[Javascript] getElementsByTagName not working ???

[flavio at economisa.com.br (Flavio Gomes)]

The problem probably is "when" you are running the script, if you set it 
to be something like

< script >
  (...)
< /script>
< html>
  (...)
< /html>

  The script will run "in execution/loading time" (I don't know a better 
expression)  and when it get to the "getElementsByTagName" line there's 
not any "A" tag loaded in dom/html yet, so it(the script) won't see 
them. Just by putting the script after the html, on triggering it on the 
"onload" event should do.
