[Help] GetElementById , Simple question
Can you elaborate I'm not sure I get your question, I think if you want to get the ElementByID use
Code:
Webbrowser1.Document.GetElementbyID ("?")
Lol NO, I want to getElementById without Webbrowser xD
If possible..
If possible..
THen
Then just use the Get Element by ID
Code:
Imports System.net
Dim e as String = New Webclient().Downloadstring("?")

Not that easy, You cant do e.GetElementById("BLABLA")
if (browser.Document.GetElementbyID("freedompeace") != null)
// element exists..
// element exists..

1) If this is for your IP manager, you can try downloading the webpage's source using a WebClient and then loading the HTML/XML into an XMLDocument or whatever its called.
2) mshtml.

Im just asking if is possible getElementbyId without a webbrowser.
Use the library Jason released few days ago. And learn string manipulation.
You can do it, but it means using a COM object called HTML Object Library. It renders text into a HTML document which you can then call getElementById...etc. IMO you should just create a custom function to find it, or as Hassan said, use my library.
Here's some code that I'd start with, using RegEx
[highlight=vb.net]
Imports System.Text.RegularExpressions
[/highlight]
[highlight=vb.net]
Private Function ReplaceMetachars(ByVal input As String) As String
Dim output As String = input
Dim chars As String = "[\+*?(|$^.)"
For Each s As String In chars
output = output.Replace(s, "\" & s)
Next
Return output
End Function
Private Function GetElementByID(ByVal ID As String, ByVal src As String) As String
Dim idPattern As String = "<([a-zA-Z]*)\s.*?id=""" & ReplaceMetachars(ID) & """[\s\S]*?</\1>"
Dim m As Match = Regex.Match(src, idPattern, RegexOptions.Compiled)
Return m.Value
End Function
[/highlight]
And after that I'd probably build a custom "Element" class to do various operations on the value so that it's similar to a HTMLElement in terms of functionality. Then I'd make the function return an "Element" instead of a raw string.

Jason, what if the tag contains numbers ?
Modified a bit to support numbers in tag:
[highlight=vbnet]Dim idPattern As String = "<([a-zA-Z0-9]*)\s.*?id=""" & ReplaceMetachars(ID) & """[\s\S]*?</\1>"[/highlight]
