vb.net dom elements #15

Closed bettesn closed 5 years ago

bettesn commented 5 years ago

Not sure if this is the correct place to ask questions but I can't find any other support forums.

In vb.net the engine retrieves a page ok - I can display it - a google rearch result as it happens. However

Dim LClasses As ITokenList = _engine.Document.ClassList returns a 0 length list (even though I can see classes in the page source) and Dim LNodes As List(Of Node) = _engine.Document.ChildNodes returns only 2 nodes: html and head - even though there are of course dozens of other nodes.

Is vb.net supported? Am I doing something stupid?

Thanks

1) Document.ClassList should be empty. In real browsers this property is undefined. 2) ChildNodes returns children, not descendants. Most often there are only two such nodes: DocType and html. 3) I can not guarantee that vb.net will work. But I see no reason why this should not be.

Ok I now understand that I need a recursive function to find all the elements or search for a particular one. Thanks.
