How to get first only first 2 digits using Regular expression

Question

I am using JMeter and trying to write a Regular expression (regex) that can return the two digit class ID from some HTML option elements.

<option value="53">1ABC Class</option>
<option value="52">2XYZ Class</option>
<option value="69" selected="selected">001 Class</option>

using following regex..

value="..">1ABC Class<

returns

value="53">1ABC Class<

In the example given, the only return values I want are 53, 52 and 69.

I am looking for a regex that will work with all of above given options.

What is the regex flavor/programming language/tool? Is it for JMeter? — Wiktor Stribiżew, Nov 29 '16 at 12:11
Don't use regex to parse HTML, XML, or other mark-up languages. Parsers are much more reliable than any regex that you may construct. — Sergey Kalinichenko, Nov 29 '16 at 12:12
If you can use the Xpath Extractor (and I think you can), the xpath will be `//option[text() = '1ABC Class']/@value` to get `53`, or `//option/@value` to get the `values` of `option` nodes. — Wiktor Stribiżew, Nov 29 '16 at 12:15
Yes, wiktor it is for JMeter and I am checking it with https://regex101.com/ — TestingWithArif, Nov 29 '16 at 12:26

Never use regular expressions to parse HTML. Each time you use regular expressions to parse HTML somewhere somehow a kitten dies.

Go for CSS/JQuery Extractor

Go for XPath Extractor

But do me a favour, don't use regular expressions for HTML.

Thanks. Even though moustafa solution worked but I went with xpath extractor as suggested by wiktor. Will try CSS extractor later as well. – TestingWithArif Nov 29 '16 at 18:17

Try this:

value="(\d+)".*?>1ABC Class<

This will give the result in the brackets as the needed value only, plus it would match any tag.

Not Regex solution for c# or vb.net

var doc = XDocument.Parse(yourXmltext);
var options = doc.Root.Descendants("option");

foreach(var option in options)
{
    var value = option.Attribute("value").Value;
    var className = option.Value;
}

LINQ to Xml makes code little bid more readable

If it is for JMeter, this C# code will be of no use. – Wiktor Stribiżew Nov 29 '16 at 12:12
