Load a and b in separate DOM Document objects A and B. Extract the value of
the element or attribute in A that you want to look up in B into a variable,
call it "x". Then pass "x" to B's getElementById() method on B. You'll
get back an Element object where it's ID attribute has the value contained
in X.
You will need to declare that the Date elment has an ID attribute called ID
in a DTD or Schema governing B, or getElementById can't work. One nice thing
about HTML/XHTML is that their DOMs understand that "id" is an "ID" attribute
without you having to tell it.
Of course, if there are multiple Date elements with an ID value equal to the value of
x, then undefined and unpleasant things will happen ...but a validating
parser would warn you of that. I don't know if most HTML/XHTML browsers will
warn you or not...
By the way, getElementById() is defined in DOM LEvel 2, so not all DOM
implementations will support it.
