Then use Sigil's regular expression Find and Replace to empty them before running Access Aide.
Something like:
Code:
Find set to use regular expressions with this in the Find field:
<title>[^<]+</title>
And Replace set to:
<title></title>
Then running ReplaceAll should do the trick. But I would make a Checkpoint (or save a copy) just in case it changes something unexpected.
Caveat: I have not tested that but somethin like that should do the trick.
