How to Get the value of an element in a web page 1

[sarcus25]

Hi I'm trying to get the value of a element nested inside an object using the webbrowser control. How would I got about doing this. Thanks in advance.

The html code I'm trying to extract the value from is as follows:

<OBJECT>

<PARAM name="SRC" VALUE="Value To be extracted">

</OBJECT>

How much do you know about the DOM (document object model)? You can access the DOM for a page in the webbrowser control using

[i]wbBrowserCtl[/i].document.body.[i]attribute[/i]

Also, check into:
getElementById("id")
And
getElementsByName("name")
And possibly:
getElementsByTagName("tag")

Note that GetElementById returns a single Element...
But, the other 2 functions return Collections (Arrays of Elements) which you will have to specify which you want to use...
Such As...

X = wb.document.body.getElementsByName("SRC")[b](0)[/b].value

However, if the element is not found, the .value will result in an "Object Not Set" error, so it is better to use:

[b]Dim E as object
Set E =[/b] wb.document.body.getElementsByName("SRC")[b](0)[/b]
[b]If Not E Is Nothing Then[/b] X = [b]E.[/b]value

Or you could be lazy (like me most of the time )

[b]On Error Resume Next[/b]
  X = wb.document.body.getElementsByName("SRC")[b](0)[/b].value
[b]On Error Goto 0[/b]
