Regular expression to grab unknown value

[Eric Cathell]

I have a string of data coming from a device. I have to pull the data out of
the string that I need to put into an object.

this is an example of my return string:

each property in my object matches a return value(ie there is a property
called ecgSt1)

so I really need to know how to pull out the value between the = and the ;

ecgSt1=-65;ecgSt2=+65;e cgSt3=-45;p1=21,45,54; p2=45,55,21;t1= 99;hr=45;hrSour ce=;nibp=;nibpE lapsedTime=;res p=;respSource=; co2=;spo2=;o2=; agent=;agentTyp e=;n2o=


x.ecgst1=regex. Something(patte rn,string)etc.. . this should pull the value
between the = and the ;


I have searched pretty thouroughly on the web, but I cant seem to get the
right search terms going.

Re: Regular expression to grab unknown value

using the following regex you'd get a MatchCollection with app possible key/value
pairs which can be added to a SDictionary quite easily. You'd be on your
own from there:

(?<key>[^=]+)=(?<value>[^;]+);

regex rx = new Regex("(?<key>[^=]+)=(?<value>[^;]+);", RegexOption.Non e);

Dictionary<stri ng, stringresult = new Dictionary<stri ng, string>();

Match m = rx.Match(yourSt ring);
while (m.success)
{
result.add=(m.G roups["key"].Value, m.Groups["value"].Value);
}
//Result now has all keys and values in an easily accessible collection.

Alternatively you could use:

(?:(?<key>[^=]+)=(?<value>[^;]+);)*

regex rx = new Regex("(?:(?<ke y>[^=]+)=(?<value>[^;]+);)*", RegexOption.Non e);

Match m = rx.Match(yourSt ring);
if (m.success)
{
foreach(int i = 0; i < result.Groups["key"].Captures.Count ; i++)
{
string key = result.Groups["key"].Captures[i];
string value = result.Groups["value"].Captures[i];
}
}
