Choose specific match result group

Randy Role · August 21, 2012

Hey,

Regex is usually denotated to match groups as $n, where n is the capture group.

Does anybody know if there's a way to choose a group number with ubot? $1, $2..

Thanks

This website is the perfect place to try different regex to see is which works best: http://rubular.com/

If you are unsure, try the website for tips and ways to test your regex.

Should be of substantial help.

I use rubular.com all the time, unfortunately I couldn't find a solution how to choose a specific match group.

I know in Java they can choose which group to pick out of the matching groups (first, second...).

Here's an example of what I'm trying to achive: http://rubular.com/r/BB7KMMQxyO

There are two match groups. I'm trying to be able to always pick the first (or second) group.

This will be very usefull for data scrapping.

You can for example do match groups in a javascript block, but I dont know how to return values from it.

Any ideas?

Hi,

You could load the regex matches in to a ubot list. Then select from the ubot list.

Sample code:

regexpage()
regextext()
define regexpage {
load html("<html>
<head></head>
<body>
<div id=data1>!cba123!</div>
<div id=data2>!abc123!</div>
<div id=data3>!123abcabc!</div>
<div id=data4>!321cbacba!</div>
</body>
</html>")
set(#loadpagescrapedata, $scrape attribute(<outerhtml=w"<div id=\"data*\">*</div>">, "innertext"), "Global")
set(#loadpagedata, $find regular expression(#loadpagescrapedata, "!((?:abc|123)+)!"), "Global")
clear list(%regexpagematches)
add list to list(%regexpagematches, $list from text(#loadpagedata, $new line), "Delete", "Global")
set list position(%regexpagematches, 0)
loop($list total(%regexpagematches)) {
 if($comparison($list position(%regexpagematches), "<", $list total(%regexpagematches))) {
	 then {
		 if($contains($next list item(%regexpagematches), "3abc")) {
			 then {
				 set(#pagedatamatch, $list item(%regexpagematches, $subtract($list position(%regexpagematches), 1)), "Global")
			 }
			 else {
			 }
		 }
	 }
	 else {
	 }
 }
}
}
define regextext {
set(#pagedata, "!321cba!
!abc123!
!123abcabc!
!321cbacba!", "Global")
set(#extractdata, $find regular expression(#pagedata, "!((?:abc|123)+)!"), "Global")
clear list(%regexmatches)
add list to list(%regexmatches, $list from text(#extractdata, $new line), "Delete", "Global")
set list position(%regexmatches, 0)
loop($list total(%regexmatches)) {
 if($comparison($list position(%regexmatches), "<", $list total(%regexmatches))) {
	 then {
		 if($contains($next list item(%regexmatches), "c12")) {
			 then {
				 set(#datamatch, $list item(%regexmatches, $subtract($list position(%regexmatches), 1)), "Global")
			 }
			 else {
			 }
		 }
	 }
	 else {
	 }
 }
}
}
