I realized that the string.replace function doesn't actually do
anything to the string, so I have to assign b.replace to a variable
and write that back, something like 'var c = b.replace...', then
document.body.innerHTML = c. That, though, writes the string back
literally into the page, even when I replace < with <, etc.
So, I'm going to do a document.evaluate to get all the text nodes I
want, and then process them, replacing any citations to US reports
with a document.createElement('a').
Sorry to be so thick today!
