Hi All,

I just want to remove the before and after spaces from html string through regular expression.
My html string is just like

HTML

<div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div><div>Hi This is lalit singh rathour</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div>

and 

<div><span><br></span></div><span><div><span><br></span></div>A&nbsp;</span>tightly coupling<span>, means where the one object/entity needs to have knowledge of other objects or we can say they depend largely on the interfaces where the service methods are declared. This can be avoided in small applications, but in large applications, these terms are required to be kept in mind else, it may lead to chaos.</span><div></div><div><span><br></span></div><div><span><br></span></div><div><span><br></span></div><div><span><br></span></div><div><span><br></span></div>

will you help how can i extract the html string without before and after spaces.

If you mean spaces as in <br> tags always surrounded by <div> tags, you can simply try String's Replace method:

C#

String cleanedText = originalText.Replace("<div><br></br></div>","");

For more advanced matching you can turn to Regex.Replace, e.g:

C#

String cleanedTerxt = Regex.Replace(originalText, "<div>\s*<br>\s*</br></div>", "");

to also remove occurances where there is whitespace between the tags. Regex is a bit tricky to get right but you can for instance use https://msdn.microsoft.com/en-us/library/az24scfc(v=vs.110).aspx[^] as a reference.

Good luck.
