i have full academic copy of VS 2005 isos that i could put somewhere.

also if you are wanting to parse html files i suggest using some sort of XML parser. the only problem is i highly doubt many pages of the internet are valid xml documents.

sry for dbl post.

tokenize a string.

<img src="...." height="" width="" alt="">
if you tokenize by just the " " standard space, you would get
array[] = "<img", "src="...."", ..etc;

ofc you could then tokenize those items more if you wanted the data in the src tag for instance. you would loop over all tokens and find the one that has a sub string of src.
then take that token and tokenize it against "=". the 2nd token would have the src data,

Maybe thats what your looking for?

Definitely use regex for this.

Definitely use regex for this.

using System.Text.RegularExpressions;Sample code
//Check for correct format of txtFname

Dim myMatch As Match = System.Text.RegularExpressions.Regex.Match(WEB PAGE OR SOMETHING, "^[A-Z][a-zA-Z]*$")

[Mysterio]

Dim someshit As Match = Regex.Match(htmlCode, "<img src=""(.*?)"">", RegexOptions.IgnoreCase)

someshit.groups(1).tostring() will be the url of the image.

Ok, I will look into regex.

Thanks to Zain and Audio for the help!

Here is the parse code in VBNet to get between two pieces of text..

Public Function Parses(ByVal sdata As String, ByVal delim1 As String, ByVal delim2 As String) As String
Return sdata.Substring(sdata.IndexOf(delim1) + delim1.Length, sdata.IndexOf(delim2) - (sdata.IndexOf(delim1) + delim1.Length))
sdata.Substring(sdata.IndexOf(delim1) + delim1.Length, (sdata.Length - sdata.IndexOf(delim2)))
End Function

Example

Dim TitlePage As String

TitlePage = Parses(htmlData, "<title>", "</title>")

would grab between <title> and </title>

Thanks again guys.
