Extract SRC of IMG with specific ID in PHP

I know that this question has been posted a lot of times and I read through all the previous questions. I could not find a way to make this work.

I need to extract the src url of an img tag with a particular id. Input format is -

<img class"image" id="prdImage" width="277" height="400" alt="someimage" src="http://url/image.jpg"/>

src attribute is always the last, class is always the first. Also, this code will be in a large HTML document. I only gave the relevant part.

What I have till now-

/<img class="image" id="prdImage".+?src="(.+?)".+?\/>/i

This is working fine except that it is returning the entire img tag instead of only the src attribute;

Note: I know that I should use a DOM parser for such cases. But for this project, I can only use regular expressions.

I figured out the answer myself. Here is the expression

/<img class="image" id="prdImage"(.*?)src="(.*?)"\/>/i

This will return an array with the url in the second position.

I am accepting this answer since I figured it out myself. If anybody else has a better solution, I will accept their answer.

Try this

(?<=<img.*?src=")(.*?)(?="/>)

That regex will return 

http://url/image.jpg

from your input string

<img class"image" id="prdImage" width="277" height="400" alt="someimage" src="http://url/image.jpg"/>
