I have code that gets the first h1 tag from a webpage. Now I want to get the first img tag that appears either before or after this h1 tag. How can I do this using PHP Simple HTML DOM?

you could use preg_match and get the first in the array. – Elliott Aug 03 '12 at 19:54

Not easily. However, this should probably work:
- Get the
<h1>as you have already - Get the next sibling. Check if is an image, or if not check if it has an image as a child/descendant
- Get the previous sibling. Same checks as above.
- If you haven't found an image yet, get the next sibling ahead, and the previous behind, and repeat until you do or you run out of nodes.
- If you still have no image, take the parent node of the
<h1>and repeat the entire process from Step 2. - You should now have traversed the entire document, so if you have no result now then there's just no images anywhere.
Trim steps as needed.
