使用c#和XPath从输入中使用pupperteer-sharp获取InnertText

Question

如何使用XPath从<input>获得innerText ?

我有这个工作，但与CSS，但它不适合我的XPath

IElementHandle ha = await page.QuerySelectorAsync(xpath);
IJSHandle ith = await ha.GetPropertyAsync("value");
string val = ith.RemoteObject.Value.ToString();

以下内容适合我:

using PuppeteerSharp;
using var browserFetcher = new BrowserFetcher();
await browserFetcher.DownloadAsync();
await using var browser = await Puppeteer.LaunchAsync(new LaunchOptions { Headless = true });
using (var page = await browser.NewPageAsync())
{
await page.GoToAsync("http://www.google.de/");
var input = (await page.XPathAsync("/html/body/div[1]/div[3]/form/div[1]/div[1]/div[4]/center/input[1]"))[0];
var ith = await input.GetPropertyAsync("value");
var val = ith.RemoteObject.Value.ToString();
Console.Write(val);
}
