getElementsByAttribute[Value] has been considered in the past, but never
survived into the spec since there appeared to be adequate (and less
argumentative) alternatives:
In DOM Level 1: Write a tree-walker that searches for those attributes.
There are many existing tree-walkers you can borrow code from.
In DOM Level 2, if Traversal is supported: Implement a NodeFilter which
tests for the presence/value of the attribute and plug that into a
TreeWalker or NodeIterator. Or prescan the document, build a lookup table,
and implement your own retrieval method using that. Or, if you can't
depend on Traversal but can validate the document against a DTD, use
Document's getElementByID method.
In DOM Level 3, if the XPath module is supported: Write a suitable XPath
and evaluate that.
