How to split text with HTML tags to array

Question

I have very simple text with HTML (only  tag) e.g.

Lorem Ipsum is simply dummy text of the printing and typesetting industry

I would like to split the text to array like this:

[0] - Lorem Ipsum is 
[1] - <b>simply dummy</b>
[2] - text of the printing and
[3] - <b>typesetting industry</b>

The text inside HTML tag must be separated from another text. Is there any simple solution for it?

Thank you

have you tried something using Split() function or using regular expressions? — Mivaweb

^ for your knowledge. Html cannot be parsed correctly with regex stackoverflow.com/questions/1732348/… — Razvan Dumitru

But in this case you can instantiate an array and add [0] - Lorem Ipsum is till you find . When you find , you search for the next and you place the between text in the array [1] - simply dummy and so on. Like a minimal parsing algorithm. This will work if you don't have nested 's. — Razvan Dumitru

there's a lib called htmlagility pack that does this for you if you're allowed to use 3rd party libs. — Thomas Lindvall

You may achieve this using following code

string value = @"Lorem Ipsum is <b>simply dummy</b> text of the printing and <b>typesetting industry</b>";
var parts = Regex.Split(value, @"(<b>[\s\S]+?<\/b>)").Where(l => l != string.Empty).ToArray();

I just wrote this, tested it and it works. It's a bit ugly but it works hahah

    public string[] getHtmlSplitted(String text)
    {
        var list = new List<string>();
        var pattern = "(<b>|</b>)";
        var isInTag = false;            
        var inTagValue = String.Empty;

        foreach (var subStr in Regex.Split(text, pattern))
        {
            if (subStr.Equals("<b>"))
            {
                isInTag = true;
                continue;
            }
            else if (subStr.Equals("</b>"))
            {
                isInTag = false;
                list.Add(String.Format("<b>{0}</b>", inTagValue));
                continue;
            }

            if (isInTag)
            {
                inTagValue = subStr;
                continue;
            }

            list.Add(subStr);

        }
        return list.ToArray();
    }
