[英]Using javascript and regex to limit replacement and capture within a specific html tag
我正在使用javascript和正則表達式轉換此html代碼：
<html>
<body>
<document>
==id:firstid;
==href:#anchor32145;
==href:#anchor31274;
==href:#anchor98751;
</document>
<document>
==id:secondid;
==href:#anchor62341;
</document>
<document>
==id:thirdid;
==href:#achor52153;
==href:#anchor98421;
</document>
</body>
</html>
變成這種格式：
<html>
<body>
<document>
==id:firstid;
==href: firstid #anchor32145;
==href: firstid #anchor31274;
==href: firstid #anchor98751;
</document>
<document>
==id:secondid;
==href: secondid #anchor62341;
</document>
<document>
==id:thirdid;
==href: thirdid #anchor52153;
==href: thirdid #anchor98421;
</document>
</body>
</html>
如您所見，我正在嘗試將== id：的值分發到同一文檔標簽中的所有= href：。 我對javascript比較陌生，因此非常感謝您能提供幫助。
除了簡單的正則表達式（例如XML解析器）之外，還有其他更明智的方法，
但是既然你要...
const str = ` <html> <body> <document> ==id:firstid; ==href:#anchor32145; ==href:#anchor31274; ==href:#anchor98751; </document> <document> ==id:secondid; ==href:#anchor62341; </document> <document> ==id:thirdid; ==href:#achor52153; ==href:#anchor98421; </document> </body> </html>` const str2 = str.replace(/(?:<document>)[\\s=\\w]*:(\\w*);[a-z0-9;:#\\s=]*/g, (m, m1, m2) => m.replace(/==href:/g, (mm) => ` ${mm} ${m1} `)) console.log(str2)
