Question

I need to tokenize following tag:

{TagName attrib1=”value1” attrib2=”value 3”}.

I would like to write regex to do it, but the trouble is that attribute value can contain space, so I can’t just split with space.

Answer 1

can’t be put more clearly than this:

please explain why you need regexp…

and, you didn’t say anything about your preferred language…

assuming perl:

$str = "{TagName attrib1=\"value1\" attrib2=\"value 3\"}";

if ($str =~ m/{(\w+)\s+(\w+)="(.*?)"\s+(\w+)="(.*?)"/)
{
    print "tagname: $1\n";
    print "attrib: $2\n";
    print "value: $3\n";
    print "attrib: $4\n";
    print "value: $5\n";
}

But again, don’t use regexps for this!!
