL ''world'' 
console.log(str.replace( /''([^a-z]{1,}'')/g,"NULL$1"));
var str = "hello '' ''world'' ''hello'' '' world"

console.log(str.replace( /(^|[^a-z])''([^a-z]+|$)/g,"$1NULL$2"));
// > "hello NULL ''world'' ''hello'' NULL world"

Regex to capture anchor text in quotes

Any of those help Geez... Literally hours later, I managed to hack together a working DomDocument solution! If there is a cleaner way that maintains accuracy, I welcome anyone to let me know.
Code: (Demo)
$html=<<<HTML
<a href="bla">123 "this" is asd</a>
<a href="bla">this should not be captured</a>
<a href="bla">no quotes in anchor text here</a>
<a href="bla">"445 is in quotes"</a>
<a href="bla">asd "blabla" sometimes</a>
<a href="bla">Je commence à avoir mal à la tête</a>
<a href="bla">something with quotes like “blabla” is bad</a>
HTML;

$dom = new DOMDocument;
$html=mb_convert_encoding($html,'HTML-ENTITIES',"UTF-8");   // for multibyte chars
$dom->loadHTML($html,LIBXML_HTML_NODEFDTD); // remove DOCTYPE, but allow <html><body> tags for stability
foreach($dom->getElementsByTagName('a') as $a){
    if(preg_match('~["“”]~u',$a->nodeValue)){
        $remove[]=$a;  // collect the nodes to remove
    }
} 
foreach($remove as $bad_a){
    $bad_a->parentNode->removeChild($bad_a); // remove targeted nodes
}
$result=mb_convert_encoding($dom->saveHTML(),"UTF-8",'HTML-ENTITIES');  // for multibyte chars
echo preg_replace(['~^<html><body>|</body></html>$~','~\R+~'],['',"\n"],$result);  // mop up <html> and <body> tags, and consecutive newline characters
<a href="bla">this should not be captured</a>
<a href="bla">no quotes in anchor text here</a>
<a href="bla">Je commence à avoir mal à la tête</a>
echo preg_replace('~<a[^>]*>.*?["“”].*?</a>\R?~u','',$html);
