Extracting information from web pages

Are there any tools which I could use to extract link information 
from web pages in the form of RDF?

I have a large personal wiki with over 1000 pages of information 
which I have built up over a long period.  The pages are produced 
as HTML "on the fly" when needed.

I would like to update the tools to use an RDF aware wiki system, 
but would need to extract the information from the existing wiki.

Any suggestions would be appreciated.

Thanks
