Accessing semicolon delimited items in a MSBuild Variable

I have a variable that I am working with called $(TargetConnectionString)

It is set to

SomeValue=Things;Data Source=MySQLServer;Integrated Security=True;Pooling=False

Is there a cool MSBuild way to get a reference to just the MySQLServer part of this list?

(I c开发者_如何转开发an use a batch file to parse it, but then I have to find a way to read it back in. So I am hoping there is a way to say $(TargetConnectionString."Data Source") (or something similar)

So, how can I get to get the MySQLServer text.

the following works, by calling back into the project file using an MsBuild task with the TargetConnection string as property set. Does not work with spaces though, so I removed them, hopefully that's usefull for you

<?xml version="1.0" encoding="utf-8"?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

  <PropertyGroup>
    <TargetConnectionString>DataSource=MySQLServer;IntegratedSecurity=True;Pooling=False</TargetConnectionString>
  </PropertyGroup>

  <Target Name="Main">
    <MSBuild Projects="$(MSBuildProjectFullPath)" Targets="GetDataSource" Properties="$(TargetConnectionString)"/> 
  </Target>

  <Target Name="GetDataSource">
    <Message Text="$(DataSource)"/>
    <Message Text="$(IntegratedSecurity)"/>
    <Message Text="$(Pooling)"/>
  </Target>

</Project>

output:

> msbuild test.proj /t:Main
...
