Question

I have a string:

<div class="className1234"><p>Some html</p></div>

From this string, I would like to get <p>Some html</p> i.e. I would like to remove the surrounding div tags based on the fact that it’s class contains ‘className’.

What I’ve Tried

What I’ve tried works, but it’s cludgey – and I know there’ll be a better alternative like regex or something. What I currently do is chain a series of substring(), indexof() and replace() calls to strip out the divs.

EDIT: I’ve used the phrase ‘innerhtml’ because I’d like to think there’s a library out there somewhere that would allow me to manipulate a string with regard to the tags within it.

PLEASE NOTE: There’s no JQuery involved in this. It’s all server-side C#.

How about:

XmlDocument doc = new XmlDocument();
doc.LoadXml(divStr);
// classAtr will be null if the root is not a div with a class with the value className1234
XmlNode classAtr = doc.SelectSingleNode("/div/@class[contains(., 'className1234')]");
string result = classAtr != null ? doc.DocumentElement.InnerXml : divStr;
