单击获取元素的外部 HTML

Question

Im making a project for finding xpath, and i need the fastest and easiest way for the user to actually select in a webpage the element he wants the xpath to be found. Selection ideally needs to be made with just a click, which needs to return the value of outerHTML of that element,so I can take it and process against fullHTML of page to find any indicator.

For now, im stuck double-tapping element,pressing inspect element and copying, all manually, which is not good.I know to automate in selenium, but i haven't found a way to automate this process.

Any suggestion,idea or preferably answer would be greatly appreciated! Thanks

You want to see the path to an element when you click on it? Something like this will work:

window.addEventListener("click", (e) => {
  let element = e.target
  let path = []
  while(element.parentElement){
    let i = [...element.parentElement.children].indexOf(element)
    path.unshift(`${element.tagName}:nth-child(${i + 1})`)
    element = element.parentElement
  }
  alert(path.join("/"))
})
