I know of no xFolk Parser in PHP.  I have however written xFolk  
parsers in javascript.  I have discussion of those here:


and here:


I have also linked between tagging services as I describe here:


and here:


In a nutshell, I think there are really three generic parser  
strategies to pursue.  One is to treat your html document as xml and  
apply tools like XPath and XSLT.  The second is to somehow create a  
DOM tree and then walk it.  Both of these strategies are easily  
applied in browsers which essentially go through the pain of parsing  
the html file for you and give you a data structure to work with.   
XPath and XSLT are most easily applied to html documents in firefox  
while DOM walking applies to both firefox and ie.  The third parser  
strategy is to really go low level and scan the document like it was  
a text file.

As for creating a cross-service tag aggregator, I have both just used  
the RSS feeds and have used client side javascript processing of html  

If you have more specific questions, I'll be happy to take a crack.
