我怀疑最初的网页只显示前10个结果，然后剩下的结果会随着用户向下滚动而动态加载，所以使用rvest很难做到这一点。下面是使用RSelenium的方法：
我还将html节点更改为h1。您找到的节点对我不起作用，但h1仍然从该页面中提取鞋子名称。

# define url ---------------------------------------------------------
url <- "https://www.aliexpress.com/w/wholesale-running-shoes.html?SearchText=running+shoes&catId=0&g=n&initiative_id=SB_20230318171033&sortType=total_tranpro_desc&spm=a2g0o.home.1000002.0&trafficChannel=main"

# start RSelenium ------------------------------------------------------------

rD <- rsDriver(browser="firefox", port=4548L, chromever = NULL)
remDr <- rD[["client"]]

# Navigate to webpage -----------------------------------------------------
remDr$navigate(url)

# scroll to bottom of the page to load all the results
webElem <- remDr$findElement("css", "body")
webElem$sendKeysToElement(list(key = "end"))

# pull page html
html <- remDr$getPageSource()[[1]]

# Use Rvest to read the webpage
AlPage <-html %>% read_html()

# scan the webpage for the h1 node and pull the text associated with that node

alproduct_name <- AlPage %>% 
                  html_nodes("h1") %>% 
                  html_text2()

alproduct_name

46个结果正确吗？
