Hello dear R-help mailing list. I wish to be able to have htmlParse work well with Hebrew, but it keeps to scramble the Hebrew text in pages I feed into it. For example: # why can't I parse the Hebrew correctly? library(RCurl) library(XML) u = "http://humus101.com/?p=2737" a = getURL(u) a # Here - the hebrew is fine. a2 <- htmlParse(a) a2 # Here it is a mess...

The results of sessionInfo() are attached at the bottom of the message. The thing is, htmlTreeParse appears to work just fine, although it doesn't appear to contain the information I need (the

Hello dear R-help mailing list.

I'm trying to scrape football projections from accuscore.com for the different positions (right now the projections are set to zeros, but that will change). I can get the QB projections, but I can't get the projections for any of the other positions (e.g., RB). How can I get the RB projections?

Hi, beginner to R and was having some problems scraping data from tables in html using the XML package. I have included some code below.

Hi all, Sorry for the rather uninformative subject, but the error I get is not very informative either. When using the XML and RCurl package to retrieve the content of an html page, htmlTreeParse fails, printing out the beginning of the HTML: Error in htmlTreeParse(getURL(url)) : File <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

I'm using the function htmlParse() in the XML package, and I need a little bit help on error handling while parsing an HTML page. So far I can use either the default way: # error = xmlErrorCumulator(), by default library(XML) doc = htmlParse("http://www.public.iastate.edu/~pdixon/stat500/") # the error message is: # htmlParseStartTag: invalid element name or the tryCatch()
