tested it, works for me. The construct [^_]+ is used in the regular expression to capture anything NOT containing an underscore, which is necessary to get to the second &quot;element&quot; containing your &quot;03&quot; (which is caught the same way).<br />

Hi Folks,<br />
<br />
I have a javascript variable which has a value of &quot;ab_03_01_0010.htm&quot;<br />
<br />
I need to extract 03 out of the string and put it in another var. The naming convention will be the same always.<br />
<br />
var stringVal = &quot;ab_03_01_0010.htm&quot; ;<br />
<br />
I need the solution so that I get<br />
var subStringVal = &quot;03&quot;<br />
<br />
Thanks<br />
