Using XML::XSH2 , I had to fix the script after downloading the XML: I hadn't had the namespace there, and I tried normalize-space instead of substitution which didn't work correctly. 
open 1201438.xml ;
register-namespace xh http://www.w3.org/1999/xhtml ;
my $first = 1 ;
for //xh:div[@class='data'] {
    if not($first) echo :n ', ' ;
    $first = 0;
    echo :s :n @id '=' xsh:subst(., '\W', '', 'g') ;
}
echo ;
