Hello EE,

I have in my vb.net project HtmlUtilityPack import.

Im trying to find a Div and the result I insert in a HtmlNodeCollection like this :

        Dim nodes As HtmlNodeCollection = doc.DocumentNode.SelectNodes("//div[@id='myID']")

Open in new window


but inside this DIV there are many <a href='www.something.com' title='hello'></a>

I want all the title attribute of al of them. but only in that specific div..

im not sure where to go with this... should be soemthing like :

Dim list as new List(of string)
For Each node As HtmlNode In nodes
  list.add(node.SelectNode("a").GetAttribute('title"))
Next

can you help ?
thanks

Do you mean HTML Agility Pack? If so, you can set up your XPath to select that attribute for you.

e.g.

Dim nodes As HtmlNodeCollection = doc.DocumentNode.SelectNodes("//div[@id='myID']//a/@title")

Open in new window


Then you could just iterate over that result set:

Dim list as new List(of string)

For Each node As HtmlNode In nodes
  list.add(node.InnerText)
Next

Open in new window

yes sorry agility.

but it cant be done on 2 lines? i need to do it on doc.DocumentNode?

i cannot do it on the nodes variable to reach @a?

because otherwise i always need to re-iterate on doc variable and sometimes there is tons of source code lines, but still maybe its fast also.. i dont know

I'm probably not understanding what you are asking, but if you would like to stick with the logic you currently have, then it should be along the lines of:

For Each node As HtmlNode In nodes
  list.add(node.SelectSingleNode("a").Attributes("title").Value)
Next

Open in new window
