Presented is a string consisting of an XML string below:
var xmlString = "<str>rvrv</str>rvrv<q1>vrvv</q1>vrvrv<q2>rtvrvr</q2>";
I am seeking assistance on how to eliminate text that lies outside the tags (text not enclosed by any tag) using regular expressions. Can anyone help me with this?
If you are faced with the task of extracting text that is not enclosed within an HTML element, provided that the code is well-formed and does not contain incorrect strings like
var str= "<str>lorem <b>ipsum</str>";
You can achieve this using a regular expression such as the one below:
var str= "<str>rvrv</str>rvrv<q1>vrvv</q1>vrvrv<q2>rtvrvr</q2>",
elements = str.match(/<(.+?)>[^<]+<\/\1>/gi);
console.log(elements.join(''));
The output of this would be:
<str>rvrv</str><q1>vrvv</q1><q2>rtvrvr</q2>
Please note that in order to detect closing tags, a backreference was used (refer to )
