c# - 传递 HTML 页面字符串并使用 HtmlAgilityPack 进行抓取

Question

为什么会出现此错误？

"Illegal characters in path" at htmlDoc.Load(pageSource)

pageSource 是 HTML 页面的字符串变量。我需要将页面源作为字符串传递，而不是作为文件而不是 URL。我该怎么做？

Dim ids As New List(Of String)()
Dim pageSource = getHtml(url)

Dim htmlDoc As HtmlDocument = New HtmlDocument()

htmlDoc.OptionFixNestedTags = True


htmlDoc.Load(pageSource)


Dim s As HtmlNodeCollection = htmlDoc.DocumentNode.SelectNodes("//div/@id")

For Each div As HtmlNode In s
    ids.Add(div.Id)
Next

Answer 1

使用LoadHtml代替Load:

htmlDoc.LoadHtml(pageSource)
