matching multiple values using one regex?

i am having this regex to match on this given data. it must match every reference name(include) and also it should match other values if its given there. source data ..

<Reference Include="Interop.ERMSPlugin, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b5fdd3f42e76a9c0, processorArchitecture=MSIL">        <HintPath>C:\Program Files (x86)\Epiplex500\epiplex\Bin\SharedInterop.ERMSPlugin.dll</HintPath>
      <Private>False</Private>
</Reference>
<Reference Include="LicenseProcessing">
 <HintPath>C:\Program Files (x86)\Epiplex500\epiplex\Bin\Shared\LicenseProcessing.dll</HintPath>
</Reference>
<Reference Include="Snapshot">
      <HintPath>C:\Program Files (x86)\Epiplex500\epiplex\Bin\Shared\Snapshot.dll</HintPath>
</Reference>
    <Reference Include="System" />
    <Reference Include="System.Data" />

i am using this regex.

<Reference Include="(?:([^,|"]+?)[,|"]|[\s\S]*?Version=([^,]+?),[\s\S]*?PublicKeyToken=([^,|"]+)\S([^">]+?)[\s\S]*?<HintPath>([\s\S]*?)<\/HintPath>[\s\S]*?)

Here is a solution based on the Microsoft.Build and still using regular expressions:

Add the reference by right-clicking the [Solution] > Add References..., selecting Assemblies > Framework > Microsoft.Build and then hitting OK.

And here is the code itself (EDIT: now, it should process all Reference nodes):

var project = new Microsoft.Build.Evaluation.Project(@"FILE_PATH.csproj");
var references = project.Items.Where(p => p.ItemType == "Reference").Select(p => p);
foreach (var reference in references)
{
      var ReferenceName = Regex.Match(reference.EvaluatedInclude, @"^[\w\.]+(?=,\p{Zs}|$)", RegexOptions.CultureInvariant).Value;
      var version = Regex.Match(reference.EvaluatedInclude, @"(?s:(?<=Version=)([\d\.]+))", RegexOptions.CultureInvariant).Value;
      var keyToken = Regex.Match(reference.EvaluatedInclude, @"(?s:(?<=PublicKeyToken=)([\w\-]+))", RegexOptions.CultureInvariant).Value;
      var hintpath = reference.GetMetadata("HintPath") != null ? reference.GetMetadata("HintPath").EvaluatedValue : string.Empty;
}

EDIT2: In case there are problems with matching the values in the Inlcude attribute, you can also use these regexes that are just matching all non-space characters before a "comma+space" or a line end:

var ReferenceName = Regex.Match(reference.EvaluatedInclude, @"^[^\p{Zs}]+(?=,\p{Zs}|$)", RegexOptions.CultureInvariant).Value;
var version = Regex.Match(reference.EvaluatedInclude, @"(?s:(?<=Version=)([^\p{Zs}]+(?=,\p{Zs}|$)))", RegexOptions.CultureInvariant).Value;
var keyToken = Regex.Match(reference.EvaluatedInclude, @"(?s:(?<=PublicKeyToken=)([^\p{Zs}]+(?=,\p{Zs}|$)))", RegexOptions.CultureInvariant).Value;
