get SRC attribute from image tag that is coming from database

get SRC attribute from image tag that is coming from database

I'm getting a string back from the database that is:

var x = ImageValue; 

the ImageValue= <img alt=""  src="/newImage.gif" style="border: 1px solid;"/>  //this is what is coming from the database

how can I split [ImageValue]  to only get the src tag, so I get it as:

src="/newImage.gig"

that's the only section of this string I need
