I’ve been trying to create a RegEx for a string for almost a day

  • 0

I’ve been trying to create a RegEx for a string for almost a day and still haven’t made it work, can anyone help?

string example (double quotes are options, and can also be single quotes):
    "234"? "<img src=\"http://abc.com/a.jpg\" onclick=\"alert(\"\"working with 'quotes'?\"\");\" />"

and the following groups should be extracted:
    234
    <img src="http://abc.com/a.jpg" onclick="alert(""working with 'quotes'?"");" />

hope this is clear, anyone help pls!!

    I’m not sure about the efficiency of this regex, but here is one that matched your string.

    Rules

    1. Quotes around number are optional, and can be single-quotes.
    2. Quotes around html are optional, and can be single-quotes.
    3. Space(s) after question mark can be 0 or many.

    Input

    "234"? "<img src=\"http://abc.com/a.jpg\" onclick=\"alert(\"\"working with 'quotes'?\"\");\" />"

    Regex

    ^['"]?(?<number>\d+)['"]?\?\s*['"]?(?<html>\<.*\>)['"]?$

    Output Groups

    number: 234
html: <img src=\"http://abc.com/a.jpg\" onclick=\"alert(\"\"working with 'quotes'?\"\");\" />
