推荐答案
试用HTMLagilityPACK
Try HTMLagilityPACK
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.Load(filePath);
// Use: htmlDoc.LoadHtml(xmlString); to load from a string (was htmlDoc.LoadXML(xmlString)
// 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)
{
// Do something with bodyNode
}
}
}
使用ASP.NET中的HtmlAgilityPack（HAP）刮取HTML DOM元素 [ ^ ]
