Rvest to manipulate and extract value from HTML

Question

Using RI have getBrandlist in html as

 <div>\n  <span class="txt edittext">BrandName1 </span>\n  <span 
 class="cnt" data-val="116">(42)</span>\n</div>
 <div>\n  <span class="txt edittext">BrandName2 </span>\n  <span 
 class="cnt" data-val="116">(62)</span>\n</div> 
 ......

Now I have the number 62. I wish to extract BrandName2 that corresponds to this value. I tried using html_node(getBrandlist, css = '.cnt') %>% html_attr() How do I go about this. Any help will be greatly appreciated.

You can do

library(rvest)
doc <- read_html('<div>\n  <span class="txt edittext">BrandName1 </span>\n  <span 
 class="cnt" data-val="116">(42)</span>\n</div>
 <div>\n  <span class="txt edittext">BrandName2 </span>\n  <span 
 class="cnt" data-val="116">(62)</span>\n</div> ')
html_node(doc, xpath = "//span[text()='(62)']/preceding-sibling::span") %>% html_text
# [1] "BrandName2 "
