And*_*ers 3 c# xpath webdriver html-agility-pack
这与我之前的问题有关,但似乎我有另一个案例,其中Html Agility Pack无法按预期工作.
这是Html(删除了必需品,删除了敏感信息):
<html>
<select id="one-time-payment-form:vendor-select-supplier">
<option value="1848">Frarma Express</option>
<option value="2119">Maderas Garcia</option>
<option value="1974">Miaris, S.A.</option>
<option value="3063">Ricoh Panama</option>
<option value="3840">UNO EXPRESS</option>
<option value="68">Garrett Blaser Gretsch</option>
<option value="102">Oriel Antonio Grau</option>
</select>
</html>
这是代码:
const string xpath = "//*[contains(@id, 'one-time-payment-form:vendor-select-')]/option[contains(text(), 'UNO EXPRESS')]";
var driver = new FirefoxDriver(new FirefoxProfile()) { Url = "PATH_TO_FILE_CONTAINING_HTML_SHOWN_ABOVE" };
Thread.Sleep(2000);
//Can WebDriver find it?
var e = driver.FindElementByXPath(xpath);
Console.WriteLine(e!=null ? "WebDriver success" : "WebDriver failure");
//Can Html Agility Pack find it?
var source = driver.PageSource;
var htmlDoc = new HtmlDocument { OptionFixNestedTags = true };
HtmlNode.ElementsFlags.Remove("form");
htmlDoc.LoadHtml(source);
var nodes = htmlDoc.DocumentNode.SelectNodes(xpath);
Console.WriteLine(nodes!=null ? "Html Agility Pack success" : "Html Agility Pack failure");
driver.Quit();
当我运行代码时,控制台显示:
WebDriver success
Html Agility Pack failure
很明显,WebDriver找到项目@XPath没有问题//*[contains(@id, 'one-time-payment-form:vendor-select-')]/option[contains(text(), 'UNO EXPRESS')],但Html Agility Pack不能.
有任何想法吗？
这是"按设计".这与OPTION和FORM的想法相同.由于Html Agility Pack的历史原因,某些标签的处理方式不同.当时在HTML 3.2时代,OPTION并不总是关闭,而在HTML 3.2中,它并不是必需的.
尝试添加此:
HtmlNode.ElementsFlags.Remove("option");
