rvest
...n problemas, escribo el nuevo y hay algo que me olvide.
Básicamente desde el navegador de internet selecciono el xpath, copio y pego este en R, pero me sale el siguiente error.
> text <- Pagina.R %>%
+ html_nodes(xpath='//*[@id="content"]/p')%>%
+ html_text()
> text
character(0)
Miré mi código viejo junto con el sitio que funciona, pero le hice una modificación para que ande (algo en el xpath) pero hoy no recuerdo la parte técnica.
Básicamente hay una lista y recorro los elementos de esta (como si fuese una tabla, pero no lo es), tomand...

Instrucciones uso rvest
Hola buenos días:
Os remito una duda (en un documento word para su mejor expresión) sobre el uso de la libreria rvest. Mi problema es que como no soy informatico me pierdo un poco, he visto los ejemplos que hay colgados y los he seguido, pero el tema es que quiero acceder a los datos del INE, que en ocasiones estan un poco escondidos con menu de selecciones y no se como hacerlo con rvest para

truncating html text
I''ve got a fairly basic problem here that I''m hoping there is an easy
solution for.
I have a chunk of html code that I want to truncate to a given length...
say 20 characters or so.
If I use the ''truncate'' helper function I end up with unbalanced tags.
For example.
<a href=www.someplace.com>A really long string of words</a>
becomes

Web scraping different levels of a website
...l <- ("http://catalog.ihsn.org/index.php/catalog#_r=&collection=&country=&dtype=&from=1890&page=1&ps=100&sid=&sk=&sort_by=nation&sort_order=&to=2017&topic=&view=s&vk=")
read_html(url) %>%
html_nodes(".title a") %>%
html_text() %>%
as.data.frame()
}) %>% do.call(rbind, .)
I have repeated the same code in order to get all the data I was interested in and it seems to work perfectly, although is of course a little slow due to the Sys.sleep() thing.
My issue has raised once I have tried to scrape the single projects...
