| Expression |
src[^>]*[^/].(?:jpg|bmp|gif)(?:\"|\') |
| Description |
This expression will return the src (source) property of an image tag <IMG>. The source returned is limited to the file extensions supplied. It doesn't matter if the image is prefixed with '../' or 'http://..blah' or 'drive\path' or nothing. This expression could be modifed to return other sources or for the tags (ie <BGSOUND>, <SCRIPT>, etc.) depending on the file extensions given.
I needed this to replace the source of images in a HTML page when I wanted to save the page to a local drive and keep the images intact.
If anybody could modify this further to include only the <IMG> tag, I would appreciate the effort. |
| Matches |
src="../images/image.jpg" | src="http://domain.com/images/image.jpg" | src='d:\w |
| Non-Matches |
src="../images/image.tif" | src="cid:value" |

slight modification to allow spaces between the attribute name (src) and the equal sign (=) and value (("|')...("|')), and also betwen the '/' (if present) and '>':
\<\s*img\s+[^>]*?src\s*=\s*('|")(.*?)\1[^>]*?\/?\s*\>

matching <img> tags only:
\<\s*img\s+[^>]*?src=('|")(.*?)\1[^>]*?\/?\>
You'll need param 2 (\2); param 1 is for consitent quoting (ending quote is same as beginning).
Don't forget to use single quotes ('; need to escape these then) or escape backslashes (\) when using PHP!

You have an error in your expression:
the dot '.' needs to be escaped otherwise it matches any character (ie src="blahblahblahjpg" works, the dot '.' matchs the 'h' from the last blah).

If the expression is used in php, you have to add a backslash in front of the slash in the statement.
Title: Match IMG tag but return SRC property

Thanks David Rolston for your modifications!
I would like to know if there is a way to match the IMG tag but just return the SRC property value. This would eliminate matching other potential tags that also have the SRC property. If this can be done, what changes would be needed for the above regular expression to match any file extension?

I think this adds the <img requirement you're looking for. This does suppose that a case insensitive modifier would be applied.
<img[ ]+[^>]*src[^>]*[^/].(?:jpg|bmp|gif)(?:\"|\')
