Hi All,
I have a scenario where i need to replace

tag with
tag

Initial Code

XML

<div> some text </div>
<div style="any style"> more text</div>

-----------------Code implemented---------------------------------------------------

XML

<div> replaced with <br>
</div> replaced with String.Empty

<div style="any style"> not getting replaced :(

------------------------------------------------------------------------------------

------------------------Code--------------------------------------------------------

C#

public string ReplaceDivTagToBrakeTag(string data)
        {
    return data.Replace("<div>","<br>").Replace("</div>", String.Empty)).ToString();
        }

------------------------------------------------------------------------------------

Final Output

XML

<br> some text
<br> more text

The problem:
It's easy to replace the simple

tag but when a div tag with style came it will not replace it i.e.

not getting replaced.

Please provide a solution :)

Cannot you use just 'textContent' property of a tag?

document.getElementsByTagName('div')[0].textContent

Solution 3

C#

using System.Text.RegularExpressions;

[...]

C#

private string ReplaceDivTagToBrakeTag(string data)
{
  Regex regEx = new Regex(@"<div.*>(.*)</div>");

  Match m = regEx.Match(data);

  return "<br>" + m.Groups[1].Value.Trim();
}

Hi Michel,
Thanks for this solution i think we are bit closer to the solution but a single problem this is the implementation i used please see the normal <div> is not getting replaced

static string ReplaceDivTagToBrakeTag(string data)
{
Regex regEx = new Regex(@"<div.*>(.*)</div>");

Match m = regEx.Match(data);
return m.Groups[1].Value.Trim();
}
static void Main()
{
string text = "<div> some text </div> <div style=\"any stlye\"> more text </div>";
System.Console.WriteLine("text=[" + text + "]");

System.Console.WriteLine("result=[" + ReplaceDivTagToBrakeTag(text) + "]");
System.Console.ReadLine();
}

And i want to replave there div with BR

Solution 1

You need to handle it (style with div) separately........

data.Replace("<div>", "<br>").Replace("</div>", String.Empty).Replace("<div style=any style>", "<br>").ToString();

Hey thanks for the reply but the problem is .Replace("<div style=any style>", "<br>"))
in this We are not sure about style="any style" as it can be any style as Border:1px or Colou:red
so this will not work

Then you have to go with Regex.Match, i dont know much abt this one, but definitely will get solution with Regex.Match

n.podbielski · Answer 3 · 2012-10-15T22:51:00

So maybe you will parse this data as XML.

http://msdn.microsoft.com/en-us/library/cc189056%28v=vs.95%29.aspx

This way you will not have to change it everytime data will change.
I am not sure if xml parser will be sufficient for this. I should if your data will be simple enough and formatted correctly. For more complicated cases use one of non standard HTML parser libraries (http://htmlagilitypack.codeplex.com/[^] this looks promising).

As for parsing it with regex read:

http://www.codinghorror.com/blog/2009/11/parsing-html-the-cthulhu-way.html

I know that RegExp is simple, but you have problems already with this, and with RegExp and Html are always problems (been there, done that and it will not happen again).
