Webscraping - How to Scrape Out Text Into R As If Copied & Pasted From Webpage?
2 messages · Moser, Gary, Henrique Dallazuanna
Use XPATH query: web.pg <- htmlTreeParse(file=web.pg, ignoreBlanks=TRUE, useInternalNodes = TRUE) # Job title xpathApply(web.pg, "//span[@class='normal']//b", xmlValue)

Greetings,
I am trying to get all of the text from a web page as if I "selected
all" on the page, pasted into a text file, and then read in the text
file with read.csv().
# this is the actual page I'm trying to acquire text from:
web.pg <- readLines("http://www.airweb.org/?page=574")
# then parsed in hopes of an easier structure to work with:
web.pg <- htmlTreeParse(file=web.pg, ignoreBlanks=TRUE)
Now I have a lovely html tree, but don't know the best way to get just
the text components (job descriptions, job titles, etc...) as they
appear on the web site. I'd like to do a little text mining and make a
wordcloud using the text. Can anybody suggest a method to achieve this
result?
Thank you,
