如何在这个字符串中获取标签的href属性？

Question

在这个字符串中存在数字li标签.我想获得标签的href属性,例如:

http://bipardeh94.blogfa.com" target="_blank

http://avaejam.blogfa.com" target="_blank

并且......我希望用C#做到这一点.如何做到这一点？我使用此代码,但这不完整.

int indexStartUl = _codeHtml.IndexOf("<ul");
            int indexEndUl = _codeHtml.IndexOf("</ul>");
            _codeHtml = _codeHtml.Substring(indexStartUl, indexEndUl);

请帮忙.

Answer 1

您可以使用Selenium WebDriver以下功能：

IList<IWebElement> lis = driver.FindElements(By.CssSelector(".ull > li"));
foreach (IWebElement li in lis) {
    string href = li.GetAttribute("href");
}

您可以找到所有属于with class子级的WebElementswith标签，并迭代列表并获取 href 属性。liWebElementull
