在空白处分割字符串，但在HTML标记内排除

Question

I have this decoded html string <div style=\\"text-align:right; \\">test1 <strong>test2 </strong>test3 test4 test5</div>

I need to split them in whitespaces but should not split spaces in html tags, so I will have the following split in 5. I'm not a regex guy so I need help.

<div style=\"text-align:right;\">test1

<strong>test2

</strong>test3

test4

test5</div>

EDIT: I included </strong> and add another line to make another point.

Answer 1

You can split based on ' <' or '> ' :

string value = <div style=\"text - align:right; \">test1 <strong>test2 </strong>test3</div>;
string[] listHtml = Regex.Split(value, "( <)|(> )");

Answer 2

This turned out kinda ugly but works, probably better way than this (may just use htmlagility pack):

        List<String> finalList = new List<string>();
        bool insideHtml = false;
        StringBuilder sb = new StringBuilder();
        string[] test = "<div style=\"text - align:right; \">test1 <strong>test2 </div>".Split(' ');

        foreach (string t in test)
        {
            if (t.Contains("<"))
            {
                sb.Append(" " + t);
                insideHtml = true;
                if (t.Contains(">"))
                {
                    finalList.Add(sb.ToString());
                    sb.Clear();
                    insideHtml = false;
                }
            }
            else if (t.Contains(">"))
            {
                sb.Append(" " + t);
                finalList.Add(sb.ToString());
                sb.Clear();
                insideHtml = false;
            }
            else
            {
                if (insideHtml)
                {
                    sb.Append(" " + t);
                }
                else
                {
                    finalList.Add(t);
                }
            }
        }
