[VBuild_Rookie]

I'm trying to use the Replace In file step for replacing values in an xml file...I have these tags
<BuildNumber version = x.x.x.x/>
<DataCenter name = "blah"/>
<Environment name = "blah"/>

I have this is the step
<BuildNumber version = [[^<]]/>
<DataCenter name = [[^<]]/>
<Environment name = [[^<]]/>

doesn't work but if I have just one set like
<BuildNumber version = x.x.x.x/>
and
<BuildNumber version = [[^<]]/>

works fine....I need to replace all 3 in one step....is there a way??
