I have a Socket communication in my Windows Phone app, but when I call it I can sometimes get a result, that looks like this
\0\0\0\0<RESULT><DATA>...</DATA></RESULT>\0
I want to remove the start and the end of it so I only get the XML, but what is the best way to do it? I have thought about Regex, but I can not make it work :(
It sounds like a problem with your protocol, but to remove the \0 characters you could do a simple trimming of the string.
If your string has the actual \ and 0 characters in it then you could do the following:
var fixedData = receivedData.Trim(new[] { '\\', '0' });
And if the string starts with null characters (encoded as \0) then you could to:
var fixedData = receivedData.Trim(new[] { '\0' });
Both examples assume that the variable receviedData is a String containing your data.
I have not enough information to answer you correctly, so I will suggest the following :
You should try to map the data you are receiving from your socket to a serializable class. And then you serialize the classObject to an XML document.
public class socketDataToMap
{
public string Data {get; set;}
}
and then
var ser = new XmlSerializer(typeof(socketDataToMap));
using (var reader = XmlReader.Create(yourSocketStream))
{
var deserializedObject = ser.Deserialize(reader) as socketDataToMap;
}
and then you serialize to an XML file. I see something like this for your problem.
If your result have to be XML and more characters(else \0) can be in start or end of your string, these code can be useful:
var start = inputString.IndexOf('<');
var end = inputString.LastIndexOf('>');
var result = inputString.Substring(start, end - start);
String.IndexOf Method (Char): Reports the zero-based index of the first occurrence of the specified Unicode character in this string.String.LastIndexOf Method (Char): Reports the zero-based index position of the last occurrence of a specified Unicode character within this instance.String.Substring Method (Int32, Int32): Retrieves a substring from this instance. The substring starts at a specified character position and has a specified length.
string xml = ReturnString.Trim('\0');I guess.
