R help - Mar 2012 - trouble for parsing HTML files

Hi all,

Using the XML package, I'm not able to parse some html webpages. Here  
is my code and the error message:

library("XML")
url <-
"http://www.huffingtonpost.com/social/GraniteSkyline?action=fans"
doc <- htmlParse(url)

Error: Namespace prefix ??? of attribute (null) is not defined

I've searched a lot on the Internet, but it's really difficult to find  
something useful for R.

Thanks for your help!

Julien

What versions of R and XML are you using? The code you provided works
fine here (R 2.14.1 x86_64 and XML 3.9-4 on Fedora 16). sessionInfo()
will help us.

BTW, see ?RSiteSearch to search for R content on the Web.


Cheers

Sorry for the multiple messages.
------

I use mac OS 10.5.8 with this version of R:

R version 2.14.1 (2011-12-22)
Platform: i386-apple-darwin9.8.0/i386 (32-bit)

I've tried the command "RSiteSearch", but with no result.

BTW, I recall that the code I've posted works for some websites.
