String manipulation function in C#

[LoveToCode]

Hi,

I'm building a Screen Scraper in C# using the WebResponse and WebRequest classes. I get the whole HTML page in one long big ass string.

Now, I need to find certain elements in that HTML. All the elements I need are encased in some kind of tag. For example:


<span id="username">Jenni Quick!</span>

So I think I should write a function that can find an element by the starting tag.


this is what I have so far, but I need help with searching the strings:

 private string fineElement(string findText, string origText)
    {
        int nIndexStart = 0;
        int nIndexEnd = 0;
        int nIndex = 0;

        string result = string.Empty;

        nIndexStart = origText.IndexOf(findText);
        
        result = // what do I do here?? :(

        return result;

}

The problem is how do I search from the start index to the end of the result, which is from the start index to the first instance of a "<" character directly after the start index.

THank you!!

Have a look into using the RegEx class and try creating (or having a look at some existing) regular expressions as they are much more suited to finding patterns.
