Two problems.
first: the value of an ID attribute cant be a number. It has to be an "XML
Name" and XML Names must start with only with letters, ideograms or
underscore.
so try _33 instead of 33
second:
you have to use a DTD to define what attribute are of type ID!!
the id() function doesnt select all Attributes named 'id' but selects all
elements with attribute of TYPE ID!!!!!
add to your XML at the beginning lines like this:
<!DOCTYPE AAA [
<!ATTLIST BBB id ID #IMPLIED>
]>
this defines attribute id as an ID attribute, so you could also say
<!ATTLIST BBB myident ID #IMPLIED>
and still the id() function knows what to look for.
