需要HTML Agility Pack的帮助!
基本上我想用HTML的正文节点获取纯文本.到目前为止,我已经在vb.net中尝试了这个并且它无法返回innertext意味着没有看到任何变化,至少从我能看到的内容.
Dim htmldoc As HtmlDocument = New HtmlDocument
htmldoc.LoadHtml(html)
Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")
If Not htmldoc Is Nothing Then
For Each node In paragraph
node.ParentNode.RemoveChild(node, True)
Next
End If
Return htmldoc.DocumentNode.WriteContentTo
我试过这个:
Return htmldoc.DocumentNode.InnerText
但还是没有运气!
任何建议???
我想使用HtmlAgilityPack将遍历documnet中的所有节点
foreach (HtmlNode node in myhtml.DocumentNode.SelectNodes("//@"))
做？
我正在使用HtmlAgilityPack.是否有一行代码可以获取html的所有内部文本,例如,删除所有html标签和脚本？
如何div使用CSQuery通过ID 从标记中检索值？
例如,
<h3>
<div id='type'>
Room 1
</div>
<div id='price'>
145
</div>
</h3>
在这种情况下,我想把内容type和内容price.
