Find text in file, read to specific character is found

[R4PM0NK3Y]

Hi, I need to do this:

 

First, open a text file. Read the file until it finds the phrase "test". Once found, it needs to read the text to the right of it into a string variable, until the character "<" is reached. How could I do this? Any help is greatly appreciated!

'declare a stream reader giving it the file name
       Dim FileReader As New StreamReader("PathOfTheFile")
       Dim FileContent As String = FileReader.ReadToEnd() 'reads the whole file into a string
       Dim i As Integer = FileContent.IndexOf("test")
       If i <> -1 Then
           'the file contains the word test
           'declare a string to hold the text from test to <
           'take a part of the string from where test is found + 4 (length of test)
           Dim Result As String = FileContent.Substring(i + 4)
           'now find where < is found in this string
           i = Result.IndexOf("<"c)
           If i <> -1 Then
               'the result string contains <
               'take the string from the beginning till the last character (just before the <)
               Result = Result.Substring(0, i - 1)
               'now result contains the string you want
           End If
       End If

 

Hope this helps,

Thanks a ton, this should work! :D

That DID work (thanks a ton), but I made some modifications and have one more question.

 

In this line:

 

i = result.IndexOf("<"c)

 

What does the "c" after "<" do? I need to change "<" to a variable name, and it seems the c is of importance, and I cannot have a variable name and the c in there. Example:

 

i = result.IndexOf(varc)

 

Assume the variable used is "var".

What needs to be done? Thanks again.

In "<"c , the c simple tells the compiler to treat "<" as a character rather than a string. If you are using a variable then it isn't needed.
