form submit

RHTMLForms在R高版本中不可用，解决如下

install_github("omegahat/RHTMLForms")

提交表单，http://一定不能省略

u = "http://www.bing.com"
form = getHTMLFormDescription(u)[[1]];form

得到

HTML Form: http://cn.bing.com/search
q:

制作一个form提交的function

bing_search = createFunction(form)

这样bing_search()里面就能提交各式各样的搜索关键字，最后用

getHTMLLinks(bing_search("studio"))

这边得到

中间［13］－［81］是有效链接

如果只是想提取我们需要的链接呢？用xpath，结果更精确，但是也损失了不少信息（怎么处理？）

xpq = "//a/@href[starts-with(.,‘/search?q=rstudio‘)]"
getHTMLLinks(txt,xpQuery = xpq)
