Hello,
I have a string:
Here is <input style="width: 100px; height: 22px;" type="text" /> and <input style="width: 100px; height: 22px;" type="text" /> and <input style="width: 100px; height: 22px;" type="text" />.

I would like to replace <input /> with following items: "house; car; ship"
The result should be:
Here is house and car and ship.

How is best to do this?

You could do:

string template = "Here is <input style=\"width: 100px; height: 22px;\" type=\"text\" /> and <input style=\"width: 100px; height: 22px;\" type=\"text\" /> and <input style=\"width: 100px; height: 22px;\" type=\"text\" />.";
string placeholder = "<input style=\"width: 100px; height: 22px;\" type=\"text\" />";
string items = "house; car; ship";
string[] replacements = items.Split(';');
string result = template;
int index = result.IndexOf(placeholder);
int currentReplace = 0;
            
while (index >= 0)
{
    result = result.Substring(0, index) + replacements[currentReplace].Trim() + result.Substring(index + placeholder.Length);

    index = result.IndexOf(placeholder);
    currentReplace++;
}

Or slightly more elaborate:

using System.Text.RegularExpressions;

...

string template = "Here is <input style=\"width: 100px; height: 22px;\" type=\"text\" /> and <input style=\"width: 100px; height: 22px;\" type=\"text\" /> and <input style=\"width: 100px; height: 22px;\" type=\"text\" />.";
string placeholder = "<input style=\"width: 100px; height: 22px;\" type=\"text\" />";
string items = "house; car; ship";
string[] replacements = items.Split(';');
int index = 0;

string result = Regex.Replace(template, Regex.Escape(placeholder), delegate(Match m) { return replacements[index++].Trim(); });

Do note that in either of the above, it is assumed that the template has the same number of placeholders as the replacement string has values to replace. If these don't match, then you will get an exception.

The problem is that the width and height may differ.
Is it not possible to replace all items that start with <input and end with  /> ?

In the 2nd snippet I provided, change line 6 to:

string placeholder = "<input [^>]+/>";

Open in new window


...and change line 11 to:

string result = Regex.Replace(template, placeholder, delegate(Match m) { return replacements[index++].Trim(); });
