Okay, it didn't even slightly work though. Also I changed the data to make it easier for you guys to help.

foreach my $info ($root->children('data')){
    my $INTEREST2 = $drug->first_child_text('groups/group');
    print "$INTEREST2";
    print "\n";
}

I have no idea how to capture INTEREST1 as it is within the tag. What I've written here didn't work as groups/group is not valid.

There are several ways to get the data. `first_child` only goes down 1 step in the tree. To get the text, you would need `$drug->first_child('groups')->field( 'group')`, or `$drug->next_elt( 'groups')->text` or `$drug->findvalue( 'groups/group')`. INTEREST1 is an attribute, so you would get it with `$drug->att( 'type')`. There is probably a problem though either with your simplified data or with the code. You have te tags in your example as `data1` and `data2`. If this is really the case, then you won't access them with `$root->children('data')`, since the tags are NOT `data`. So either the tags are `data`, or you have to get them using `$root->children`.	[reply] [d/l] [select]

Thank you, that is very helpful. And yes the tags data1 data2 should just be data, that was my mistake :)	[reply]

Well, you should be using handlers or roots, not the DOM-ish interface See Re^3: parse xml and store data in array of hashesh, Parsing HTML / Re^4: Parsing HTML, A regex question , NASA's Astronomy Picture of the Day / Re: NASA's Astronomy Picture of the Day, Re: Search and replace query ( twig and xsh (XML::LibXML/xpath )	[reply]
