Regex for single match of the xml tag's content

Question

I have a string:

<tag1 qwer=123>Hello</tag1>

And I want a regex that will have a single match for its inner content:

Hello

Using the following code:

string s = "<tag1>Hello</tag1>";
smatch sm;
regex re("<tag1>([\\s\\S]*?)</tag1>");
regex_match(s, sm, re);

I get one match and one its submatch:

<tag1>Hello</tag1>
Hello

What regex should I use to get simply one match:

Hello

Thanks!

You should learn the difference between match and capture group — Thomas Ayoub, Mar 24 '17 at 14:16
There is no way to do that with an ECMAScript regex because it does not support lookbehinds. Besides, it is no big deal to access the capturing group value, you already know how to do it. — Wiktor Stribiżew, Mar 24 '17 at 14:16
Parsing XML with regex is the worst idea ever. Use a library like PugiXML. — The Quantum Physicist, Mar 24 '17 at 14:28
Use an XML parser. See [What XML parser should I use in C++?](http://stackoverflow.com/a/9387612/147845). — You, Mar 24 '17 at 15:18

This works for valid single-line XML tags:

regex re("[<][^>]+[>]([^<]+)[<]\/[^>]+[>]");
