Dear colleagues,

RMySQL: Slower parsing over time with htmlTreeParse()
Dear List,
has anyone of you experienced a significant increase in the time it takes to
parse an URL via "htmlTreeParse()" when this function is called repeatedly
every minute over a couple of hours?
Initially, a single parse takes about 0.5 seconds on my machine (Quad Core,
2.67 GHz, 8 MB RAM, Windows 7 64 Bit), . After some time, this can go up to
15 seconds or more.

XML htmlTreeParse fails with no obvious error
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"

How to suppress errors from htmlTreeParse() function in XML package?
Dear R-help,
The following code downloads an html document into variable 'doc' and
then stores an internal representation into variable 'html.tree'. Even
if the html code is malformed, this still works which is fantastic.
However, as in the example below, i do get some ouput from R in the
console which i would like to suppress somehow, so i can keep my
window a bit cleaner.
