我在尝试使用 HTML Agility 包删除具有特定 ID 的 div 及其子项时遇到困难。我确定我只是缺少一个配置选项,但它是星期五,我正在努力。
简化的 HTML 运行:
<html><head></head><body><div id='wrapper'><div id='functionBar'><div id='search'></div></div></div></body></html>
这是我所得到的。敏捷包抛出的错误表明它找不到 div 结构:
<div id='functionBar'></div>
这是到目前为止的代码(取自 Stackoverflow ....)
HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument();
// There are various options, set as needed
//htmlDoc.OptionFixNestedTags = true;
// filePath is a path to a file containing the html
htmlDoc.LoadHtml(Html);
string output = string.Empty;
// ParseErrors is an ArrayList containing any errors from the Load statement
if (htmlDoc.ParseErrors != null && htmlDoc.ParseErrors.Count > 0)
{
// Handle any parse errors as required
}
else
{
if (htmlDoc.DocumentNode != null)
{
HtmlAgilityPack.HtmlNode bodyNode = htmlDoc.DocumentNode.SelectSingleNode("//body");
if (bodyNode != null)
{
HtmlAgilityPack.HtmlNode functionBarNode = bodyNode.SelectSingleNode ("//div[@id='functionBar']");
bodyNode.RemoveChild(functionBarNode,false);
output = bodyNode.InnerHtml;
}
}
}
