如何匹配的網址不引號內

Question

這是類似於此regex match keywords that are not in quotes但在JavaScript中，我正則表達式是這樣的：

/(https?:((?!&[^;]+;)[^\s:"'<)])+)/ 

，需要通過標籤來代替所有網址，但不是當他們是引號內，我怎樣才能做到這一點？

您可以使用與所提議主題中提議的解決方案相同的解決方案。在JavaScript

代碼段：

var text = 'Hello this text is an <tagToReplace> example. bla bla bla "this text is inside <tagNotToReplace> a string" "random string" more text bla bla bla "foo"'; 

var patt1=/<[^>]*>(?=[^"]*(?:"[^"]*"[^"]*)*$)/g; 
text.match(patt1); 
// output: ["<tagToReplace>"] 

text.replace(patt1, '<newTag>'); 
// output: "Hello this text is an <newTag> example. bla bla bla "this text is inside <tagNotToReplace> a string" "random string" more text bla bla bla "foo"" 

圖案的說明是一樣的提議F.J.：

text   # match the literal characters 'text' 
(?=    # start lookahead 
    [^"]*   # match any number of non-quote characters 
    (?:   # start non-capturing group, repeated zero or more times 
     "[^"]*"  # one quoted portion of text 
     [^"]*   # any number of non-quote characters 
    )*    # end non-capturing group 
    $    # match end of the string 
)    # end lookahead
