I seem to be getting stuck trying to define my variable to print based on your help. I'm using:

my $abstr = $dom1->find('div.abstract-content > p')->each;

but gettting an error.

`each` returns a list but you are calling it in scalar context. Use list context as marto did and you will be fine. See also: Context tutorial. but gettting an error. Don't keep it a secret. Always provide the full text of the error message.	[reply] [d/l]

Is there more than one abstract per html page? My example uses `foreach` to print the text for each match we find, using the selector which matches your requirement. See find. If you know for sure that each page has one abstract you could do something like `my $abstract = $dom->at('div.abstract-content > p')->text;`. If you post the error you have maybe I can provide more help, see also How do I post a question effectively?. In your example `$abstr` will contain the number of matches.	[reply] [d/l] [select]
