Replace image url's in WordPress export file

Question

Is there an easy way I can replace all the image urls in a WordPress export file with a different url which I can use to replace all the images with a placeholder image.

Currently in the xml file the paths to the images are as follows :

<guid isPermaLink="false">http://demo.mydomain.com/theme/wp-content/uploads/2016/10/IMAGE_161008_159-1500x1200.jpg</guid>

I need to change all the urls to something like this instead :

http://mytheme.com/placeholder-image.jpg

Any ideas how ?

ideally id like to do it using regex search replace in Atom

Thanks.

Replace:

http://mytheme.com/placeholder-image.jpg
