R，使用 XML 库和 htmlTreeParse 读取 html 源代码。 我是新手，所以这可能是一个简单的解决方案

Question

I want to be able to read in the source code to extract nodes from the HTML file.

library(XML)
url <- ("https://www.mlb.com/marlins")
html <- htmlTreeParse(url, useInternal=T)

The issue is when I try this i get an error message saying: "XML content does not seem to be XML: '' "

thanks ahead of time

Answer 1

Because it is really not an XML file. To read the source code, try the following script

library(httr)
html <- httr::content(httr::GET("https://www.mlb.com/marlins"))

Answer 2

You can use rvest::read_html to read the source.

data <- rvest::read_html("https://www.mlb.com/marlins")
