[VB.NET]Parsing text between HTML tags

try this

Code:

 Dim str As String
    Dim strArr() As String
    Dim box3 As String

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        str = <li class="ReleaseDate"><label>Release date:</label> 12/16/2010</li>
        strArr = str.Split(" ")
        box3 = strArr(2)
       TextBox3.Text = box3

the reason this works is the the variable str is actually equal to "Release Date: 12/16/2010" because it reads the html so when i split with the .split method 3 things are put into the string array (strArr) Release, Date, and then the number series since arrays start at 0 the third is actually strArr(2)
if you put

Code:

 messagebox.show(str)

you can see what str is actually equal to

 

here ya go i tested it

Code:

 Dim loc As Integer
    Dim str As String

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        Dim srchString As String = "<label>Release date:</label>" 'Storing the string I'm looking for

        Dim net As New Net.WebClient() 'Add webclient

        Dim src As String = net.DownloadString("http://marketplace.xbox.com/en-US/Product/Fable-III/66acd000-77fe-1000-9115-d8024d5308d6") 'Downloading the HTML

        Dim rd As String

        rd = src.Substring(src.IndexOf(srchString) + srchString.Length, 50) 'Grabbing the data I want

        'This above code returns > "6/8/2011</li> <li class="FileSize"><labe" - Now, how can I trim EVERYTHING past </li>????
        'finds the start of </li>
        loc = rd.IndexOf("</li>")
        'removes everything past li with +5 to include the li because indexof returns the first character then puts 
        'the trimmed string into str
        str = rd.Remove((loc + 5))
        TextBox2.Text = str
    End Sub

btw how do you keep the color in the code tags when u paste on here

 

Have you considered using regular expressions?

The following expression matches all the dates in the HTML source:

Code:

\d{2}/\d{2}/\d{4}

Test it with [C#]:

Code:

StringCollection resultList = new StringCollection();

try
{
Regex regexObj = new Regex(@"\d{2}/\d{2}/\d{4}", RegexOptions.Multiline);
Match matchResult = regexObj.Match(subjectString);

while (matchResult.Success)
{
resultList.Add(matchResult.Value);
matchResult = matchResult.NextMatch();
} 
}
catch (ArgumentException ex)
{
// Syntax error in the regular expression
}

[VB.NET]:

Code:

Dim ResultList As StringCollection = New StringCollection()

Try
Dim RegexObj As New Regex("\d{2}/\d{2}/\d{4}", RegexOptions.Multiline)
Dim MatchResult As Match = RegexObj.Match(SubjectString)

While MatchResult.Success
ResultList.Add(MatchResult.Value)
MatchResult = MatchResult.NextMatch()
End While
Catch ex As ArgumentException
'Syntax error in the regular expression
End Try

You can create more complex expressions depending on how you want to solve the problem. If you know that the string you're checking contains one, and only one date, then the following will work fine to retrieve it [C#]:

Code:

string resultString = null;

try
{
resultString = Regex.Match(subjectString, @"\d{2}/\d{2}/\d{4}", RegexOptions.Multiline).Value;
}
catch (ArgumentException ex)
{
// Syntax error in the regular expression
}

[VB.NET]:

Code:

Dim ResultString As String

Try
ResultString = Regex.Match(SubjectString, "\d{2}/\d{2}/\d{4}", RegexOptions.Multiline).Value
Catch ex As ArgumentException
'Syntax error in the regular expression
End Try

And don't forget [C#]:

Code:

using System.Text.RegularExpressions;

[VB.NET]:

Code:

Imports System.Text.RegularExpressions

You can skip the try/catch-blocks if you want, but they might be useful if you change the expressions often.

 

I hear ya. However, as long as the data is equally formatted everywhere, a regular expression will always work.

Eventually, you could try the HtmlAgilityPack.
