parse an HTML page with verbose error message (using XML)
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() approach:
# error = NULL, errors to be caught by tryCatch()
tryCatch({
doc = htmlParse("http://ww...

XML: Slower parsing over time with htmlTreeParse()
...4 Bit), . After some time, this can go up to
15 seconds or more.
I''ve tried garbage collect, "catalogClearTable()" (though I don''t think that
has anything to do with the issue) and lately wondered if it maybe had to do
with the accumulation of errors over time ("xmlErrorCumulator()"). Are
parsing errors cumulated globally in the workspace over distinct calls to
this function? If so, is there a way to "clean the buffer"?
I would greatly appreciate if anyone had an idea about how to keep
request/parsing time fairly constant at the initial low level of 0...

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.
