Hi Friends

I need to find a value from an XML string. since my Xml string is messed up i am not able to parse. so my question is, whether with help of some regex expression or using any other way can i pick up the value
For example this is my

<NUM_AE>147</NUM_AE>

string
i need to get the value 147
How its possible?
thanks in advance

string inputString ="asjkdfkas djasdasdjasjd<>sfkasdfkaslkfa<NUM_AE>147</NUM_AE><b>sdfsdfsdf</b>sdfsdfsdfsdf";
Regex regex = new Regex("<NUM_AE>(.*?)</NUM_AE>");
var regMatch = regex.Match(inputString);
string value = regMatch.Groups[1].ToString();

check RegEx C# : Find a string between 2 known values[^]
