Rich Text Length

Unity Engine

I need length of a rich text string in terms of characters. How can I do it without manually stripping it of all tags?

You can create a simple helper method like this:

public int TextLength(string richText)
{
    int len = 0;

    foreach (var ch in richText)
    {
        bool inTag = false;

        if (ch == '<'')
        {
            inTag = true;
        }
        else if (ch == '>')
        {
            inTag = false;
        }

        if (inTag)
        {
            continue;
        }

        len++;
    }

    return len;
}

DISCLAIMER : i never tested this, but you can get the rough idea.

…and before anyone else just grabs the above optimistically, here’s it working:

    public int TextLength(string richText)
    {
        int len = 0;
        bool inTag = false;

        foreach (var ch in richText)
        {
            if (ch == '<')
            {
                inTag = true;
                continue;
            }
            else if (ch == '>')
            {
                inTag = false;
            }
            else if (!inTag)
            {
                len++;
            }
        }

        return len;
    }
